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.

Compost Tea and a New Organic Compost!

May 28, 2024

Our compost tea will be ready this week, hopefully by Friday. Our tea has always been good, but this year we are working on making it even better. Please let us know if you can see good results from using it, and if it seems to be more effective.

Say Hello to ECOPLUS Organic Compost! We are replacing our A-1 Eco-Grow compost with the newly-available ECOPLUS Organic Compost, an OMRI certified organic compost made by A-1 Organics in Colorado.[Read More]
