Companion planting

This is a method of planting where two or more different species of plants grown together will benefit each other’s productivity.

Companion planting is essential for any successful organic garden.

One  example of companion planting in the vegetable garden is to grow maize and beans together. The maize will provide a frame for the beans to grow on and the beans will fix nitrogen in the soil – increasing the amount available for the maize.

Sacrificial planting is a form of companion planting that encourages pests to eat plants surrounding crops, for example, caterpillars will prefer to eat the nasturtiums  planted around lettuce crops rather than eating the lettuces. Likewise, snails will eat calendula before they eat the peas and beans.
