When brewing compost tea use only quality, pathogen-free
compost or worm compost. If you brew the tea from
compost that has pathogens, you will then spread those
to your plants.
Use only pure water for the tea. City water can contain

showed promise, the results havent been consistent.
Chase says people should do their own experiments and
