How to Store Butternut Squash [to Save Harvest]

By Sarwat Rehman

Butternut squash is a versatile and nutritious vegetable that can be used in a variety of dishes, from soups and stews to salads and roasted vegetables. However, to get the most out of your butternut squash, it’s important to know how to store it properly.

In this article, we’ll share essential technique for storing harvested butternut squash to prolong its shelf life, preserve its nutritional value, and ensure that it stays fresh and flavorful for as long as possible. Before that, you will get to know about ideal storage conditions and location for butternut squash.

Let’s explore everything about how to store butternut squash.

Ideal storage conditions for butternut squash

The ideal storage conditions for butternut squash are cool, dry, and dark. Here are some specific recommendations for storing butternut squash:

  1. Temperature

The temperature for storing butternut squash should be between 50 to 55 degrees Fahrenheit (10 to 13 degrees Celsius). Temperatures that are too cold or too warm can cause the squash to spoil or deteriorate more quickly.

  1. Humidity

The ideal humidity level for storing butternut squash is around 50-70%. High humidity can cause the squash to rot or mold, while low humidity can cause it to dry out and lose flavor. Therefore, it is important to store butternut squash in a location that has moderate humidity levels. If you are storing the squash in a dry environment, you can place a damp cloth or paper towel nearby to help maintain the humidity level. Conversely, if the environment is too humid, you can use a dehumidifier to reduce the moisture in the air. By maintaining the right humidity level, you can help to extend the shelf life of butternut squash and preserve its quality and flavor.

  1. Ventilation

Ventilation plays an important role in storing butternut squash as it helps to prevent the build-up of moisture and mold. Good air circulation allows any excess moisture to evaporate and helps to maintain a moderate humidity level. Without proper ventilation, the environment can become too humid, which can cause the squash to rot or mold.

  1. Darkness

Butternut squash should be stored in a dark place to prevent it from being exposed to light. It is important to note that even a small amount of light exposure can cause damage to butternut squash over time. Exposure to light can cause butternut squash to break down and lose its nutritional value, as well as cause the skin to harden or become discolored.

  1. Separation

Store butternut squash separately from other fruits and vegetables. Fruits such as apples, bananas, and pears produce ethylene gas, which can cause the squash to ripen and spoil more quickly.

By following these ideal storage conditions, you can extend the shelf life of butternut squash and ensure that it stays fresh and flavorful for several months.

Finding ideal storage location for butternut squash

Butternut squash can be stored in several different places, as long as the conditions are cool, dry, and dark. Here are some examples of suitable storage locations for butternut squash:

  • If your pantry is cool and dry, it can be an excellent place to store butternut squash. However, make sure that it’s not too close to any sources of heat or moisture.
  • A root cellar is a traditional storage area that is perfect for storing root vegetables like butternut squash. It’s a cool, dark, and humid environment that can help keep your squash fresh for several months.
  • If you have a basement that is cool and dry, it can be a good place to store butternut squash. However, make sure that it’s not too damp, as excess moisture can cause the squash to rot.
  • If you have a garage that is insulated and stays cool, it can be an ideal place to store butternut squash. However, make sure that it’s not too humid or subject to extreme temperature fluctuations.

Remember to store your butternut squash in a single layer and avoid stacking them to prevent bruising and rot. Also, avoid storing them near fruits that release ethylene gas, such as apples or bananas, as this can cause the squash to ripen and spoil more quickly.

How to store butternut squash?

After getting storage conditions and perfect location, you are at the final step of how to store butternut squash. Here is step by step procedure:

How to store butternut squash
Storing butternut squash

Step 1 – Clean the squash

To clean butternut squash for storage, follow these steps:

  1. Rinse the squash under cool, running water to remove any dirt or debris from the surface.
  2. Use a clean vegetable brush to scrub the surface of the squash gently to remove any remaining dirt or debris.
  3. Dry the squash with a clean towel or allow it to air dry completely before storing.

It’s important to ensure that the squash is completely dry before storing, as any moisture can promote the growth of mold and cause the squash to spoil more quickly. Once the squash is clean and dry, you can proceed with the curing and storage process as described earlier.

Step 2 – Cure the squash

Curing is the process of allowing the butternut squash to dry and harden before storing it. It develops a tough outer layer that protects squashes from moisture and bacteria, preventing it from spoiling quickly and prolongs shelf life.

Here are some benefits of curing butternut squash before directly storing:

  1. Curing helps to dry out the outer layer of the squash, creating a protective barrier that prevents moisture from entering and bacteria from growing. As a result, cured butternut squash can last for several months in storage.
  2. Curing can enhance the natural sweetness of butternut squash and produce a nuttier flavor. It also helps to firm up the flesh, making it easier to cut and cook.
  3. Curing can help to preserve the nutritional content of butternut squash by slowing down the degradation of its vitamins and minerals.
  4. Cured butternut squash can be used in a wide range of recipes, from soups and stews to roasted vegetables and side dishes.

To cure butternut squash, it should be left in a warm, dry place with good ventilation for about 7-14 days, depending on the size and thickness of the squash. After curing, the squash can be stored in a cool, dry, and dark place for several months.

 

Step 3 – Storing at the right place

Choose a cool, dry, and dark location to store butternut squash as directed in the first section.

