It's All About Mulching
Improving your soil is the most important thing you can do to successfully grow plants. One of the best ways to improve your soil is to regularly apply a layer of mulch to your garden.
Mulch benefits your plants by inhibiting weed growth, inviting helpful earthworms to move in, regulating the temperature of the soil, retaining moisture and providing a wide range of soil nutrients as the mulch gradually composts.
Any plant material can used for this purpose. If, however, you want to give your garden a real boost, try applying a layer of Lucerne Mulch. Lucerne is an excellent mulching material as it contains a wide range of minerals that your soil will love.
