COMPOSTING 101

WHAT DO PLANTS NEED?

Fertilizer Compost

WHAT IS COMPOST? Compost is a rich, soil-like mixture that is

produced when organic matter breaks down. When compost is added to soil, it adds

nutrients that plants need and improves soil texture.

Composting is a way to make a usable product out of things we might just throw in the trash!
