Companion Plants and the Tomato Garden

Companion Plants help other plants in a number of ways. Choosing the right companions can help enhance the condition of the soil, provide cover for root systems, attract beneficial insects, repel harmful insects, assist in growth and improving vegetable flavor. Planting companions has been used in gardening for hundreds of years and are an integral part of knowing how to grow tomatoes.

The North American Indians devised the infamous "Three Sisters" method of companion gardening. The Three Sisters are Corn, Beans and Squash. This method of companion farming was not isolated to one tribe or region. This method was used throughout North America. A mound was formed and a few corn seeds were planted in the center. Once the corn sprouted, beans were planted around the corn on top of the mound. The squash was then planted around the sides and base of the mound. The corn stalks provided support for the bean stalks and the squash provided a protective cover from intruding weeds, pests and helped retain moisture during hot summer weather. It was a simple and effective example of companion planting. While the Three Sisters have a symbiotic relationship, corn and beans are companions to be avoided in the tomato garden.

Vegetable plants aren't the only type of companion plants, many herb plants and flowers are very good companion plants. Multible plants that are companions of a particular vegetable, may not be compatible with each other. It can get pretty confusing. There are many charts and lists attempting to demonstrate the companion plant possibilities, but cross referencing those possibilities can be daunting. The goal here is to simplfy the use of companion plants for growing healthy, tasty fresh tomatoes.

Companions can serve one or more purposes in helping tomatoes, a few may be helped by tomatoes in the process. The following vegetable plants, herb plants and flowers are the core group of companions for tomatoes. There are plants to be avoided in the tomato garden. The listed plants to be avoided may be grown elsewhere, preferably in the another plot away from tomatoes. Plants such as Sunflowers are often planted far away from the main garden and are used as trap plants. Trap gardens are used to draw the most threatening insects away from the main garden. Sunflowers are often used as a trap plant because of the beauty and of course the seeds. Here's a guide for tomato garden companions.
