Companion Planting Guide

Some plants help each other grow. Others compete for nutrients or attract the same pests. Use this tool to find the best (and worst) neighbors for any vegetable.

What Is Companion Planting?

Companion planting is the practice of growing certain plants together for mutual benefit. Some combinations repel pests, improve pollination, or enhance flavor. Others compete for space, nutrients, or sunlight.

Classic Companion Planting Pairs

The Three Sisters: Corn, beans, and squash have been grown together for centuries. Corn provides a trellis for beans, beans fix nitrogen for corn, and squash leaves shade the soil to retain moisture.

Tomatoes + Basil: Basil repels aphids and whiteflies while some gardeners believe it improves tomato flavor.
