Companion Planting

Companion Planting

Companion planting makes use of specific plants as insect repellant and growth stimulators. The chemical make-up of some plants simply is unattractive to various insects and attractive to certain plant growth.

Planting beans near or among potatoes will limit the amount of Colorado potato beetles present. The potatoes, in turn, discourage Mexican bean beetles. Chives planted among lettuce and peas limit aphids. Radishes contain and often stop striped cucumber beetles. Geraniums deter Japanese beetles. Other flowers, such as marigolds, chrysanthemums, cosmos, and nasturtiums, add color while acting as a general insect repellent in your garden.

The following table will help you plan your companion garden to aid in deterring the harmful insects as well as providing natural growth stimulators for your plants.
