Mulch saves water and improves the soil.

Using mulch to cover the soil  around plants will help to conserve moisture and also reduce weed growth. Organic mulches break down and are incorporated in the soil adding organic matter and nutrients to the soil, regular mulching and fertilising your soil will help to maintain your soil health which will improve your plant health. In winter if you are using frost protection cloth remove the mulch beneath the cloth so the radiant heat from the earth can escape and warm the air inside the protective cloth.
