What is Companion Planting?

Companion planting is a gardening wisdom that has says that when certain plants are grown together, you can get increased yields, better flavor, less disease and fewer pests.

It’s also a way of planting your garden that pairs plants together for a mutual benefit such as space, shade, pest control or nutrients.

For example, let’s say you are talking about tomatoes. Maybe you have trouble with aphids or spider mites on your plants each year. This is your host plant.

You would choose a companion plant (or 2) that helps deter these pests away from your tomatoes. You can also choose a companion plant that helps improve the flavor of your tomatoes too.

What are the Benefits of Companion Planting?

Companion planting isn’t just about pest control, it has lots of other benefits as well. Here are just a few of the benefits of using companion planting in your garden:

Changes in the Soil: Different plants can either add or take away elements of the soil. Legumes are nitrogen fixing and help make nitrogen more readily available for heavy feeders.

Root vegetables can help break up the soil and plants with longer roots can draw more nutrients up for crops with shallow roots.


Help Control Insects: Companion planting can help control pests in your garden by repelling them or as a trap crop to collect pests.


Provide Ground Cover: Low growing plants help provide a living mulch and suppress weeds around the host plant. They can also prevent erosion.


Save Space and Time: When you plant crops that don’t compete for nutrients you can place them closer together without overworking the soil.

This also works with similar crops, like peppers and tomatoes, which have the same sun, soil nutrient, and care requirements. Planting them together will allow you to prepare the beds and care for them efficiently.

Fennel: Fennel will inhibit the growth of your basil plants. Fennel stunt the growth of many plants, so it’s not a great companion in general and should be kept in its own spot in the garden.

Cucumber: Don’t plant aromatic herbs like basil around your cucumber plants or the flavor of your cucumbers might be affected. Since cucumbers contain a lot of water they can sometimes take on the taste of the plants planted close by.

Sage: While sage and basil won’t hurt each other, they have very different growing requirements. Sage prefers dry, sandy soil, while basil needs a lot more moisture and nutrients.

Rue: Rue can inhibit the growth of basil and should not be planted along side basil.
