14 Best Tomato Companions

Companion planting is a major aspect of gardening, based partly on science and partly on customs. Some plants do well when planted together, and then there are also plants that shouldn’t be planted together. Tomato companions planting is a great way to get multiple benefits in one go.

Tomatoes are widely popular in home gardens, and it helps to know which plants work well with them. Other than improving growth and repelling pests, growing friendly plants together also helps you make the most out of the small space you have – something that urban gardeners will appreciate most.

Tomato companions

Different tomato companions offer different benefits. They enhance growth, provide more flavor to the fruit, assist pollination, and protect the tomato plant against pests and insects. Additionally, they bring diversity to your garden. 

Planting some additional friendly vegetables means you can bring more organic variety to your dinner table; planting flowers alongside tomatoes is a treat for the eye and also for the pollinators. 

Choosing the right plants to grow next to your tomato crop helps you make the most out of companion planting while choosing the wrong ones can do more harm than good. 

Vegetables as Tomato Companions

Peppers

All kinds of peppers are excellent companions to your tomato plant. Sweet and hot peppers do not benefit the tomato plant in particular, but since both types of plants belong to the nightshade family, they go along well in the same garden. Also, since both require similar care, and have similar sunlight and watering requirements, it’s simpler for you to tend to them in the same garden bed.

Lettuce

Planting lettuce or other leafy greens in the same bed as tomatoes benefits both the varieties equally. While lettuce benefits from the shade offered by the taller tomato plants, the tomato plant, in return, benefits from the moisture retention provided by lettuce. Lettuce serves as a living mulch for your tomato plants, holding moisture and keeping the soil cool. It also prevents the spread of diseases.

When growing Lettuce don’t forget to cover and protect from birds. This lightweight netting is perfect and sizable for most backyard plots measuring 13ftx 33ft.

Asparagus

Asparagus and tomatoes don’t only make the perfect combo for your salad, but also for your vegetable garden. When planted alongside each other, they offer mutual benefits.

They also prevent the growth of weeds, making sure that they are the only ones benefiting from the nutrient-rich soil.

Marigolds repel a variety of pests for tomatoes. They release chemicals that are especially effective in eliminating root-knot nematodes to prevent damage to your tomato crop. 

Calendula

Calendula is similar to marigold in appearance and grows well with tomatoes. However, it does not repel any insects for tomatoes, unlike marigolds.

Nasturtiums

Nasturtiums are usually planted close to tomatoes, offering a tempting alternative for pests like aphids to feast on, rather than your treasured tomatoes. Additionally, the leaves and flowers are edible – another colorful addition to your tomato salad. 

Tomato Companions For Achieving Different Benefits

Different companions can bring different benefits to your tomato crop. While warding off pests and insects is the major goal of gardeners when growing certain plants together, there are several other benefits that can be reaped out of companion planting. Intelligent plant combinations can improve soil fertility, improve pollination, encourage beneficial insects to counter pest attacks and ward off weeds. 

If you have certain goals in mind when deciding on plants to grow with tomatoes, here are some suggestions:

  • Tomato Companions For Pest Control

Pests are often a problem when growing these sweet, juicy vegetables. Thyme and basil are two herbs that you can plant around your tomato plants to deter pests. Research has found a reduction in egg-laying behavior of common pests like hornworm and armyworm when these plants are grown in the vicinity. Certain plants drive away pests from tomatoes by attracting them towards themselves and acting sacrificially. These include cowpeas, collards and radishes. Harlequin bugs, for instance, will rather go for collards than attack your tomatoes. 

  • Tomato Companions For Improved Pollination

Though tomato plants are self-fertile, help from bees and insects increases pollination even further. For a tomato crop, the presence of bumble bee population can be a huge blessing. Their vibrations can knock the pollen loose for improved pollination and better fruit set. Having flowering plants like sunflowers, beans, coneflowers and red clovers are some of the favorite plants of bumble bees and can increase their population in your tomato garden. 

  • Tomato Companions For Reduced Diseases

Fungal diseases are a common problem with tomato plants. Certain plants can help reduce diseases in tomato plants. Gardeners often grow a thick cover of sweet potato plants on the soil around the tomato plants. The dense cover prevents rain and irrigation water from splashing up the tomato stems, reducing the risks for many fungal diseases. Hairy vetch is an excellent cover crop to plant in the fall. Cut the plant short in spring and plant tomatoes through them. They will prevent splashes and reduce weeds to keep your tomatoes free of diseases.  

  • Tomato Companions for Beneficial Insects

Having beneficial insects around your tomato crop can help manage pests naturally. Growing plants like dill, fennel, cilantro and oregano welcomes a host of good bugs to drive away the bad ones. The blooms from these plants offer nectar and pollen for a variety of beneficial bugs, including lacewings, ladybugs, parasitic wasps and more. 

  • Tomato Companions For Weed Control

You can also grow certain tomato companions for minimizing weeds. Winter rye is a good cover crop to grow in the fall. At springtime, you can cut down the cover crop, and grow tomato transplants in its residue to reduce the possibility of weeds. Oats work in the same way. Crimson clover can be grown as a living mulch around the tomato plants to prevent weeds.remember to cut it back before they bloom and drop seeds.

Plants to avoid

Not all plants go along well with tomatoes. Some can harm your tomato crop; remember to plant them far apart. 

The Brassica family is a popular enemy of your tomato crop. These include broccoli, Brussel sprouts, and cabbage. 

Corn is another harmful companion since it attracts tomato fruit worm, corn worm, and other pests.

Dills are harmless during the initial stages of plant development, sometimes even beneficial since they ward off hornworms. However, as they grow, they hinder the growth of tomato plants. It’s best to plant them at least a little distance away from your tomatoes.

Make sure your tomato crop isn’t planted close to any walnut tree. The tree produces a chemical called juglone, which hampers the growth of tomato plants. 

Fennel, eggplant, and potatoes shouldn’t be planted close either. 

Conclusion

Now that you know which plants partner well with tomatoes and which don’t, you can plan smart companion planting this season. Grow friendly crops together to enhance the yield and make most out of the piece of land you have.
