Cornmeal tea (some call it cornmeal juice) is a natural fungal control for use as a soil drench or a foliar spray in any kind of sprayer. Make by soaking horticultural or whole ground cornmeal in water at one cup of cornmeal per 5 gallons of water. Putting the cornmeal a nylon stocking bag to hold in the larger particles is one method, but I usually just toss the cornmeal in the water, stir it well and let sit for an hour or so and then strain out the solids. The milky juice of the cornmeal will permeate the water and this mix should be used without further dilution. This “tea” can be mixed with compost tea, Garrett Juice or any other natural foliar feeding spray.
