p90965 Ingredients 7ee8c9d73a 516643242

To make worm tea, you will need the following ingredients:

  • Worm castings: These are the waste products produced by worms during the vermicomposting process. They are rich in nutrients and beneficial microorganisms.
  • Water: Using clean, non-chlorinated water is important to ensure that the microorganisms in the worm castings are not harmed.


Making worm tea is a simple process that involves the following steps:

  1. Gather the necessary equipment: You will need a container to hold the water and worm castings, an airstone or air pump for aeration, and a stirring utensil.
  2. Measure the ingredients: For every gallon of water, you will need around 1 cup of worm castings. Adjust the amounts based on your desired batch size.
  3. Add water to the container: Fill the container with water, leaving enough space for the worm castings.
  4. Add the worm castings: Place the measured amount of worm castings into a mesh bag or directly into the water, making sure they are fully submerged.
  5. Mix well: Use a stirring utensil to agitate the mixture and ensure that all the nutrients from the worm castings are released into the water.
  6. Aerate the tea: Attach an airstone or air pump to provide constant oxygenation to the mixture. This helps promote beneficial microbial growth.
  7. Let it steep: Allow the mixture to steep for 24-48 hours, ensuring that it remains aerated during this time.
  8. Strain and store: After steeping, remove any solid particles by straining the liquid through a cloth or mesh sieve. Pour any leftover tea into containers for storage.

Worm tea can be used to nourish your plants and promote their growth. Here are some ways to use worm tea effectively:

  • Dilute the worm tea: Mix the worm tea with water in a 1:10 ratio, meaning one part worm tea to ten parts water. This helps ensure that the nutrients are evenly distributed and not too concentrated.
  • Apply as a foliar spray: Use a spray bottle to mist the diluted worm tea onto the leaves of your plants. This allows the nutrients to be absorbed directly through the leaves, promoting healthy growth.
  • Water the soil: Pour the diluted worm tea directly onto the soil around your plants. This helps enrich the soil with beneficial microorganisms and nutrients, improving its overall health.
  • Use during transplanting: When planting new seedlings or moving plants to larger pots, water them with diluted worm tea. This helps reduce transplant shock and provides an extra boost of nutrients for their root development.

This is because these bacteria need oxygen to do their job effectively.

Aerating worm tea is easy. All you need to do is use an air pump or stir the mixture vigorously every few hours for 24-48 hours while it’s steeping. This will ensure that enough oxygen gets into the tea and enhances microbiological activity.

Aerated worm tea has been found to be more effective in improving soil health and promoting plant growth compared to non-aerated versions. So if you want to make the most out of your worm tea, don’t forget to give it a good dose of oxygen!
