Companion Planting

In life there are just some things that go well together. Plants are no exception! Some plants may help each other by improving the soil with minerals and nutrients. They can also attract birds and other natural predators that will deal with harmful insects. Finally, some plants will enhance the growth rate and flavor of others when planted next to each other.

Companion plants can be used as a border or a backdrop to your garden. You can even interplant them among your flower or vegetable beds.

The following list is a guide to help you bring a more natural and balanced ecosystem to your landscape.

“Companions” are plants that are mutually beneficial to each other when planted together. “Allies” are plants that provide each other protection from harmful pests and/or improve the growth of other plants. Finally, “Enemies” are plants that can cause detrimental effects when planted near each other.
