See Companion Planting for Insect Contro

What is companion planting?
Some plants do better when in the company of other plants. Companion planting is using this knowledge to increase plant performance both as insect control and to take advantage of the symbiotic relationships between plants.

How can I companion plant?
Companion planting requires some experimentation. What may be successful in one garden may not be successful in another garden. This may be caused by different microclimates, soil types, plant varieties and cropping practices.


SYMBIOTIC COMPANION PLANTING CHART

FOR GARDEN VEGETABLES
Symbiotic plant companionship is when one plant aids another plant's growth either by making nutrients more available underground (legumes set nitrogen) or by providing a micro-climate above ground (tall, sun-loving plants provide shade for lower growing cool-loving plants.)
