Lettuce makes a nice ground cover that acts as a live mulch to hold moisture in the soil and keep the garden soil cool.

Lettuce also helps prevent the spread of disease and damage caused to tomato leaves by water splashing up from the soil.

In return, lettuce and other leafy green vegetables, such as spinach and arugula, can benefit from the shades of the taller tomato plants.

The tomato also keeps the lettuce safe from worms that chew on its leaves.

Also, lettuces from the Asteraceae family should not be assumed to have the same benefits as cabbages from the Brassica family. These two possess different effects when planted with tomato plants.

Bad Companion Plants For Tomatoes

If you disregard the amazing benefits of companion planting, at least know which vegetables, crops, or plants can wreak havoc and potentially harm your tomato plants instead of protecting them.

This group of bad companion plants includes cabbage or anything from the cabbage family, corn, dill, fennel, eggplants, and walnuts.

Cabbage may seem to belong to the same family as leaf lettuce, which works as a good companion plant for tomatoes.

However, cabbages do the exact opposite. Cabbage goes under a different family of cruciferous vegetables, Brassica family.

On the other hand, leaf lettuce falls under the category of leafy greens with arugula and spinach.

Under the same cabbage family, these members are not suitable for tomatoes:

BroccoliBrussel sproutsKaleCauliflowerRutabagaTurnipKohlrabi

Companion planting cabbage with tomatoes and these vegetables won’t do any good. However, there exist some plants that love cabbages, such as:

BeetsCeleryOnionsBush beansMarigoldNasturtiumA few strong herbs

If you have already planted cabbage and tomatoes together in your garden, avoid the latter from severely shading the cabbages.

They should stay a few feet away to avoid the tomato roots from reaching the cabbage. Apart from this, cabbages get the most benefits from tomatoes.

The tomato plant can drive away moth larvae and caterpillars that feed on the leaves of cabbages.

Corn planted with tomatoes spells a huge disaster. Corn worms are no different from what gardeners call the tomato hornworm when it comes to pests.

Corn attracts more of these tomato hornworms, putting the two plants together in one setting will kill them two times faster.

Although the young dills may help protect the tomato plant from tomato hornworms, planting a mature dill nearby inhibits the growth of the tomato.

Make sure to keep a good distance between the seed of dills and tomatoes in your garden when planting.

Eggplants and potatoes do not work well with the tomato plant if these plants sit very close to each other.

Early and late blight will accumulate in the garden soil, making it unhealthy soil for different plants in the years to come.

Apart from the dill plant, fennel also stunts the growth of the tomato plant. On the other hand, walnuts promote the same effect with its allelopathic element experts call juglone.

This chemical causes walnut wilt, a disease making tomatoes sick, causing them to wilt and die.

Other plants containing juglone include:

English walnutPersian walnutBlack walnutHickoryPecanButternut
