Garden Compost Facts


Compost is the rich, crumbly result of the decomposition of organic matter. It improves all types of soils and benefits flowers, vegetables, trees and shrubs. A home compost pile reduces the strain on overburdened landfills.

In heavy clay soil, compost loosens soil so that roots can spread more easily and air and water can reach the roots.


Compost increases the water retentiveness of sandy soil, helping plants to take up more water and nutrients.


"Good" bacteria, worms and insects thrive in compost-improved soil. These organisms help to aerate soil, break down organic components and suppress plant diseases.


Compost neutralizes soil, raising the pH of acid soils and lowering the pH of alkaline soil. These soil conditions help plants take in more nutrients.


Much of the waste brought to landfills is kitchen and yard waste, including grass clippings, leaves and kitchen scraps--all of which could be composted.
