Tomatoes and basil are said to improve each other's flavor, while companion flowers attract beneficial insects and repel harmful ones.

Questions people ask

What plants belong in a tomato guild?

A practical tomato guild starts with tomatoes, basil, marigolds, nasturtiums, chives, and shallow-rooted companions like carrots around the edges.

Is basil actually a good tomato companion plant?

Basil shares tomato growing conditions, fills gaps around the crop, attracts gardeners to harvest often, and is commonly used with tomato guilds even where flavor claims are anecdotal.