Do not stack the squash on top of each other, as this can lead to bruising and spoilage. Instead, place the squash in a single layer on a shelf or in a basket, with space between each squash to allow for air circulation.

Another option is to wrap squashes for storing. It’s not necessary, but doing so can provide an extra layer of protection against moisture and pests. If you choose to wrap the squash, use a breathable material such as paper or a loosely woven cloth. This allows for air circulation and prevents the squash from sweating and developing moisture, which can lead to mold growth and spoilage.

Perforated plastic bags also work fine. This allows for air circulation while also providing a barrier against moisture and pests.

Whether you choose to wrap the squash or not, make sure to store it in a cool, dry, and well-ventilated location with a temperature between 50-55°F and a humidity level between 50-70%.

How to Grow Butternut Squash in Small Space [3 Methods]

By Sarwat Rehman

Butternut squash is normally grown on spacious ground for its bulky size and shape but growing it in small space is also possible. You can have it in the containers, pots, raised beds or grow vertically on trellis .

Typically, butternut squash grows as long as 12 inches (30 cm) with a 3 to 6 inches (7 to 13 cm)diameter and every gardener does not have enough growing space. In such a case, finding space saving methods to grow butternut squash is the only option left.

Luckily, we have 3 easiest and practical ways of growing butternut squash in small spaces (balcony or small kitchen garden)keeping cultivation area clean.

So, let’s directly come to “How to grow butternut squash in small space” with mentioned methods.

  1. Use containers or pots
  2. Get benefit of raised garden beds
  3. Grow squashes vertically on trellis

 Method 1 – Growing Butternut Squash in Containers

How to Grow Butternut Squash in Small Space
How to Grow Butternut Squash in Small Space

Butternut squash grow well in containers depending on the butternut squash variety you have chosen and the right container size.

Here is step-by-step method for you:

1.      Decide on butternut squash variety

Butternut squash is a common winter squash and you can find its multiple hybrids with varying traits. All are not equally suitable to grow in containers for their size and weight. Normally, you will find butternut squash in two varieties – bush and vining. Bush varieties are compact and grow more fruit in small space than vining varieties that require more space. Thus, bush cultivars are best for squash container gardening in a small apartment or limited balcony space.

Here is a glimpse of different butternut squash varieties with their sizes.

After carefully selecting your favorite type of butternut squash, get into the details of how you can grow butternut squash in container or pot.

2.      Pot selection

Selecting a pot to grow butternut squash is crucial and needs considerations for pot size, material and drainage as:

Size – Butternut squash have a large root system that needs ample room to grow thus select a deep and wide container. A 5-gallon bucket that is24 inches wide and 12 inches deep proves best for growing butternut squash. It will encourage production of large sized fruits with no problems at all. You can also get benefit of empty buckets for DIY project.

Pot material and drainage – Plastic and terra cotta pots go really well for cultivating butternut squash for their porous nature. Natural grow bags also prove fine containers for this winter squash.

Remember, considering pot drainage is more important than material as poorly draining pot will kill the roots. So, make sure your selected container has 2 to 4 drainage holes at the bottom. Drill yourself if there is not any to release excess water.

Don’t forget to test grow bags before massive plantation and check how well they drain. You can also add holes at the bottom if water doesn’t leak through the bag quickly.

3.      Potting mix preparation

Butternut squash is a heavy feeder and grows well in well-draining soil. Traditional garden soil is too dense to suffocate plant roots and trap moisture in the container leading to fungal issues.

Similarly, it is normal for the garden soil to have insects and pests. Thus best approach is to start with potting mix then add equal parts compost, peat moss, perlite and sphagnum for a well-draining and nutritionally packed base.

4.      Grow squash –Seeds vs transplant

After preparing pot with the potting mix, next is the growing step. Sowing seeds and transplanting seedlings are the two options available.

Typically, squashes do not prefer to be transplanted and grow well in containers with the seeds. You can start seeds in mid spring after the soil warms up (two weeks after the threat of last frost) or start indoors 3 to 4 weeks before last frost.

Sow the seeds (2 to 3 seeds) about 1 inch deep in the slightly damp soil and be sure to follow package directions for more specific guidelines. Aim for one plant per five-gallon container so you may need to thin seedling later.

Soaking seeds in water (for 2 to 3 hours) prior to sowing helps in water absorbance and accelerates germination that is a plus point for faster growth.

If you have opted for transplanting, always use a healthy plant from nursery or garden center.

5.      Locate the container at right place

Finding the right place for butternut squash container is a task for gardeners with small space as they are already loaded with the plants. But fortunately, container gardening of this squash variety does not require you isolated space.

You can place in shade and sunny site at different times as too much exposure to direct sunlight can harm growth. Do not place newly gown plant to sunlight for more than a few hours per day. Relocate the plant to a sunny site once it has become established.

At the same time, maintain the soil temperature to 65 to 70oF for optimum growth.

Water reasonably after plantation (1 to 2 times a day) and manage it depending on the weather conditions. The last step in growing butternut squash in containers is fertilization and you can use liquid or granular NPK (nitrogen, phosphorus, potassium) fertilizer in the growing season.

Method 2 – Growing Butternut Squash in Raised Garden Beds

How to Grow Butternut Squash in Small Space

Butternut squash (Cucurbita moschata)grows exceptionally well in raised beds where space is a problem.

