Spraying Compost Tea

https://organicentourage.com/
To help fend off powdery mildew and other diseases, along with providing additional nutrients, we spray every one or two weeks with a tea that we brew up from organic worm castings. If you notice, we're using a standard brass hose nozzle. Sometimes when the tea is really thick and plugs up even this nozzle, we'll just install a plastic hose ball valve and pinch off the spray a bit. In other words, even using a 400 mesh bag to hold the compost, the tea will plug up most nozzles. Using a nozzle or ball valve prevents this along with making the leaves "dance" when being sprayed so both sides get covered.
