Vegetables – Broccoli Companion Plants
Beet plant (Beta vulgaris) is a cool-season fast-growing vegetable plant that grows well in cool temperatures of spring and fall 1.
The beet plant is generally grown as a root crop, but all parts of it are edible. These are one of the most beneficial companion plants for broccoli as they require little room and are compromising.
Beets also enrich soil nutrients and make it healthy for companion planting. The second most obvious reason for planting beets with broccoli is the calcium need.
Broccoli absorbs an enormous amount of calcium from the soil that does not affect beet growth. In this way, both plants get what they need without any competition and prove good companion plants for each other.
Lettuce (Lactuca sativa) is a well-known leafy vegetable and, like beet plants, is also a cool-season crop. It is grown worldwide, but the USA and Europe are the most significant consumers and producers of lettuce 2.
Growing lettuce with broccoli is in both plants’ best interest and provides grow-able conditions to each other. You can plant relatively close to each other without worrying about space and nutrients as both plants have root systems at different levels and draw nutrients from different levels of the soil.
So, there is not any stressful situation or unhealthy competition among plants. In fact, lettuce has a fibrous root system that makes roots go deep down in the form of fibers and absorb required nutrients.
There is also a mutual benefit of growing lettuce with beets and broccoli, as lettuce benefits from the magnesium added by the beets.
So, it’s a win-win situation for all plants.Potatoes
Potato plant (Solanum tuberosum), member of the nightshade family Solanaceae is staple food crop of many countries 3.
Potatoes are grown for edible tubers widely used all over the world. You may cut, mash, boil or cook potatoes to have a starch-rich diet. In fact, potato flour is also used as a thickener for sauces in baking.
If you already have potatoes in a garden bed, you must know how easily they grow. But growing potatoes with broccoli is an ultimate treat.
They make broccoli more delicious and mouthwatering by enhancing its flavor. You can clearly notice the difference between broccoli having potatoes as a neighboring plant and the one growing alone.
Secondly, growing potato plant along with broccoli is also a favor to your potatoes. Broccoli has a shallow root system and doesn’t need in-depth nutrients. On the other hand, potatoes have a deep-rooted system, and roots anchor profound in the soil to absorb nutrients.
So, both plants reasonably get the required nutrients at different levels of the soil without developing competition.
Shallots, a variety of onions (Allium cepa), are slightly aromatic plants belonging to Amaryllis 4.
The shallot bulbs are grown for their mild flavor in predominantly Asian cuisines. You can also use shallots in meat recipes and different sauces.
When it comes to broccoli companion plants, shallots stand out for pest repelling capabilities. They repel carrot rust fly and make vegetable garden pest-free.
Similarly, you can pair shallots with other veggies like carrots, beets, and herbs, including sage, thyme, mint, and chamomile.
Radish (Raphanus sativus) is a cool-season, fast-growing vegetable belonging to the mustard family. The most common radish varieties are likely of Asia and are grown worldwide 5.
You can eat raw radish roots or cook leaves for a mild crisp.
If grow spring-type radish, they begin in late summer and mature in cooler days of fall. In comparison, winter radishes are sown in mid-summer to late summer and grow considerably more prominent.
A considerable benefit of rowing radish with broccoli is its mild growing behavior. Radishes do not thrive. They mature before other crops and help break up the soil as they grow. This early radish growth breaks down nutrients in the soil take companion plants can take.
You can also interplant broccoli with radish, spinach, and lettuce. These crops enjoy the shade under broccoli during late spring and early summer.

Mint also adds a unique flavor and pleasant aroma to the salads and cuisines. There are over 25 species of fragrant herbs, including this mint family 10.
Mint is a fantastic broccoli companion plant as it helps to maintain the fertility of the soil. It attracts earthworms, natural soil dwellers to improve soil fertility and helps to establish a uniform nutrient level in the soil.
Similarly, mint attracts hoverflies and predatory wasps and repels flea beetles, aphids, and cabbage moths. You can use cut mint as mulch around broccoli or grow in containers around any vegetable garden.
Dill (Anethum graveolens), a parsley family member, is an annual or biannual herb with a strong scent 11.

What not to Plant with Broccoli – Bad Broccoli Companion Plants
When growing broccoli companion plants, avoid other members of the brassica plant family as they prove bad companions in poor soils 15.
Plants from the same family have similar nutrient requirements, and in nutrient-deficient soil, plants compete and grow with nutrient deficiencies.
Growing different brassicas is not harmful as plants have a large nutrient reservoir if the soil is nutrient-rich and fertile. Also, be sure to properly fertilize the soil, so the soil remains full of nutrients throughout the growing season.
Here are some plants, including Brassicas that are avoided to plant with broccoli:
- Mustard greens
- Pole beans
- Lima and snap beans
The other significant category of bad broccoli companions is the heavy-feeders. Broccoli is also a heavy feeder, and other heavy-feeding plants grown in broccoli’s vicinity can negatively affect it.
Instead, pair up broccoli with light-feeders, for example, beets or plants mentioned above in the article.
Here are some heavy feeders you must avoid to grow with broccoli:
- Sweet corn
So, it is all about broccoli companion plants, what to avoid and what to plant with broccoli. Hopefully, now you can better get the benefit of companion plantation and grow multiple plants to enhance the garden diversity.