Raised beds are accessible and elevated planters giving more control over the soil making squash plantation easy for gardeners of all age groups. They are square boxes with or without stand for increased accessibility. You can start growing butternut squash in a square garden bed if there is no plantation space at your place.

Before directly diving in to the plantation, make sure to learn suitable garden bed for butternut squash and its right cultivar.

Step 1 – Choosing raised garden bed

Select raised garden beds based on the material and size. Here is how you can do it:

Material – Finding ready to use raised garden bed for squash plantation is not an issue but it may cost you a bit higher. On the contrary, making DIY garden bed is the cost effective approach and you can make one in less than a few hours.

Commonly used materials to build a garden bed include:

  • Lumber
  • Recycled wood
  • Rocks
  • Cinder or concrete blocks
  • Old logs
  • Boards

Size – Using an oversized raised garden bed is not a wise solution to grow butternut squashes in limited space. You must focus on the width and length to choose one that makes plantation hassle-free task.

Typically, 4 feet wide and 4 feet long (square raised garden bed) works well for squash plantation at beginner’s level in a limited space.

You can also make it longer depending on the space available.

Lastly, make raised beds deep enough to support growing root system of the winter squash. 10 to 12 inches high raised beds are ideally used to grow butternut squash.

Step 2 – Setting up raised garden bed

After carefully preparing (or installing) raised bed, next is its set up. You need to fill the soil but be sure to use organically rich acidic soil. Avoid ordinary garden soil as it is quite heavy and suffocates roots by retaining a lot of water.

The best bet is to fill the bed with loose potting mix or a combination of equal parts compost, peat moss, or coconut coir. This prepared soil will be well draining and nutrient rich for your butternut squash to thrive in limited space.

Adding a layer of hardware cloth over the ground before placing raised bed keeps insects and moles out of the box.

Step 3 – Growing butternut squash in a raised bed

  1. Choose high-quality seeds: Select seeds from a reputable source, ideally those that are certified organic. Look for seeds that are fresh and have not been treated with any chemicals.
  2. Start the seeds indoors: Butternut squash seeds can be started indoors 3 to 4 weeks before the last expected frost date in your area. Fill seed-starting trays or containers with a good quality seed-starting mix, and sow the seeds about 1 inch deep. Keep the soil moist but not waterlogged, and place the trays in a warm, bright location.
  3. Harden off the seedlings: About a week before transplanting the seedlings into the raised bed, begin to harden them off by gradually exposing them to outdoor conditions. Start by placing them outside for a few hours each day in a sheltered location, gradually increasing the amount of time they spend outside over the course of a week.
  4. Transplant the seedlings: When the seedlings have developed 2 or 3 sets of true leaves and the soil in the raised bed has warmed up to at least 60°F, it’s time to transplant them. Dig a hole that’s slightly larger than the root ball of the seedling, and carefully place the seedling in the hole. Fill in the soil around the plant, and firm it gently.
  5. Provide adequate water and fertilizer: Water the seedlings deeply and regularly, but avoid getting water on the leaves. Apply a balanced fertilizer (such as 10-10-10) every 4 to 6 weeks throughout the growing season.
  6. Monitor for pests and diseases: Keep an eye out for common pests and diseases that can affect butternut squash, such as squash bugs, squash vine borers, and powdery mildew. If you notice any signs of infestation or disease, take action promptly to prevent the problem from spreading.

Method 3 – Growing Butternut Squash Vertically

How to Grow Butternut Squash in Small Space
How to Grow Butternut Squash in Small Space

Growing butternut squash vertically offers several advantages over traditional methods of growing them horizontally. You can save valuable space in your garden. This is especially useful if you have a small garden or limited growing space.

Additionally, you get multiple benefits of growing butternut squash vertically. These include:

  • Reduces disease: Growing butternut squash vertically can help reduce the risk of diseases that often affect squash plants, such as powdery mildew and downy mildew. When grown horizontally, the leaves of the plant can trap moisture, which can encourage the growth of these diseases. Vertical growing allows for better air circulation and can help keep the leaves dry.
  • Easier harvest: When you grow butternut squash vertically, the fruit is easier to see and access, making it easier to harvest. This is especially useful if you have mobility issues or find it difficult to bend down to harvest squash that is growing on the ground.

Step 1 – Choosing right butternut variety

When it comes to vertical growing, not all varieties of butternut squash are created equal. Look for compact or dwarf varieties that won’t take up too much space.

Some good options include “Honeynut,” “Butterscotch,” and “Early Butternut.” Be sure to read the seed packet or plant label carefully to make sure you choose a variety that is suitable for vertical growing.

Step 2 – Choosing a Location for Vertical Growing

Next, you’ll need to choose the right location for your plants. Here are a few things to consider:

  • Sun: Butternut squash plants need at least 6-8 hours of direct sunlight per day, so choose a spot that gets plenty of sun.
  • Soil: The soil should be well-draining and rich in organic matter. If your soil is poor, consider adding compost or other organic matter to improve it.
  • Support: Your support structure should be sturdy and able to withstand the weight of the squash plants and fruit. It should also be located in an area that is protected from strong winds.

