Introduction to Worm Casting Tea

Worm casting tea, also known as vermicompost tea, is a liquid fertilizer made from worm castings. Worm castings are the waste products of earthworms, which contain a high concentration of beneficial microorganisms, nutrients, and minerals. When brewed into a tea, worm castings release these nutrients into the water, creating a potent and natural fertilizer that can be used on all types of plants.

What are Worm Castings and Why are They Beneficial?

Worm castings are a type of organic fertilizer that's often used by gardeners to improve soil quality and plant growth. They're created by earthworms that consume organic matter, such as leaves and grass, and excrete it as nutrient-rich waste. Worm castings are a powerhouse of beneficial microorganisms, including bacteria and fungi, that help to break down organic matter and release nutrients into the soil.

In addition to these microorganisms, worm castings also contain essential nutrients and minerals that plants need to grow and thrive. These include nitrogen, phosphorus, potassium, calcium, magnesium, and zinc. Worm castings also improve soil structure, making it easier for plants to absorb water and nutrients.

How to Make Worm Castings Tea

Making worm casting tea is a simple process that can be done at home with just a few ingredients. Here's what you'll need:

  • 1 gallon of water
  • 1 pound of worm castings
  • 1 tablespoon of unsulfured molasses
  • Aeration device (such as an aquarium pump)

To make worm casting tea, follow these steps:

  1. Fill a large bucket or container with 1 gallon of water.
  2. Add 1 pound of worm castings to the water.
  3. Stir in 1 tablespoon of unsulfured molasses. This will feed the microorganisms in the worm castings and promote their growth.
  4. Attach the aeration device to the container and turn it on. This will oxygenate the water and help to release the nutrients from the worm castings.
  5. Let the mixture brew for 24-48 hours, stirring occasionally. The longer you let it brew, the more nutrients will be released into the water.
  6. Once the tea is ready, strain out the worm castings and transfer the liquid to a spray bottle or watering can.

Tips for Using Worm Castings Tea on Your Plants

Worm casting tea can be used in a variety of ways to nourish your plants and improve their growth. Here are some tips for using it effectively:

  • Use it as a foliar spray: Spray the tea directly onto the leaves of your plants to provide them with a quick dose of nutrients. This is especially effective for plants that are experiencing nutrient deficiencies or stress.
  • Water your plants with it: Use the tea to water your plants, either by pouring it directly onto the soil or using a watering can. This will help to improve soil quality and promote root growth.
  • Use it as a soil drench: For plants that are struggling to grow or are in need of a nutrient boost, use the tea as a soil drench. Simply pour the tea directly onto the soil around the plant's roots.

Common Mistakes to Avoid When Making Worm Castings Tea

While making worm casting tea is a simple process, there are a few common mistakes that can be made. Here are some things to avoid:

  • Using chlorinated water: Chlorine can kill the beneficial microorganisms in the worm castings, so be sure to use non-chlorinated water.
  • Letting the tea brew for too long: While it's important to let the tea brew for at least 24 hours, letting it brew for too long can cause the tea to become anaerobic and produce harmful bacteria.
  • Using too much tea: Worm casting tea is a concentrated fertilizer, so be sure to dilute it before using it on your plants. Using too much can burn your plants and damage their roots.


In conclusion, worm casting tea is a natural and effective way to nourish your plants and improve their growth. By following these simple steps, you can make your own worm casting tea at home and use it to promote healthy soil and plant growth. Whether you're an experienced gardener or just starting out, worm casting tea is a great addition to any garden.
