Composting is a natural process which occurs to almost all organics left outdoors long enough, the key to successful composting is to make the process work for you. With some simple considerations including balancing moisture, materials, and aeration, you can have rich, fertile soil to spread in your garden and flower beds each spring and fall for free! Compost can help retain moisture in dry areas of your yard, makes for excellent lawn fertilizer, and refreshes exhausted flow beds.