Step 3 – Choosing a trellis for butternut squash

When growing squash on a trellis, it is important to choose the right type of trellis to provide adequate support for the heavy vines and fruit.

Additionally, make sure the trellis has enough space for the vines to grow and be trained vertically, and that it is positioned in a spot that receives adequate sunlight and air circulation.

Here are some options for trellises that work well for squash:

  1. A-Frame Trellis: An A-frame trellis is a simple and sturdy option for growing squash vertically. It consists of two angled posts with a horizontal crossbar at the top, forming an “A” shape. The squash vines can be trained to grow up the angled posts and over the crossbar.
  2. Cattle PanelTrellis: A cattle panel trellis is a heavy-duty option that can support the weight of large squash vines and fruit. It consists of a large wire panel that is anchored to the ground or a support structure. The squash vines can be trained to climb up the panel and over the top.
  3. T-Post Trellis: A T-post trellis is another sturdy option for growing squash vertically. It consists of one or more metal T-posts anchored in the ground, with horizontal wires or strings attached between them. The squash vines can be trained to climb up the wires or strings.
  4. Teepee Trellis: A teepee trellis is a simple and attractive option for growing squash vertically. It consists of several tall poles or bamboo stakes arranged in a circle and tied together at the top to form a teepee shape. The squash vines can be trained to climb up the poles and over the top.

Step 4 – Training butter squash on trellis

Training a butternut squash vine on a trellis is a great way to save space and keep your garden organized.

Once the butternut squash vines have grown to about 6-8 inches long, gently guide them towards the trellis. Use plant ties or twine to loosely attach the vines to the trellis. Make sure not to tie them too tightly, as this can damage the vine.

As the butternut squash vine grows, continue to guide it towards the trellis and wrap it around the mesh or grid. Encourage the vine to grow vertically instead of horizontally. Use plant ties or twine to loosely attach the vine to the trellis as needed.

To encourage healthy growth and fruit production, prune the butternut squash vine as needed. Remove any damaged or diseased leaves or stems, as well as any suckers that are growing from the base of the plant.

Conclusion – How to Grow Butternut Squash in Small Space?

In conclusion, growing butternut squash in a small space is not only possible but also easy and rewarding. By using trellises, containers, and compact varieties, you can enjoy the taste of fresh, homegrown squash even if you have limited garden space.

Whether you’re a city dweller or just looking to make the most of your backyard, these three methods will allow you to grow butternut squash with ease. So why not give it a try and enjoy the satisfaction of growing your own food?

Butternut Squash History

Butternut squash is believed to have originated in the region that is now Mexico and Central America, where it was first cultivated by indigenous peoples over 10,000 years ago.

The squash was then introduced to North America by early Native American tribes, who were known to cultivate and consume this vegetable.

The name “butternut” was first used in the early 1940s, and it is believed to be a reference to the squash’s buttery texture and nutty flavor.

Habitat

Butternut squash is a warm-weather crop that is typically grown in temperate regions around the world. The plant prefers full sun and well-drained soil that is rich in organic matter. It can be grown in a variety of habitats, from backyard gardens to commercial farms, as long as the growing conditions are suitable.

In terms of geographic regions, butternut squash is commonly grown in North America, Europe, Asia, and Africa.

In the United States, it is grown primarily in the Midwest and Northeast regions, where the climate is suitable for its growth. In other regions around the world, the plant may be grown in different seasons depending on local climate patterns.

Is Butternut Squash a Hybrid or True Variety?

No, butternut squash is not a hybrid variety. It is an open-pollinated variety, meaning that it can be grown from seed and will produce offspring that are true to the parent plant. This distinguishes it from hybrid varieties, which are created by crossing two or more different parent plants to produce offspring with specific traits.

However, there are some variations of butternut squash that have been developed through selective breeding. For example, some butternut squash varieties have been developed to be more resistant to diseases, or to have a higher yield. These variations are still considered open-pollinated, as they can be grown from seed and will produce offspring that are true to the parent plant.

Butternut Squash Physical Attributes

Here are some physical attributes of butternut squash:

  • Shape: Butternut squash has a bell-like shape, with a bulbous end and a narrow, cylindrical neck. The shape is often described as resembling a bowling pin or a vase.
  • Size: Butternut squash can range in size, but typically measures around 10 inches in length and 4-5 inches in diameter at the widest point. However, some varieties may be smaller or larger than this.
  • Skin: The skin of this squash is smooth and hard, with a pale, tan color. It may have a slight gloss or sheen to it. The skin is thin and easy to peel.
  • Flesh: The flesh is a bright orange color, with a smooth, creamy texture. It has a sweet, nutty flavor that is similar to pumpkin or sweet potato.
  • Seeds: Inside the hollow cavity of the squash, there are seeds that are surrounded by stringy, fibrous flesh. The seeds are flat and oval-shaped, with a cream-colored outer shell.
  • Weight: The weight of butternut squash can vary depending on its size, but typically ranges from 2-4 pounds.
  • Stem: The stem of the squash is hard and woody, and is typically several inches long. It may be left intact when the squash is harvested, or it may be trimmed off.

Butternut Squash Growth Stages

Butternut squash plants thrive in warm temperatures, with optimal growth occurring between 70 and 90 degrees Fahrenheit (21 and 32 degrees Celsius).

