Tomatoes and Companion Planting

GardenZeus expert Darren Butler has found tomatoes generally to be unfussy companions for many other garden vegetables. Most varieties don’t need insects for pollination, so planting fragrant herbs and flowers to attract pollinators is less important for tomatoes than for other garden vegetables, such as cucurbits.

It is important to consider where tomatoes will be placed in your garden more based on size and habit of the tomato variety, to ensure that individual tomato plants receive plenty of sunlight, and both for beneficial shading of other plants during hot summers in your zone and to avoid shading other plants that need full sun. In small gardens, indeterminate tomatoes are often planted in the back (in the farthest areas from the direction of sunlight) and trained upward for efficient use of space.

Avoid planting tomatoes with or near other Solanums, such as potatoes and eggplants; with other members of the nightshade family, such as peppers; or in soil where tomatoes or relatives have been grown during the past 2 to 3 years.

Traditional companion plants for tomatoes include basil, borage, carrots, chives, marigolds, nasturtiums, and onions.
