Most flower and vegetable combinations promoted for companion planting need more scientific support. Yet, many work effectively – for instance, marigolds repel cabbage worms while drawing bees to your garden, while garlic helps deter nematodes that damage roses.
Plant partners can improve soil quality, increase crop nutrition, provide shade, provide natural trellising solutions, and visually distract pests.
Root Vegetables
Root vegetables may appear as green stems snaking through the dirt. Still, their benefits go much deeper than that, from enriching soil quality and supporting healthy microorganisms to deterring pests – and being an integral component of companion planting strategies.
Gardeners find interplanting different crops together an easy and natural way to enhance the health of their gardens while simultaneously controlling weeds and pests. This ancient practice, which involves strategically pairing compatible plant species for increased crop yield or deterring pests, has been around for millennia – making organic gardening possible!
One such example is the three sisters model, a Native American planting technique that pairs corn, beans, and squash to benefit each other mutually. Corn provides structure while deterring pests; beans provide nitrogen while decreasing chemical fertilizer use; squash helps suppress weeds while maintaining moisture balance in its surroundings.
Root vegetables can be planted throughout a garden to increase production while providing numerous ecosystem services, including reduced soil compaction and better water retention. Carrots planted among radishes may help combat soil erosion by drawing nitrogen out from deeper levels in the soil while growing alongside onions, which can serve as visual deterrents against potential onion pests.
Other root vegetable interplanting examples include pairing kohlrabi with beets to prevent bolting and add sweeter flavours, pairing parsnips with rutabagas to attract beneficial insects that feed on nematodes and other harmful organisms, planting marigolds among tomatoes as a form of pest control to repel nematodes while simultaneously attracting predatory insects that reduce chemical pesticide usage. These methods all offer effective solutions!
With the rise of organic and sustainable agriculture, companion planting is increasingly seen as a strategy to maximize crop growth while decreasing reliance on chemicals. By mastering these time-tested strategies, gardeners at all levels can produce healthier gardens with minimal effort – something the From Seed to Spoon app makes even easier!

Legumes
Legumes–including peas, beans and lentils–make excellent companion plants, providing valuable sources of plant-based protein, resistant starch and healthful antioxidants. Legumes also fix nitrogen into the soil so other crops can access nutrients deeper down in the ground more readily; plus, they increase in any garden, so add them as part of your harvest rotation of produce.
Companion planting can help provide essential benefits such as increased nutrient absorption, natural pest control, enhanced soil fertility and pollination. Tomatoes and basil are effective because tomato plants release compounds to repel common pests, while basil attracts beneficial insects that benefit crop production. Meanwhile, lettuce and tomato also thrive together due to similar root depths, with tall tomato plants offering shade that keeps lettuce cool in its growth stage.
Native Americans made widespread use of companion planting, known as the Three Sisters system, consisting of corn stalks as natural trellises for bean vines, while rapidly growing squash provided a living mulch that suppressed weeds while conserving moisture. This time-tested practice is still influential today!
Successful companion planting requires an in-depth knowledge of each vegetable, its needs and interactions, and how its neighbouring crops interact. To optimize the results of companion planting, choose plants with complementary nutrient requirements and growth habits. For instance, peas and carrots can work very well together since peas fix nitrogen that carrots cannot access easily; in contrast, carrots provide calcium and potassium that legumes cannot easily access.
Understanding how each plant interacts with its environment – including pests and weeds – is also critical. Certain plants repel or attract certain insects, while others might harm nearby vegetables or interfere with pollination processes. To minimize this issue, rotating crops every season and closely examining plants is critical – remember to use organic solutions such as mulching and crop rotation instead of harmful chemicals!
Flowers
Integrating flowers, herbs, and vegetables into your vegetable garden is one of the best ways to address pest problems naturally and with natural solutions. Their mutualistic relationships can deter or eliminate pests while improving garden health and yields.
Some plant partnerships emit strong scents or chemical compounds that naturally repel pests, helping reduce pest populations without chemical interventions. A famous example is marigolds’ effectiveness at controlling white fly infestations in tomato gardens; other flowering crops like nasturtium and calendula can also provide effective companion plants in gardens to deter harmful insects.
Companion planting can also aid with pollination, an essential part of successful fruiting and vegetable growth. When certain flowers are planted with vegetables, their scents and pollen attract bees for pollination, increasing garden productivity while reducing chemical intervention needs in vegetable gardens.
Companion planting techniques aim to enrich the soil and promote optimal crop performance. Cover and green manure crops can help break up heavy clay soils, while legumes such as beans in the Three Sisters system provide essential nitrogen that grass crops can fix into their roots.
Along with specific companion planting techniques, general strategies can be implemented across garden beds and vegetable varieties. For instance, planting leafy greens such as spinach and beets between fast-growing vegetables like tomatoes or peppers can save space while offering shade that conserves moisture and conserves space for faster-growing veggies like tomatoes or peppers. Also, if you have a large container dedicated to salad gardening, try interplanting tomatoes, peppers, lettuce, and basil all simultaneously in one pot!
Herbs
Plantings can enhance their flavour by including herbs among vegetables and flowers while deterring pests, attracting beneficial insects, suppressing weeds and providing structural support (for instance,e, beans climbing up corn stalks). One herb, Neem (Azadirachta indica), can be sprinkled around vegetable plants to repel plant-eating bugs like aphids, whiteflies, carrot flies and cucumber beetles. At the same time, its oils protect them against root rot, fungal infections, and stem blights.
Planting herbs, legumes, and vegetables together is a great way to save space. For instance, planting radishes among tomatoes or peppers will cut watering costs while providing shade from their quick maturation. The same technique could also work well in large containers; an “oregano garden” might feature tomatoes alongside basil, oregano and peppers, all grown within one container.
Companion planting can help improve soil health, increase yields, and naturally control pests. Deep-rooted legumes can loosen compacted soil, while tall herbs serve as natural trellises for vine crops such as beans and peas. Furthermore, certain herbs, such as cilantro and mint, are known to attract bees, which pollinate vegetable crops to increase yields.
Companion plants themselves can help shield main crops from pests by emitting odours that deter insect predators, acting as visual distractions, or acting as “banker” plants to lure and feed beneficial insects that eat common garden pests; for instance, marigolds can effectively deter cucumber beetles and cabbage worms when planted radially adjacent to cucumber and cabbage beds, respectively.
Many plants also exert a subterranean impact by helping to improve soil structure or prevent soil erosion. For instance, squash works to break up compacted soil and to avoid weed growth, while kohlrabi’s deep-penetrating roots penetrate hard-to-reach areas for optimal drainage; potatoes’ deep roots penetrate compacted soil to release essential nutrients while squash’ broad leaves help break up compacted soil while breaking up compacted areas; while squash leaves work effectively at breaking it up compacted soil whereas squash’s broad leaves work effectively at breaking up compacted soil while squash leaves work effectively to break up compacted soil and prevent weed growth while interplanting nasturtium (Asteraceae) with potatoes reduced significantly the number of nematodes found in soil. One recent study demonstrated how interplanting between potato and Nasturtium (Asteraceae) significantly reduced the number of nematodes found.
