Companion Planting
Companion Planting protects your plants against pests and diseases whilst also improving crop yields.
Companion Planting works because many plants attract or repel different insects. By companion planting you are allowing one crop to use the use the survival skills of another crop, and visa versa. Its green, is easy and it works.
