Back Yard Composting

Getting Started

Back yard composting requires a little bit of space, a bin, and a basic understanding of the composting process.
Compost provides a long-term source of many nutrients not typically found in Colorado’s soils. Compost also helps your soil hold water longer.

Using Your Compost

Compost is ready when it is dark brown, crumbly and when the ingredients are not recognizable. You can use compost in two stages:

Finished Compost

Use as a soil amendment in gardens (anytime)
Use as an ingredient for potting soil
Place around plants, trees, or on lawns as a mulch or top-dressing

Partially Finished Compost

(all particles are not completely broken down)

Place around plants, trees, or on lawns as a mulch or top-dressing
Spread compost in your garden in the fall so it will enrich the soil over the winter to help your spring planting
