Marigolds can help repel a number of common eggplant pests, including nematodes. When in bloom, marigolds will also attract beneficial insects such as lacewings to your garden, which prey on aphids.

Colorado potato beetles are a major pest of eggplants, as well as other members of the nightshade family. Bush beans can actually keep this pest away, so pairing bush beans with your eggplants can help protect your plants. Because bush beans stay smaller than vining bean varieties, they are also less likely to overwhelm your eggplants.

Nasturtium is another fantastic pollinator plant that can help boost your eggplant yields. But nasturtium is also a top “trap crop,” which can be used to protect your eggplants by luring pests away. Nasturtium come in both mounding and trailing varieties, but mounding types tend to be easier to keep in garden beds as they grow more compactly.

Spinach Spinacia oleracea

Spinach is a low-growing plant that matures quickly. Sowing spinach seeds beneath your eggplant is a smart use of gardening space as you may be able to gather a harvest or two of spinach before your eggplants mature. What’s more, by keeping spinach leaves sheltered beneath taller eggplants, you can slow down spinach’s tendency to bolt and extend your harvest.

Like many other flowering herbs, oregano is useful for both attracting beneficial insects and repelling nuisance pests. Bees absolutely adore oregano flowers and sowing this herb near your eggplants can increase your vegetable harvest. In the kitchen, the flavors of oregano and eggplant pair beautifully together in such classic dishes as eggplant parmesan.

Mojito spearmint

Denny Schrock

Mint plants can repel flea beetles, aphids, and other pests and their flowers are very attractive to pollinators. Growing mint near your eggplants can help keep your garden beds pest-free naturally. Just keep in mind that mint can spread quite aggressively, so you may want to keep this plant in containers or pots placed among your eggplants.

Hot Peppers

It's usually best to avoid growing plants in the same family close together because they can be susceptible to the same diseases. Because hot peppers and eggplants are both members of the nightshade family, planting these veggies together may not be an obvious choice at first. However, hot peppers’ spice level makes them naturally resistant to most pests and they have the same growing requirements as eggplants, meaning you won’t have to do a lot of extra garden prep to keep these plants together.

wormwood plant

Wormwood is another plant that is often overlooked in the garden, although it is sometimes kept as a pollinator plant. When paired with eggplants, wormwood can keep pesky flea beetles away. A member of the Artemisia family, wormwood is known for its highly fragranced leaves, which are often used in homemade potpourri making.
