Compost Tea/Extracts

Compost tea/extracts contain a diversity and abundance of soil microbes. These easily-applied liquids can "rewild" any soil, re-introducing the complete suite of soil microbes that will restore soil structure, nutrient cycling, and result in better plants.


Our compost tea and extracts are made at our homestead in Uxbridge, need to be pre-ordered, and can be picked up on-site. Our products are quality-controlled using a microscope and are made with only locally sourced, all natural ingredients.

High Quality Compost

Colleen's Composts: 

1. Fungal compost: home-grown, hand turned, thermal aerobic compost that are made specifically for compost teas and extracts. Our goals are safety, biodiversity, and high fungal numbers. This compost is intensively quality-controlled and microbial reports are periodically available. F:B is close to or greater than 1. Best suited for use on perennials, shubs and trees. Ideal for compost teas/extracts.

Limited quantities available, sold by the Litre.

2. Bulk compost: farm-grown, machine turned, thermal aerobic compost. This compost is made with 40% woody material, 40% horse manure with bedding (softwood shavings), and 20% spent grains. Will contain less weed seeds than other manure composts.

Sold by the yard or half yard. Delivery available up to 3 yards.


For both composts: Made according to Dr. Elaine Ingham's standards for BioCompleteTM Compost. Minimal to no weeds or pathogens. Records, microbial and nutrient reports available upon request.


Compost Tea Brew Kits

We manufacture 5 gallon compost tea brew kits using the Soil Foodweb-tested airlift brewer design by Tim Wilson. Our recipes are customized to your plants needs, and are microscope-tested. Kits include all you need to get started and keep going!

Compost Tea

Compost Tea is a liquid soil biostimulant. It is made using high quality compost as an inoculum of microbes. Water and microbial foods are added and the solution is vigorously aerated for ~24 hours. The microbial population booms to numbers exponentially greater than the parent compost. The resulting solution is sticky and best for foliar applications.

Compost Extract

Similarly to Compost Tea, Compost Extract is a liquid biostimulant that is brewed using high quality compost and water. The difference is that no microbial foods are added, so the microbes aren't reproducing as much. The resulting solution is more diverse, less sticky, andd better for soil drenches and deep root applications.
