Pair basil and marigold for a powerful pest fighting duo. The two can grow well together and they both are great at helping to control pests in your garden.

Then alternate between the two adding in other great options like onions and garlic to help protect your garden beds. You can fully harvest your basil early to make more room for mature plants after using the basil to protect young tender ones.

What should you not grow with basil?

Cucumber growing on trellis.

Basil should not be planted near cucumbers. This is because cucumbers tend to take on the flavor of any pungent plants that are growing nearby.

If you plant basil near your cucumbers they may take on a less than pleasant taste that can render them nearly useless in your kitchen.

Basil, like most other plants, should not be grown near fennel. This is because fennel lets off a chemical into the soil that is toxic to most other plants.

If you grow this nearby your basil or any of your other plants you risk them dying. If you want to grow fennel, grow it in a pot where it will not be sharing the soil with other plants.

Sage and rue while both are great companion plants for roses in the flower beds are not good companions for basil. This is because these herbs can affect the taste and fragrance of each other, leaving you with a large batch of herbs that don’t quite taste right.

Stick to planting basil with things that will enhance the flavor in a good way.