The plant can tolerate some drought, but consistent moisture is necessary for proper growth and fruit development. It is also important to provide adequate space for the vines to spread out, as the plant can grow up to 15 feet long. Thus, it is better to grow outside on the ground or use alternative ways to grow in small space.

1.      Germination

The first stage in the life cycle of a butternut squash plant is germination. The seed is planted in warm, moist soil, and typically takes 5-10 days to germinate. During this stage, the seed sends out a root and a shoot, which eventually emerge from the soil surface.

2.      Seedling stage

The seedling stage begins when the seed has germinated and the sprout has emerged from the soil.

During this stage, the butternut squash plant is still small and delicate, with only a few sets of leaves. The seedling stage typically lasts for about 2-3 weeks, depending on growing conditions.

Make sure to provide the seedlings with plenty of light, warmth, and moisture to ensure healthy growth. Once the seedlings have grown to about 3-4 inches tall and have developed their first true leaves, they are ready to be transplanted into larger pots or directly into the garden.

3.      Vegetative growth

The vegetative growth phase in butternut begins after the seedling stage, when the plant has developed its first true leaves and starts to grow vigorously.

During this phase, the plant will focus on developing a strong root system and growing lots of leaves and stems. The vegetative growth phase typically lasts for about 4-6 weeks, during which time the plant will grow to its full size and develop a sprawling, vine-like habit.

Provide the plant with plenty of space to grow during this phase, as well as regular watering and fertilization to support healthy growth.

Once the vegetative growth phase is complete, the plant will transition into the reproductive phase and start to produce flowers and fruit.

4.      Flowering stage

The flowering growth occurs after the vegetative growth phase, typically around 50-60 days after planting.

During this stage, the plant will start to produce large, bright yellow flowers. These flowers are typically large and showy, with five petals and a central stamen. They are also typically only open for one day, so it is important to watch closely for when they first appear.

The flowers are typically pollinated by bees or other insects, and once pollinated, they will begin to develop into fruit.

In some cases, the plant may produce male flowers before female flowers, which can delay fruit production. This is a natural process and should not be a cause for concern, as the plant will eventually produce both male and female flowers.

Continue providing the plant with adequate water and nutrients to support healthy flower development and fruit production.

5.      Fruit development

The fruit development growth stage begins after successful pollination of the flowers. The ovary of the flower develops into the fruit, which will continue to grow and mature over the course of several weeks.

During this stage, provide the plant with regular water and nutrients to support healthy fruit development. The fruit will typically start out small and green, and gradually grow larger and turn a light tan color as it matures. Also monitor the fruit closely to ensure that it is developing properly and not being attacked by pests or diseases.

Once the fruit has reached full maturity, it can be harvested and stored for later use.

The timing of the harvest will depend on the variety and growing conditions, but in general, the fruit should be allowed to fully mature on the vine before being picked. A mature squashes will have a hard, tough skin and be difficult to pierce with a fingernail.

Overall, the fruit development growth stage can take anywhere from 70 to 100 days, depending on the growing conditions.

6.      Harvesting

The harvesting stage occurs once the fruit has reached full maturity and is ready to be picked. Butternut squash is typically harvested in the fall, once the fruit has reached its full size and turned a light tan color.

In general, it is best to harvest the fruit when it has reached its full size and the skin has turned a light tan color, but before it starts to develop any soft spots or signs of decay.

7.      Storage

Proper storage of butternut squash is important to ensure that the fruit stays fresh and edible for as long as possible.

To store, choose a cool, dry place with good air circulation. The ideal temperature for storage is around 50-55°F (10-13°C), with a humidity level of around 50-70%. This could be a pantry, root cellar, or even a garage or shed.

Before storing, inspect the fruit carefully to make sure that there are no soft spots, bruises, or other signs of damage. Damaged fruit should be used immediately or discarded to prevent the risk of spoilage.

To store the fruit, place it in a single layer on a shelf or table, making sure that each fruit has plenty of space around it for air to circulate. Avoid stacking the fruit or placing it in a tightly packed container, as this can increase the risk of spoilage.

Check the fruit regularly during storage to make sure that it is still in good condition. Remove any fruit that shows signs of decay or spoilage, as this can spread to other fruit and cause it to spoil more quickly. With proper storage and care, butternut squash can last for several months, making it a great option for winter storage and use.

How to Grow Butternut Squash on the Ground [5 Tips]

By Sarwat Rehman

Growing butternut squash (a warm-season winter squash) on the ground is a simple and fruitful way of producing squashes at home. There is no expertise required. All can be done with proper planning and the right strategy of choosing the ideal location, preparing it for plantation, and finally, sowing the seeds.

This article will help you cover all these steps with a practical guide and post-plantation care for massive butternut squash harvest. Lastly, you will get 5 must-follow tips to grow butternut squash fast on the ground. So without any further delay, let’s get in!

Best Time to Grow Butternut Squash on the Ground

The best time to grow butternut squash on the ground is when the normal daytime temperature is above 75oC, and the soil temperature ranges between 65 to 70oC.

This winter squash does not like cold; frost or low temperatures can hinder plant growth. Thus you can start indoors by sowing seeds in early April and planting them out in late May.

On the other hand, if your climatic conditions are warm enough, you can directly grow butternut outdoors in late May and early June.

