Compost Tea Featuring Local TerraForma Compost Ready this Weekend!

May 12, 2026

Brewing Compost Tea

You can think of compost tea as vitamins for plants; they are a great overall plant health booster. In turn, healthy plants are better able to resist pests and diseases. Our customers have told us that our compost tea has very clearly strengthened and improved the growth of their plants. Benefits associated with compost tea include:

Improves soil health. If soil is nutrient-rich, the need for fertilizer is minimized.

Improves water retention. This reduces the need for frequent watering.

Improves 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 compost tea you are adding this large
spectrum of beneficial microbes.

Stimulates plant root growth. Deeper roots retain moisture better and help reduce runoff.
