The thriving organic vegetable garden

Category: Practical guidelines
Chapter: Gardening

Plants secrete substances via their roots and leaves that can have an influence on neighbouring plant growth. Some associations are conducive while others are not.

To successfully grow an organic vegetable garden, crop rotation is very important, in other words, avoid sowing the same plant in the same spot every year. This rotation prevents certain parasites or diseases from settling in. But it is also important to know how to correctly associate species so that they protect each other.

Plant association is one of the fundamentals of organic gardening.
