Earthworm Castings

VermisTerra Earthworm Castings


Earthworm castings are the purest and the perfect form of soil enhancement for plants. They are completely natural, safe for the environment and easy to use. Earthworm castings contain crucial nutrients necessary for plants to grow healthy and vigorous. Castings also provide various beneficial bacteria and microbes that can improve the structure of the soil and break down nutrients to be more accessible for plants to uptake.

Unlike other manure and synthetic fertilizers, nutrients are readily available for plants and at the same time is slowly released so it remains effective for a greater length of time. It does not burn plants so there is no worry about applying an extended amount or directly to the plant.

Improves Soil Structure and Fertility

Microbes in the teas have the ability to create pore spaces in the soil. More oxygen are able to penetrate into the soil for even more biological activities to occur. As well as plant roots can root into the soil more easily. Well structured soil also soaks up water like sponge to retain water for longer periods.

Rich in Beneficial Bacteria and Microbes

High concentrations of exceedingly active mixture of bacteria and micro-organisms are within earthworm castings as they are added by the worm during the digestive process. The microscopic creatures assist in creating a healthy, living soil that will give plants the perfect atmosphere for optimum growth. Organic waste are deodorized during digestion as well, neutralizing odor and giving off a natural scent like a forest after the rain.

Regulates Plant Nutrients

Humic acid in earthworm castings have the capability to free up nutrients in the soil to make the nutrients immediately available for plants. Unlike earthworm castings, synthetic fertilizers and animal manure which must be broken down in the soil before the plants can absorb the nutrients.

Support Plant's Defenses

While plants remain healthy with the steady flow of time released nutrients, enzymes and trace minerals from earthworm castings.

Usage Guideline

Premium VS Standard

VermisTerra earthworm castings are aged 7-10 years which makes them pure, stable, and readily available for the plant to absorb. We do not include the compost or cut with any fillers. This is what makes our brand so effective: you get more pure earthworm castings. Our premium and standard grades of earthworm castings can be used interchangeably.

The Premium is more fine, ideal for indoor gardens, container plants, and seed starting. The Standard has small slivers of organic material in it, ideal for outdoor soil amendment, raised beds, trees and flowers.

How To Use Earthworm Castings

Make your own potting mix:
Mix 1 part earthworm castings with 3 parts media (combination of potting mix or coco coir) to make your own slow release container mix.

Top dress established plants:
Spread a handful around the base of established plants (1-2 inches thick), scratch into the surface of the soil, then water the plants. The microbes and earthworm castings need moisture to begin working. 

Add when transplanting:
Place 3 tablespoons to a handful of worm castings in the transplanting hole to protect and encourage root growth. 

Amend Soil:
To build organic matter in soil, place 10 LB of earthworm castings per 10 square feet of land to boost microorganisms and condition soil.

You can feed earthworm castings to your plants once a season. Microbes need warmth to multiply so you can skip winter if it’s colder than 40 degrees. For fruits and vegetables, you can use more earthworm castings: feeding them every other week. The pH of earthworm castings is 7 so you will never burn the plant.
