Brewing Compost Tea
Ingredients Needed
To brew compost tea, you will need the following ingredients:
- Non-chlorinated water (use rainwater, or allow tap water to sit for over 24 hours)
- 1-2 cups of inoculant (either worm castings or compost)
- ¼ – ½ cup of food source for bacteria or fungi
- 5-gallon bucket
- Compost tea brewer or air stones
- Aerating pump
- Stirring device
The Brewing Process
To begin, fill a 5-gallon bucket with non-chlorinated water. Add 1-2 cups of inoculant, either worm castings or compost, to the water. Then add ¼ – ½ cup of food source for bacteria or fungi to the mixture.
Attach air stones to an aerating pump and place it in the compost tea brewer. Dangle the air stones in the compost mixture, making sure that the pump is outside the bucket. Turn on the aerating pump and let the mixture percolate for 12-24 hours.
Stir the mixture occasionally to ensure that the compost is evenly distributed. After brewing, strain the tea through cheesecloth, pouring the mixture into another bucket.
To use the compost tea, apply it to the soil around your plants, either as a drench or a foliar spray. The optimum time of day to apply compost tea is in the morning, when plant stomata are open to receive it and the sun will dry leaves and prevent fungal diseases from excess moisture. Apply when soil is moist if using the product as a drench. For most ornamental plants, spray in late winter to early spring and again when leaf buds break.
It’s important to note that the temperature of the water during brewing should be between 60-80°F. If the water is too cold, the microbes won’t grow as quickly. If the water is too hot, the microbes may die off.
In conclusion, brewing compost tea is a simple process that can provide numerous benefits to your garden. By following these steps, you can create a nutrient-rich tea that will help your plants thrive.
Application of Compost Tea
Compost tea can be applied to plants in two different ways: as a foliar spray or as a soil drench. Both methods are effective ways to fertilize plants and provide them with the nutrients they need to grow and thrive.
Foliar Spray
A foliar spray is a method of applying compost tea directly to the leaves of plants. This method is particularly effective for plants that have a high nutrient requirement, such as tomatoes, peppers, and other fruiting plants. To apply compost tea as a foliar spray, simply fill a spray bottle with the tea and spray the leaves of the plants until they are thoroughly coated.
