A Step-by-Step Guide to Vermicomposting

Vermicomposting is a process of composting green waste such as kitchen scraps, plant and animal waste, food processing waste, etc. using earthworms. Hence, it is also known as worm composting.

Process of Vermicomposting

Earthworms feed on organic waste that equals to their body weight. They excrete 50% of the food consumed by them. This excreta of earthworms is known as vermicompost.  During the process of vermicomposting, earthworms are added to organic waste, which they eat and pass through their digestive tract. The digestive tract of earthworms secretes chemicals to break down the soil and organic waste, which are then excreted in the form of cocoons or castings. These castings are then added to the soil to increase its nutritional content and improve its structure.

How to Use Vermicompost

Vermicompost can be used in multiple ways. You can add it to potted plants or to the soil in your garden or farm. Here is a detailed explanation of how to use vermicompost for different scenarios.

Tips to Use Vermicompost for Potted Plants

  • Mix vermicompost in a 1: 4 ratio to the potting soil.  Add it to your pots and plant a seed or sapling. Add vermicompost to the pot at regular intervals.
  • You can also make a  compost tea with vermicompost castings and water. Spray this tea near the roots of the potted plants.

Tips to Use Vermicompost in Garden or Farm
