Worm tea is ultimately the end result of steeping worm castings or vermicompost in water. Worm tea is known mostly for its ability to boost microbiological activity in soil by adding bacteria, fungi, actinomycetes, and protozoa to the soil. If you are already worm farming and have easy access to worm castings then making worm tea will be a breeze, or if you want to start a worm farm to reap the benefits of the castings we have you covered with our many options of worm kits.
Things you will need to make worm tea:
- Porous bag (Uncle Jim’s worm bag, old t-shirt, panty hose, cheese clothe, etc)
- dechlorinated water such as: rainwater, pond, or distilled water
- bucket ( 5 gallon will work)
- Worm Castings
First thing you will want to do is add your worm castings to the porous bag of your choosing and tie the end of the bag. Place the bag of castings in your container of water and let it steep overnight. In the morning the water should be light brown and that water is your worm tea! After the bag of castings is ‘spent’, you can add it to a potted plant or to your garden because it has finished its tea making job. Ultimately, to make a batch of basic compost tea with worm castings, all you really need to do is soak some vermicompost overnight in water.
Now that you have your worm tea brewed let’s talk about how to use it. If you have a large garden or many houseplants, worm compost tea can be diluted with water to cover more area. You simply take 50% water to 50% worm tea. I suggest putting your worm tea in a watering can, however, a sprayer or spray bottle works well too. Just be sure to strain the worm tea before adding it to a spray bottle. Now simply water your house plants, outdoor potted or hanging plants, and you garden. Cover a whole plant with worm compost tea including the leaves. Many people believe that the beneficial microbes in worm tea help protect plants from diseases.
And that is it! Now you know how easy it is to make worm tea. It is just one of many great benefits to having your own little worm farm. Your plants will especially thank you!
Note: You can get higher-quality worm tea by adding a sugary liquid and an aquarium bubbler — see instructions.
