How to Use Worm Castings

For Potting Soil

Mix worm castings in to your potting soil creates a living and potent potting mix. Mix upto 25% castings into your potting mix.


Our go to mix is 37.5% coco coir, 37.5% peat based potting mix (we use Berger Om6), 25% worm castings, and 1 tsp of Espoma Garden Tone per 1 cup of mix. You can also get great results with using just 75% of one potting medium and 25% castings.

For Transplanting

Transplanting is a perfect time to add worm castings to your beloved plants. Castings benefit plans of all sorts from leafy greens in small 2 inch pots, larger vegetables in 4 inch pots, to  shrubs, trees, and other perennials. Castings are simply added to the hole you dug for the transplant, and they will go to work in the soil for you.

Application rates:

2 inch pots: 1/2 cup

4 inch pots: 3/4 cup

Larger plants: dig a hole three times the size of the pot, fill 1/3 of the hole with castings, place plant on top of castings, and replace soil in the remaining space.

For Garden Bed Preparation

Gardens large to small can all benefit from a boost to microbial life in the soil. Castings should be applied at a rate of 1 qt per 8 sq. ft. This means our 2 gallon boxes will treat a whopping 64 sq. ft. 

To use, evenly spread the castings across the surface of the garden soil, then using a rake, harrow, cultivator, or other light tilthing implement, work the castings into the surface. Water in well.


Application of castings is best on an overcast day or in the evening as the microbes in castings can be harmed by direct sun light.

Our worm castings are made from organic inputs:

  • Nutrient Dense Microgreen waste

  • Mushroom Substrate

  • Coconut Coir

  • microbial diverse and rich Organic fertilizers.

  • May contain Predatory Mites, Nematodes, and/or Isopods


These worm castings are processed in a facility that

uses vermiculite and perlite, and trace amounts may

be present in the castings. While we do our best to remove the worms, beneficial invertebrates, and any viable seeds before packaging, they have been known to get through. They will not harm your plants.
