Dirt Dynasty's vermicomposting worms naturally produce the world's best fertilizer just by living, eating and pooping. Plants depend on natural worm castings for nutrition and microbial health. Artificial fertilizer companies still have not been able to develop a better fertilizer. Unlike other fertilizers, vermicompost is odorless, non-toxic, long lasting and will not burn plants no matter how heavy-handed your application. Using our organic worm castings, you can apply less fertilizer less often and get better growth with no stinky fertilizer smell. Our castings are so good, it only takes about a tablespoon full to power a small potted plant for two months.
