Organic control options take on a new level when using companion planting. The use of such plants brings together almost all aspects of what is right about organic gardening. For a start using seeds means that chemical use in the garden can be reduced. Companion planting almost means that you are increasing the range of plants and biodiversity in your garden
Of course with organic gardening there is a certain level of failure and of plant damage. But this is a natural part of nature and all pest damage cannot be avoided and should not be avoided. But with careful and clever planting in your garden you can significantly reduce pest attacks, reduce weed growth and provide better soil conditions for growth
In the vegetable garden you can mix all sorts of vegetables together to create a mix of leaf types and vegetables together. The result is a confusing mass of vegetation which leaves slugs and snails at odd about which plants to eat and which plants to avoid. This is one way to control slugs in your garden
