Polyculture is a system of growing a diverse crop of plants that are interrelated and interdependent to one another. This system mimics the complexity of plants found in any natural ecosystem and these symbiotic relationships bring about more stability to the garden or farm.

With the variety of plants, the garden or farm can produce fruits and vegetables almost continually because they are maturing at different times. The thickness of the planting helps to eliminate weeds, and also works to keep the soil moist and cool.