Growing Butternut Squash on the Ground – Step By Step

Growing butternut squash needs a bit of preparation and planning on your end. When it is the right time in your zone, follow the steps described below for a plentiful harvest at your place.

Step 1: Selecting a Plot or Garden Site

The first step in growing butternut squash on the ground is selecting the best plantation site. You cannot randomly pick a place and grow this plant.

Here are the 4 considerations you need to keep in mind while selecting a site to grow this winter squash variety:

  1. Butternut squash needs plenty of sun, so the best bet is to go for a location receiving at least 6 hours of direct sunlight.
  2. The magnitude of the plantation site depends on your need or availability of land. But remember, each butternut squash can grow 20 to 30 cm long or even more, and multiple fruits can crowd the space. Thus always consider the size of the land too.
  3. Also, don’t select a site with a previous history of powdery mildew, beetle infestation, or similar pests. These nasty pests will kill seeds before germination.
  4. Lastly, make sure the soil is well-draining and organically rich. Preparing the site (as described in the next section) will also be great before directly diving into the plantation stage.

Step 2: Preparing Plantation Site

All lands are not equally ready for plantation – they need soil analysis, organic treatments, and other stuff for ideal growth.

Here is how to prepare your backyard or kitchen garden area:

Soil pH Test

Checking soil pH is one of the first steps of this project, as the soil pH varies in different gardens. In fact, you will see a pH difference in the soil of the same garden due to fertilizers and other factors. Therefore, check the soil pH with the kit or send the soil sample to your local extension for in-depth analysis.

Always consider the fact that butternut squash ideally grows in acidic soil (between a pH of 5.8 and 6.8), so make sure the pH of your plantation site is acidic.

You can also adjust soil pH with home treatments without using harmful chemicals.

Organic Soil Treatment

The next step in preparing the soil for butternut squash plantation is organic soil treatment because the plant grows well in heavier soil.

Add well-rotted manure or compost, and be cautious; using aged manure is the best approach. Fresh manure may contain harmful bacteria and increase weed problems.

Another benefit of organic matter is you may not need additional fertilizers. Organically rich soil also helps in the uptake of water and nutrients.

Soil Setting

Blend the soil well after adding organic matter for uniform soil composition. Also, remove foreign bodies, including rocks and roots of previously grown plants.

Rake the soil smooth and loosen it for improved aeration.

At the same time, do not let the soil dry. Water appropriately without making it drenched.

The last step (optional) in preparing the site for butternut squash is making ‘Hills’ of the soil. The soil is mounded slightly to allow good drainage.

Hoe the soil into hills 7 to 10 inches high and 3 to 5 feet in diameter with 4 to 5 feet row spacing.

You can skip making mounds and continue plantation on flat ground if the soil is well drained and supports vine growth.

Step 3: Growing Butternut Squash on Ground

Till this step, your garden site has been selected, prepared, and ready for butternut squash growth. Just follow a few more steps, and you will finish the plantation. These are:

  • Take 2 to 3 butternut squash seeds and sow 1 inch deep in the loosened soil. If you plan to sow more seeds, like 4 to 5 per row, you must thin them. It is proven from research that increased plant density may result in a more significant number of smaller fruits. It is best to thin plants for your size preferences, and it is possible when seedlings show 1 or 2 true leaves.
  • You can start plants indoors for an early butternut squash crop before planting in warm soil. Indoor setup needs to be done 3 to 4 weeks before outdoor planting. For instance, if early May is your outdoor plantation month, you must start seeds indoors in early to mid-April.
  • Sow 3 to 4 seeds per 2 to 3 inches wide container (peat pots are recommended). Wait for the seedlings to appear and remove all except the healthiest one by pitching or cutting (but do not pull out). Now harden off young plants before transplanting them in the soil and gradually acclimate to the outdoor sun.

That’s all! Now you are done with the plantation. Wait and see what needs to be done (in the next section) for healthy butternut squash yield.

Keep Growing Squashes Healthy: Things to Do!

Here are the key things that need to be followed after planting butternut squash on the ground:

1.      Watering Plan

Regular watering is essential after setting seeds or transplanting butternut squash in the ground. It could be either rainfall or irrigation, but uniform watering is the key to healthy growth.

You can use drip irrigation or a soaker hose so that the leaves stay dry. Avoid overhead sprinkler irrigation for butternut squash as it may rot leaves and fruits.

Also, remember, sandy soils require more frequent but less water applied at any one time.

2.      Feeding or Fertilization

Butternut squash is a heavy feeder and requires lots of nutritional energy to produce quality squashes.

Organic matter added before the plantation also does the same job and provides nutrients, but additional fertilization is required when seedlings are a few inches tall.

Fertilization at this stage will help the plant (butternut squash fruits) to grow bigger. Once the squashes grow bigger, avoid adding more fertilizer until after the blossoms appear.

The two types of fertilizers for butternut squash include:

  • Granular
  • Water soluble

You can use either depending on your ease or availability. Good quality, well-balanced granular fertilizer (10-10-10) does well for butternut squash while young. Then use a fertilizer low in nitrogen, which encourages excess vine growth and suppresses fruit growth.

3.      Mulching

Mulching is a great way to conserve moisture and maintain soil temperature. It also keeps fruits from direct contact with the soil, where diseases could infect them.

