Compost is a very important part of your garden. In order to create the compost you need five very important ingredients: air, water, heat, nitrogen and carbon. You can introduce air circulation by crossing branches. Water your pile so it does not dry out, but you do not want to water it too much so that it gets mushy. your compost pile has to be warm in order for it to compost. You can get nitrogen by using green things from your garden like weeds and grass, and you can get carbon by using hay or anything that is brown.
