Finished Compost

You may be new at composting and wonder how to tell when compost is finished decomposing.

A batch of compost is finished and decomposed when:

The raw materials is no longer recognizable as the raw materials you put in: grasses, twigs, coffee grounds, banana peels, weeds and such. Although, some small pieces may still be recognizable.

Finished compost looks similar to peat moss, or potting soil.

The material is rich and crumbly.

The compost is no longer warm to the touch. It is no mare than 10 degrees F warmer than the outdoor temperature.

Where did it go? Finished compost shrinks to about 1/3 of the original volume. It is denser, more compact, and has less moisture content than the original materials.

Note: It is okay to use compost a little before it is completely finished, as long as it is no longer hot.
