Organic Noshimuri Worm Tea also known as Vermicompost Tea, is an all natural liquid fertilizer made from fresh earthworm castings/manure & tanked rain water. Earthworms consume & recycle organic matter & food scraps, which then passes through the earthworms' body & exit. This results in natural organic castings/manure full of healthy microbes & nutrients that boost the plant health with vigorous growth.
