How to Make a Compost Tea: 14 Steps
Compost tea is an organic, nutrient-rich liquid solution made by steeping compost in water. It is an excellent way to nourish your plants and improve soil structure. Here are 14 steps to make compost tea.
1. Gather materials: You’ll need quality compost, a large bucket or container, water (preferably not chlorinated), a fine mesh strainer or cheesecloth, and an air pump with tubing and an air stone (optional).
2. Choose quality compost: Select well-aged compost that is rich in organic matter, ideally homemade or sourced from a reputable supplier.
3. Use chemical-free water: If possible, use rainwater or dechlorinated tap water. Chlorine may kill the beneficial microorganisms in the compost tea.
4. Fill the bucket with water: A popular ratio is one part compost to five parts water, but feel free to adjust based on personal experience and preference.
5. Add compost to the bucket: You can place the compost directly into the water or wrap it in cheesecloth to create a “tea bag.”
6. Aerating (optional): If you’re using an air pump, connect it to the air stone and place it in the bucket. This will provide oxygen for beneficial microorganisms to multiply.
7. Stir regularly: Whether aerating or not, ensure that you stir the mixture frequently to help release nutrients from the compost.
8. Steep for 24-72 hours: The longer it steeps, the stronger the nutrients and microbial concentration will be in your tea.
9. Check on the progress: Observe any changes in color and smell of your developing tea. An earthy aroma indicates successful brewing.
10. Strain the mixture: Once you have reached your desired brewing time, pour the solution through a fine mesh strainer or cheesecloth to remove large particles.
11. Dilute the tea (if needed): Depending on the strength and your preferences, you may dilute the compost tea with additional water, typically at a 1:10 ratio.
12. Apply the tea promptly: To get the maximum benefits, use the compost tea within four hours as microorganisms start to die off.
13. Feed your plants: Pour or spray your compost tea onto the plant’s leaves and around its roots, ensuring it reaches the soil.
14. Clean up and store: Rinse all equipment thoroughly and let it dry to prevent any unwanted buildup. Store your tools in a cool, dry place to prolong their life.
By following these 14 steps, you’ll create a nutritious compost tea to help your plants flourish while contributing to sustainable gardening practices.
