Frequently Asked Questions
What is compost tea good for?
Compost tea inoculates soil and plant surfaces with beneficial microorganisms. It can improve nutrient cycling, suppress some diseases, and enhance soil structure when applied regularly.
How long does compost tea last?
Apply compost tea within 4 hours of brewing while microorganisms are still active. Never store brewed compost tea as beneficial microbes die quickly without aeration.
