By growing eggplant alongside other plants, you can help boost the growth of your eggplants or the other crops, repel insects, or heighten flavor.

Luckily, below you will find a handy guide that will find a companion plant for your eggplant and take the guesswork out of your eggplant gardening.

What Is Companion Planting?

Companion planting is strategically planting a crop with another crop to gain some advantage in production, flavor, or protection from pests.

Benefits of Companion Planting

Companion planting allows you to grow more plants and support the ones you have, since the two or more plants establish a beneficial relationship that aids one or both companions.

It can also replace the need to purchase other plant care supplies, two of the items most commonly purchased for gardening. However, you will have to buy less of these if you buy the right plants and plan your garden so that the plants you were already going to be planting are arranged in a way that they help the crops next to them.
