Companion Planting

Companion planting is the practice of planting symbiotic plants (those that benefit each other) together to foster symbiotic relationships between the plants. Companion plants can help spur each other's growth, deter pest, attract beneficial insects and organisms, and increase yields. A very common example is the three sister guild: corn, beans, and pumpkin. The corn plants act as climbing aid for the beans, the beans provide the soil with nitrogen, while the pumpkin acts as a living ground-cover keeping weeds under control and maintaining soil moisture. You can use the below companion planting list to find out which plants go well together and which don't.
