Companion Planting Chart

Companion planting is one of the best methods of defense against crop diseases that an organic gardener can use. The idea behind companion planting is to encourage symbiotic relationships among the plants and animals in the garden, so that pests are kept in check and the eco-system regulates itself without need for pesticides or chemical fertilizers. Some plants can be used to attract beneficial insects, others can be planted for their pest-repelling properties. Still others can help bring nutrients up through the soil so that other plants can benefit from them. Here is a chart I made that details which plants can be used with others for companion planting. Feel free to copy, paste, print and hand out to random strangers. :)

Most of the information i used to create the chart was obtained from http://www.ghorganics.com/page2.html, and some also came from