You have two options for mulching butternut squash:

  1. Organic mulch
  2. Plastic mulch

Pine straw or wheat straw is used as organic mulch.

On the other hand, butternut squash grown on the ground could also be cultivated with black plastic mulch. The black plastic absorbs heat allowing the soil to warm quickly and is best for areas where the soil temperature is hard to raise.

5 Tips to Grow Butternut Squash Fast

  1. Make a flexible watering plan for butternut squash per your climatic conditions. For instance, the soil in warmer areas dries quickly, so water it more during the dry period. On the contrary, limit watering on rainy days to prevent leaching.
  2. Get the benefit of online apps for a reminder of watering time to avoid delays or overwatering. These apps also keep track of your watering schedule and give suggestions for particular zones.
  3. Generally, 100 to 120 days (3 to 4 months) is the butternut squash maturation period. Ensure to take care of the plant with proper feed and water until the fruits are ripe.
  4. Growing weeds with butternut squash vine is normal. You need to get rid of them by hand pulling or shallow cultivation.
  5. Organic materials such as chopped-up leaves, grass clippings, and straws can be tilled under at the end of the growing season, adding nutrients to the soil for the following year.

Conclusion – How to Grow Butternut Squash on the Ground?

Butternut squash is a vine, typically growing on the trellis or wall with fruits facing down, but growing it on the ground is manageable.

You just have a good patch of land receiving at least 6 hours of sun. Make it ready by removing rocks, weeds, and roots.

Loosen the soil and sow seeds the way directed above in the plantation section. Next, plan post-plantation care and see what type of fertilizer and mulch suits your land the best. Carefully working on all the steps will result in a massive butternut squash harvest that you can cook, bake and even store for later delicious treats.

White Spots on Tomato Leaves – 7 Main Reasons + Treatment Plan

By Sarwat Rehman

Seeing white spots on tomato leaves can be concerning for any gardener who has spent months growing the plant, waiting to harvest those beautiful red tomatoes- but what causes these patches?

White spots on leaves are caused by several reasons, including sunburn, insect bite, frostbite, nutritional deficiencies, mold growth, and a fungal disease called powdery mildew. All of these negatively affect the health of your plant and need a prompt treatment course.

Most plant issues can be cured by addressing the root cause and preventing further damage. In this article, we’ll discuss all these problems and their treatments, so your plant remains healthy and grows gorgeous plump tomatoes.

Main Reasons of White Spots on Tomato Leaves – Treatment

white spots on tomato leaves
Tomato Plant Problems

1.      Sunscald

Sunscald or sunburn is a common occurrence when plants are exposed to harsh sunlight for extended periods. Tomato, or any other vegetable leaves, can get sunburnt fast if planted directly under the sun. It’s a mistake a lot of beginner gardeners make- even though tomato plants thrive in the sun, more sunlight is not always necessarily better.

Sunburnt leaves often have white slivers in their center but can appear as patches. It’s more common in young plants and seedlings.

Leaves also look scrunched up when they’re sunburnt, so if you notice an abundance of white and faint green with a wilted-looking leaf, sunlight is the likely culprit. Another way to diagnose a sunburnt plant is by looking at the tomatoes- they will likely have blisters and burns.

In addition to bright sunlight, sunburn can be caused by a sudden change in the plant’s location. Moving a plant usually kept indoors that gets filtered light under the intense sun for a prolonged period can also cause leaves to turn white.

How To Treat It:

Sunburns don’t go away, but they don’t affect healthy plants much. Tomato plants need about 6-9 hours of sunlight a day. Too little and fungus may grow, too much and sunburn may occur. To avoid sunburn blisters, install a shade that allows light to constantly filter through while direct exposure is available for a few hours daily.

If you’re introducing a plant to sunlight, make sure to do it gradually, so the plant has time to adjust instead of a radical change. Plants hate getting blasted by heat and light, no matter how important they are.

2.      Insect Bite

If you’ve found tiny white spots on tomato leaves that are scattered and look cloudy, it may be a stinkbug bite. Stinkbugs don’t attack the leaves only, though, and you will likely find similar spots on the fruit as well.

Other bugs like thrips, spider mites, and aphids might be causing these spots. However, they’re never as active as stinkbugs. Stinkbug bites can also be distinguished by their presence under the leaf and below the tomato’s skin.

How To Treat It:

Insect bites don’t spread, so your only focus should be keeping the bugs away. Instead of buying an insecticide, you can use something like Neem oil or dichotomous earth. A sharp mulch also keeps bugs at bay.

3.      Frostbite

On the other end of the spectrum of sun and heat damage is frostbite. If you live in a cold climate where temperatures can drop well below 5C (40F) in winters, unprotected plans exposed to the atmosphere can get frostbites quickly.

Thankfully, frostbites are never too detrimental to your plant’s health and can be easily spotted. Tomato leaves get frostbite near the vein, where they initially appear white but then turn tan or brown. White ice crystals line the leaves, and the stems appear sunken too. Younger plants are more vulnerable to cold.

White Spots on Tomato Plant

How To Treat It:

Frostbite is cured by raising the temperature. You can do this by watering them (yes, it sounds counterintuitive, but it works), providing a covering at night, and using mulch. Also, a little tip is not to prune the plants until temperatures get warmer. That way, the new foliage and growth isn’t affected.

