Brew Your Own Compost Tea

What is compost tea?

Compost tea is water that compost has been steeped in. As a result of soaking, the water becomes infused with the compost’s nutrients and microorganisms. Microorganisms includes healthy things for your soil like bacteria, fungi, protozoa, nematodes, and micro arthropods.

What are the benefits of using compost tea in growing plants?

Compost tea is like food for plants. By adding microorganisms to your soil you create a healthy ecosystem in your soil, and healthy soil equals healthy plants. Finally, by improving plant and soil health your plants naturally become more pest and disease resistant. Other benefits of use are:

  • Improved water retention capacity of soil; which reduces the need for frequent watering

  • Improved soil structure; the biological components in a soil are what create its structure. For good soil structure, all organism groups in the food web — bacteria, fungi, protozoa, nematodes and micro arthropods — need to be present. By using tea you are adding these microbes

  • Stimulated plant root growth; deeper roots retain moisture better and help reduce runoff
