Compost Tea Recipes

Recommendations for Brewing Compost Tea:

~ Use a 400 micron compost tea brewing bag to contain the bulk of the compost.  400 Micron mesh will keep your brewer and your teas a bit cleaner than just throwing compost into a bucket.  More importantly our 400 micron compost tea brewing bags will allow the full diversity of biology to pass from the compost into your compost tea.

~ To prevent foaming, add ¼ - ½ tsp. of organic sunflower/ vegetable/ or neem oil per 5-gallons of water. (2 - 3 drops per gallon of water)

~ Dilute soluble ingredients first: Soluble kelp powder, Humic acid, and Liquid Fish Fertilizer,should be diluted in the water first. This will help to neutralize any acidic conditions from preservatives in soluble substances.

~ Diversity of compost is the key to compost tea: We highly recommend using a variety of composts for brewing compost tea. Especially homemade or locally sourced composts, produced from a variety of organic materials.  Small amounts of exceptional native soil / humus can be added to your home brewed compost teas. This will provide potential indigenous soil microbes.

~ Compost should smell sweet, earthy, or like mushrooms.  If it smells bad, it is bad! Do not use bad compost for making compost tea.

~ We recommend avoiding molasses or sugars in compost tea.  Bacteria are easy to culture in compost tea and are present in most compost, especially worm castings. Some plants do benefit from a more bacteria dominated soil environment such as plants in the Brassica family. If using molasses or simple sugars we recommend adding it near the end of the brewing cycle. Use 1 tsp of molasses per gallon of compost tea or 1 tbsp of molasses per 5-gallons of compost tea.

~ Keep compost tea under active aeration until you are ready to apply and serve fresh!

Compost Extract Recipes: Stir or aerate for 1 to 5 min



Compost Tea Recipes: Aerate for 12 - 36 hrs


Fungal Dominated Compost Tea Recipe: Aerate for 12 - 36 hrs


Compost treatment for brewing fungal compost tea: Fungi take more time to culture in compost tea.  You can enhance the fungal biomass in your compost teas with this compost treatment.

  • Place 2 – 4 cups of compost in a plastic container (for best results gather from different sources)
  • Apply ¼ cup of organic oat or soy flour or finely ground oatmeal across the compost and turn-under
  • Mix the recommended amount of soluble ingredients in the compost tea recipe with ¼ cup of water.  This may include; Soluble kelp powder, Humic acid, and/or Liquid Fish Fertilizer
  • Stir this mixture and evenly apply it to the surface of the compost
  • Cover with a loose fitting lid or moist cardboard and store in a cool dark place for 3 – 7 days


Activation times can vary based upon the presence of active fungi, dormant spores, moisture and temperature. Under the right conditions you should see a white fuzz of the fungi begin to cover the surface of the compost within 3 – 7 days.  This is an indicator of active fungi and will tell you that your compost is now ready for brewing into a fungal dominated compost tea.
