Good Neighbor crops are those that can be planted and harvested between the planting, growing, and harvesting time of the tomatoes. They are also good neighbors because they have neighborly qualities by helping each other grow and repel insect pests and diseases. Although the plants my have beneficial qualities, they are still simply plants. Don’t expect a miracle just because you planted two things side by side.

Nasturtiums deter whitefly and aphids, other insect pests. Just as in cooking, basil helps increase the flavor and vigor of the tomato plants. Marigolds help with their pungent odor, which deters most insect pests, especially the nematode.

Tomato Gardening with Companion Leafy Greens

Finally, spinach, lettuce and arugula are good neighbor crops because they stay small in between the tomatoes. As the tomatoes grow and the weather gets hotter, they provide shade for their small, shade loving companions.

Avoid Certain Companion Plants with Tomato Gardening

In addition to the good neighbors of tomato gardening, there are also bad neighbor crops that you need to avoid from planting with your tomatoes. These plants are detrimental either to the health of your tomatoes, or for their own sake.

Tomatoes suffer from a common pest, the tomato fruit worm. Corn has a nearly identical pest, the corn ear worm. Growing both corn and tomatoes together increases the probability that you will attract either, or both, of the pests. All members of the cabbage family, including broccoli, cauliflower, cabbage, brussels sprouts, kale, rutabaga, and kohlrabi, all stunt the growth of tomatoes. Fennel does the same. Potatoes, eggplant, and red peppers, which are all in the same family as the tomato, are also detrimental to each other. The tomato makes the potato more susceptible to potato blight, as well as the eggplant and red pepper to blight.

Tomatoes have many companion plants, and planting them together can save you time, energy, and money in the garden. On the other hand, be careful to avoid the bad neighbor plants, which can have a detrimental effect on your vegetable garden. Get creative with your gardening and discover new ways of planting these companions together in order to have a happier garden and better yield.
