Worm Nerd’s Worm Tea Concentrate is the ideal formula for lawns, orchids, houseplants, and more. Worm tea is made by collecting beneficial nutrients and microbes from the worms’ waste and urine with water. Because of the nutrients and live, microorganisms, it’s also a natural fungicide and pesticide that builds up plants’ immune systems to insects and disease. Simply dilute with non-chlorinated water before applying directly to plants or soil.
