Most vegetables require full sun to thrive, yet space in a backyard garden may be limited by trees, structures and other factors. Companion planting — pairing veggies with plants to repel pests or choke out weeds– can maximize productivity of your garden and help increase yields.
Peas
Peas and beans belong to the legume family of vegetables, known for their ability to fix nitrogen in the soil symbiotically by working with bacteria present in the soil to convert atmospheric nitrogen into forms other plants can absorb without needing chemical fertilizers; additionally, legumes improve soil structure. They thrive with most vegetables and herbs alike but especially thrive alongside tomatoes, carrots, radishes, kohlrabi cucumbers sweet corn. Although not ideal, onions and garlic have allelopathic properties which inhibit their growth as legumes do!
Pea vines pair well with nasturtiums and marigolds to deter garden pests while encouraging pollination. Cucumbers, dill, and rosemary also make excellent companions to pea vines; cucumbers especially enjoy shade from dill’s dark shade while the strong scent of rosemary repels cucumber moths and other pests, while herbs such as dill attract natural insect pollinators to keep cucumbers thriving.
Carrots make excellent companion plants with fast-growing radishes and turnips or slow-germinating peas, but should be planted separately from cabbage family members such as broccoli or Brussels sprouts. Carrots work particularly well when planted alongside aromatic herbs like dill, parsley and chives; also great with peas, Swiss chard and spinach but should be planted away from kale and collard greens which compete for soil nutrients; pair well with tomatoes and pepper plants while planting alongside leeks to deter carrot flies!
Carrots
Carrots thrive best in cool, rich soil with plenty of organic matter, with long seasons requiring constant care with regards to germination and soil moisture levels. Unfortunately, carrots are vulnerable to root maggots and carrot flies as well as quickly turning bitter without proper irrigation.
As biennials, carrots flower and set seed in their second year. This requires considerable energy from the plant, making it unsuitable for succession planting with fast-growing crops like radishes that compete for nutrients with them. On the bright side, however, carrots will tolerate cold winter temperatures if planted under a row cover to provide extra insulation.
Carrots should be grown among crops that share space effectively and mutually benefit each other’s presence, such as leafy greens such as lettuce and spinach; leafy herbs like chives and chervil (which repel aphids); onions (whose fungicidal aroma wards off carrot flies); leeks; as well as flowers such as nasturtiums, marigolds or daffodils which discourage rodents from damaging roots.
If you’re cultivating carrots in containers, the key to successful cultivation lies in using an open and free-draining potting mix that drains well and stays moist but never soggy – aim for 12 inches of sandy loam soil free of debris and compactions – since carrots are slow feeders they need light irrigation regularly but without saturation to remain healthy and fork free. Compost and organic material preparation is also highly recommended prior to planting as this will protect them against disease risk.
Lettuce
Leaf lettuce’s shallow roots make it an excellent companion crop to other crops such as peas, carrots and onions in your garden, keeping pests at bay from other vegetables such as beets and spinach. Furthermore, peas provide additional nitrogen for healthy soil in which to grow lettuce, carrots, radishes and cabbage all grow together well together; lettuce also thrives near kohlrabi turnips and carrots!
Lettuce requires plenty of nitrogen for its tender leaves to develop fully, so be sure to fertilize it throughout the growing season using a liquid such as Miracle-Gro(r) Performance Organics(r) All Purpose In-Ground Soil or Miracle-Gro(r) Performance Indoor Container Mix that contains nitrogen-rich solutions.
If you’re growing broccoli, heat-tolerant leaf lettuce planted around its base can provide additional shade to block out weeds and ensure maximum sunlight without scorching during hotter periods. This will allow your broccoli plants to receive maximum sunlight without burning under summer heat conditions.
Herbs make excellent companion plants in vegetable gardens, helping repel weeds while improving soil conditions. Mint, chives and garlic repel aphids and other pests that attack various vegetables while others such as thyme basil marigolds can attract beneficial insects – providing natural solutions while encouraging productive environments.
Beans
Beans are known for adding nitrogen to the soil, so they pair perfectly with carrots, beets, corn, lettuce, spinach and Swiss chard as nitrogen-fixers. Furthermore, beans pair nicely with squash, sunflowers and tomatoes. Onion relatives such as chives can interfere with one another’s growth while deterring beneficial insects from visiting your garden.
