Compost Tea

What is compost tea?

Compost tea is a liquid soil amendment made from compost and beneficial microorganisms. It is commonly used by organic gardeners to introduce beneficial microbes into the root zone, supporting a healthy soil ecosystem and helping plants make better use of available nutrients.

Applied as a soil drench or, where appropriate, as a foliar spray according to product directions, compost tea can become an important part of a balanced plant care program.
