Composting helps reduce the amount of yard waste in landfills. It also returns valuable nutrients to your soil. You can start a compost bin by layering organic materials.
Layer 1: Add 3 to 4 inches of organic matter, such as leaves or dried grass.
Layer 2: Add 3 to 4 inches of green materials, such as kitchen vegetable scraps, fresh grass clippings, or green plant materials.
Do not add pet waste, meat scraps or fat, diseased plants or noxious weeds to your compost bin.

Thatch is a layer of undecomposed organic matter that can build up and create thick layer that restricts water and air movement. Grass clippings do not cause thatch when you properly maintain your lawn. Mow at the right height and before grass gets too tall. This helps grass clippings break down quickly and return nutrients to the soil. Thatch usually forms when lawns are overfertilized or overwatered because the grass grows faster than it can decompose.
