Leaf compost tea is a nutrient-rich liquid fertilizer made from steeping composted leaves in water. It has a limited shelf life, typically lasting between 24 to 48 hours after brewing. To ensure maximum effectiveness, use it as soon as possible for watering plants or as a foliar spray.
How Long Does Leaf Compost Tea Last?
Leaf compost tea is best used fresh, ideally within 24 to 48 hours of brewing. The microbial activity that makes compost tea beneficial for plants decreases significantly after this period. As the tea sits, beneficial bacteria and fungi begin to die off, reducing its effectiveness. For optimal plant health, use the tea promptly after preparation.
Why Use Leaf Compost Tea?
Leaf compost tea provides several benefits for plants and soil:
- Nutrient Boost: It supplies essential nutrients like nitrogen, phosphorus, and potassium.
- Microbial Enrichment: Enhances soil microbial life, improving soil structure and plant growth.
- Disease Suppression: Helps protect plants from diseases by introducing beneficial microorganisms.
- Eco-Friendly: A sustainable alternative to chemical fertilizers, promoting organic gardening practices.
How to Make Leaf Compost Tea
Ingredients
- Composted Leaves: Fully decomposed leaves provide the best results.
- Water: Use chlorine-free water to avoid killing beneficial microbes.
- Optional Additives: Molasses or seaweed can boost microbial growth.
Steps
- Fill a Container: Place composted leaves in a breathable bag or directly into a container.