American Indians created the “three sisters,” an arrangement consisting of corn, beans and squash known for providing shade as well as moisture retention and blocking out weeds. With some creative thought and application of this model to other crops – for example tall corn plants can serve as good supports for climbing beans without fear of their stems rotting – while adding nitrogen into soil while deterring pests like cucumber beetles or tomato hornworms from getting too close.
Aromatic flowers make an excellent companion for many vegetables, both deterring some pests and helping attract pollinators. Nasturtiums and marigolds, for instance, have proven particularly useful at repelling aphids, squash bugs, cabbage moths, carrot flies and potato beetles; Scabiosa, Thyme Chamomile and Sage Cilantro repel the cauliflower Moth; while for optimal results choose blooming plants that bloom around the same time as your vegetables – many seed packets list recommended planting dates/blooming periods as well as sun/water requirements for optimal results.
Radishes
Radishes (Raphanus sativus) are quick-growing root vegetables that can often be harvested within four weeks of being planted. Prefers cooler environments, they make an ideal partner to peas and carrots as both require high amounts of nitrogen for proper growth; additionally planting them directly alongside peas or carrots gives double crops!
Radish greens make an irresistibly crunchy addition to salads and slaw, or can even be sauteed or stir-fried before being pickled for pickle relish! For optimal radishes, plant them in well-draining soil that’s rich with compost or organic matter; to maximize flavorful results, space out plants 2.5cm apart at least.
Radishes thrive when planted among other members of the Brassica family, such as arugula, broccoli, cabbage, kale, collard greens, turnips, mustard and rutabagas. Radishes may be used as trap plants alongside onions to deter root maggots; just ensure there’s adequate drainage if doing this in a garden or raised bed – otherwise they’ll quickly rot! They may also help repel pea aphids which become prevalent during spring and summer; to reduce this risk further it’s important that clean soil is used along with sanitized tools when planting! Radishes may also help deter pea aphids which become common during this time period – to reduce this risk use only clean soil when planting them so ensure there’s plenty of drainage while doing so to reduce risk when planting your seedlings! To reduce this risk when planting make sure use clean soil as well as using clean tools when planting your seedlings when planting your seeds – to decrease risk a fungal disease this way radishes are more vulnerable when planting than using clean tools when planting your seeds when planting so ensure sanitized tools when planting for best results when planting! To reduce risks from damping off damping off disease it is advised that when planting which means using clean soil and tools when planting which helps ensure young seedlings will also reduce risks from damping off, damping off make sure use clean soil along with using clean tools sanitized tools when planting your seeds so this way ensure sanitized tools during seedlings are at risk and using clean tools sanitized tools when using clean soil and tools as this way when using clean tools when planting when doing your seedlings can killing off diseases occurrence. To reduce risks use clean soil as this disease may kill young seedlings use use clean tools when planting your young seedlings sanized before making sure soil and tools when planting your sanits need not becoming damping off occurring when seedlings should also used when using clean tools before placing.
Tomatoes
Tomatoes tend to grow well alongside most vegetables, but there are a few key considerations you should be mindful of as you cultivate your garden. Tomatoes need ample sunlight and warm soil in order to thrive; if your garden is located in a shaded spot, plant some sun-loving herbs or flowers alongside the tomatoes as this may block out some of their light requirements while providing wonderful fragrance while you tend your plot.
Tomato plants are susceptible to many different kinds of diseases and pests, making it essential that they’re planted near other vegetables that will provide support. If disease resistance is your main priority, opt for varieties like Valentine or Yellow Pear that resist blight; alternatively, less popular types like Silver Queen could produce unique oblong shapes with minimal maintenance needs.
Companion planting is a tried-and-tested strategy for mitigating pests, increasing harvests and enriching vegetable flavor. Implementing companion plants into your vegetable garden could be as easy as adding basil, oregano or another herb known to repel insects that harm tomato crops – including borage which attracts wasps that lay parasitic eggs on hornworm caterpillars for added pollination and natural insect pest control!
