Allow your plants to get the nutrients they need & crave. Worm Nerd’s Worm Castings are a natural, chemical-free soil additive and fertilizer that increases the health of your plants. Composting worms voraciously eat yard waste and scraps of fruits and vegetables – the resulting excrement, or “castings”, is loaded with nutrients and results in higher yields, larger and better tasting vegetables, stronger flowers and blooms, and greener, healthier lawns. Follow the simple directions to amend topsoil or potting soil. We suggest combining a mix of 20% worm castings and 80% soil to create the ideal growing medium for your plants.
