Worm tea is a fertilizer generated organically by soaking worm castings in water. By soaking the castings in water all night, you may create a worm tea that can help your plants grow faster. In addition, the tea works to prevent and treat plant diseases thanks to a load of powerful microbes.

The term worm casting refers to worm droppings. Red wiggler worms produce worm castings by decomposing food and other organic residues in the worm bin. Castings are dark in color and have a brittle texture. You may also find it has a strong soil smell. In contrast, the color of the tea itself is light brown. Furthermore, although ultimately you are working with droppings, you'll find the castings and the tea do not have a strong odor.

Benefits of Worm Castings Tea for Plants

Due to the worm's different physiological life stages, the finished worm castings boast a large and diversified bacterial population. As a result, the tea imparts many benefits when used in your garden.

  • Helps restore contaminated soil:If you add worm tea regularly to your garden, the microorganisms will process and convert organic and inorganic substances. Worm compost tea will help absorb the toxic substances present in chemicals.
  • Help repel pests:Watering plants with worm compost tea provides a nutrient-dense food rich in beneficial bacteria. Therefore, both plants and soil will be stronger in fighting pests and plant disease.
  • Protect house plants:You can make and use worm tea to inoculate the soil of your potted plants. It will help suppress the harmful pathogens that easily infect sterile pots. Beneficial microorganisms in worm tea can also supply nutrients to young plants and seed cuttings.
  • Improves soil structure:Tea microbes can open up pores in the soil. Thus, the presence of this pore space allows oxygen to reach the soil. As a result, plant roots can grow more quickly. Furthermore, due to a good soil structure, water absorption is also improved, and the ability to hold water in the ground is also longer. So a good tea recipe is beneficial for both soil and plant growth.
  • Encourage healthy foliage:Applying worm cast tea as a foliar spray can stimulate your plants to grow more leafage and broader stems. It is highly beneficial to plants that do not receive enough sunlight.

How to Use Worm Casting Tea on Your Plants

If you are making homemade worm casting tea, be sure to use it within two to three hours after the process of steeping worm castings is complete. Use worm tea when the soil absorbs moisture best, i.e., morning or evening. You can sprinkle worm tea directly on the ground, or you can fill it in a spray bottle and spray it on the plants. If you see signs of plant disease on the leaves, it is better to spray it directly. This is the best way to ensure the worm casting tea can improve your plant health.

You should dilute your worm compost tea. In a watering can, add three ounces of worm tea to one gallon of water. Use regularly once a week to feed and strengthen your plants. In addition, you should water your plants as usual.

If you don't have a watering can, a spray bottle works too. Strain the worm tea first before pouring it into the spray bottle. Spray both the soil and the leaves of your flowers and vegetable gardens generously. This allows the worm compost to combat harmful pathogenic microbes and improve plant health.

If you have a drip irrigation system for your plants, pour in the worm tea and water your plants once a week. This method is more appropriate for large-scale operations. The watering process will run automatically to cover all plants on a large area and increase the presence of beneficial microorganisms.

The best method for proper worm tea application depends on the area of the plant or garden, the type of plant, the purpose, and the equipment used. For example, two acres of agriculture will need 50 gallons of worm tea. If you make your own worm tea, ensure you use a good tea recipe.

How to Make Worm Tea

There are several methods to make worm tea. The first is through extraction. To get started, obviously, you will need worm compost. This can come from any composting worms in your worm bin. In addition, you will need a water bucket and a cheesecloth to act as the compost tea bag. This method results in a very basic compost tea. Use dechlorinated water and mix with two and a half cups of worm compost.

When using the extraction method, the main difference in how to brew your compost tea is whether or not you use a tea bag. Water is flowed through worm castings during the extraction process to withdraw beneficial microbes from the castings into the water. Next, place the worm manure in an existing filter, porous bag, or cheesecloth.

Alternatively, you can mix the worm castings into water. Allow it to be wholly immersed in water and stand for one to two hours. Then strain the solids from the water.

The second way to make worm tea is by aerobically brewing your tea. Our tea recipe calls for a five-gallon water bucket and five cups of worm castings. You'll want to mix the casting in five gallons of dechlorinated water and add one ounce of corn syrup or molasses. In this tea recipe, corn syrup or molasses provide valuable food sources for the microorganisms present in worm poop.

Next, place the worm castings into a water container, insert an air stone in the water bucket, and activate it. Leave the air stone active for at least three days and up to four.

When to Use Worm Compost Tea

While brewing your worm tea, you need to check it regularly and stir. The process of circulating water is to aerate worm tea and encourage the growth of beneficial microbes. Since these microbes begin to die as soon as aeration is stopped, you should use your tea within 16 hours at the most.

Brewed worm tea has a significantly higher population density of microorganisms than the extracted worm tea. Thus, worm tea is a good food source for plants. It helps increase plant life and prevent plant disease while imparting various other benefits for both the soil and the plant.

Once the brewing process is complete, you'll notice foam on the top of the worm compost tea. Additionally, the tea should be light brown in color. Lastly, smell the worm tea to ensure there is no strong odor. A pungent smelling worm tea could indicate that it has somehow been contaminated. In that case, you should brew a new compost tea and discard the old one.

Your worm tea will be most effective when it is first brewed. The potency of worm casting tea only decreases over time. Beyond 16 hours, the benefits of any compost tea will drop substantially. However, if you find you have any remaining tea after a thorough application, you can try to save it. We recommend storing any remaining tea in a shady place and using it within 24 hours.


Worm cast tea is a suitable alternative for chemical fertilizers as it is essentially an all-natural liquid fertilizer. Unlike the chemical counterparts, it does not cause plant roots to burn if used in excess. You can either buy or make worm compost tea by yourself. Worm compost tea is a beneficial soil amendment because it can stimulate microbial activity in the soil.

Besides being rich in nutrients and beneficial microbes to improve soil structure, worm compost tea helps your plants produce more foliage and more rigid stems. You can use it for a larger area for your plantation or simply use a watering can for your veggie garden.