4.      Nutritional Deficiency

An important deciding factor for a plant’s health is the kind of soil and fertilizer you use. Fertilizers and mulches are crucial for a plant to remain healthy and grow those Instagram-worthy tomatoes.

Using a fertilizer that doesn’t fulfill a plant’s nutritional needs can cause its leaves and stem to show white and faint yellow spots. Patchy leaves may be a sign of deficiency of essential minerals like magnesium, potassium, calcium, nitrogen, and phosphorus.

How To Treat It:

Nutritional deficiency can be treated using compost or fertilizer with a balanced nutrient supply. Fertilizers with both nitrogen and phosphorus base are better. Magnesium deficiency can be addressed by using Epsom salt. Calcium can be added by powdered lime mixed with soil. A good source of potassium for your compost is kelp.

5.      Leaf Mold

If the white blotches on your tomato plant leaves are not due to weather, insects, or nutrition, then it’s likely a disease.

One of the most common diseases blighting tomato plants is the tomato leaf mold, caused by a fungus called Passalora fulva, which affects thousands of plants worldwide. It’s mostly present in greenhouses, though it can spread in any climate with high humidity.

Leaf mold can be observed as faint white-yellow patches when the mold is not at the sporulation stage. Once it starts spreading by spores fast, the white often turns brown. In severe cases, it can even affect the fruit. Hence it’s a disease that needs to be addressed quickly.

How To Treat It:

Leaf mold can be treated by pruning affected leaves and using a simple fungicide. Exposure to a good amount of air and sunlight can also treat the issue on its own.

6.      Powdery Mildew

Another cause of tomato plant white leaf spots is powdery mildew, another type of fungal disease. These are the most distinctive white spots that appear as round white blotches. If they persist for a long time, they leave dead tissue behind, turning leaves brown and causing them to wilt.

Powdery mildew is brought by wind and grows at accelerated speeds in high humidity and shady, moist environments. Plants that receive little to no air or sunlight can also be affected by mildew. Consistent mildew growth is facilitated by excessive use of fertilizer and overwatering.

Powdery mildew isn’t known to harm plants significantly, though, and your plant will most likely live. However, it can affect the flavor of tomatoes and significantly reduce your yield.

How To Treat It:

Powdery mildew has two steps to treatment. First is pruning- make sure to get all affected areas removed and properly sanitize your equipment. If more than half the leaves are affected, remove the most severe ones only so your plant can survive.

Second, use a sulfur spray to deter powdery mildew growth quickly. A good home remedy for white spots on tomato leaves caused by mildew is a milk spray- simply mix milk and water in a 2:3 ratio and spray it everywhere. Using Neem oil and vinegar also works.

7.      Late Blight

The last cause of white spots on tomato leaves is late blight. Late blight is also a fungal infection that starts as white spots but is actually a very severe disease. It spreads very fast and causes leaves to turn brown, shrivel up, and die. It also causes dark brown spots on tomatoes and spreads to nearby plants like wildfire.

How To Treat It:

If you spot late blight on tomato, immediately prune the affected parts and discard them. Any leaf or fruit affected will not recover. Do not use pruned parts in compost. Do not bring them in close vicinity to any plant, or late blight will also affect them. Sanitize your pruning tools thoroughly.

Once you’re done pruning, use a fungicide containing copper, maneb, mancozeb, or chlorothalonil. Do not water near the area affected by late blight. Use the fungicide once or twice a week on all plants.

Prevention of White Spots on Tomato Leaves

Now that we’ve addressed all the main reasons why white spots might appear on tomato leaves and their treatment, it’s time to discuss some general measures gardeners should take to avoid all of these issues.

1.      Proper Watering of Plants

Overwatering plants is a leading cause of plant death and promotes fungal growth. Water plants appropriately, depending on humidity and plant size. Don’t water the leaves directly, especially if you’ve dealt with fungus recently. Tomatoes need about 1 gallon (4.5 liters) of water per week.

2.      Using Mulch

Mulch is essential for proper plant growth. It protects against fungus and pests, retains water, and provides beneficial nutrients. It’s also great for thermoregulation by the plant.

3.      Ensuring Air Circulation

Tomato plants must be 1.5-2 feet apart to ensure proper air circulation. Make sure the plant is not in a confined spot, and there’s not a lot of moisture nearby; otherwise, molds could take over.

4.      Pruning

Regularly pruning wilted parts of the plants can help your plant grow faster and healthier. You should also prune any parts that seem infected (yellow or white spots). Just don’t prune during winters, as your plant can’t grow new foliage when in survival mode.

5.      Rotating Crops

Crops need to be rotated every year or two, and tomatoes are no different. After two spring seasons, you should rotate your tomato crop to avoid weed growth and insecticide-resistant pests. Do not use seeds from infected plants either.

Conclusion – White Spots on Tomato Leaves

There are several reasons why white patches might appear on tomato plant leaves. However, they’re easy to identify and treat using simple measures, like shielding your plant from excessive sunlight, avoiding overwatering, and using quality mulch and fertilizer. Even if your plant is diseased because of fungus, you can save the crop by pruning and using fungicides.

As long as you tend to your plant regularly and notice symptoms like white spots on leaves early, you can protect your plant from damage and wilting.
