Adding Cover Plants to your Organic Garden’s RotationSome of the toughest work in your garden can be accomplished by enlisting the help of other plants. You may already familiar with the concept of cover plants as green manure – plants are grown and returned to the soil as fertilizer before they reach adulthood – but cover plants serve other vital functions in your organic garden as well.
- Pest control – Flowering crops can attract predatory insects, such as solitary wasps and lacewings, and protect your organic gardening efforts from aphids and other pests.
- Weed control – The shade provided by leafy cover plants can prevent the growth of nuisance plants so that they are not able to take root before you begin growing your next primary crop.
- Water control – Cover crops slow down soil erosion by creating a breaker between rainfall and the surface of the soil. They also slow the rate at which water travels below the surface and can significantly increase soil moisture once they are tilled into the soil.
