Experience the remarkable benefits of our 4 lb bag of Organic Healthy Grow Worm Castings Garden Plant Food Fertilizer. Derived from earthworm castings, these castings offer a holistic solution for gardening success. Worm castings provide an excellent way to soften soil and increase microbial activity while giving plants a natural, easily absorbed source of nitrogen, calcium and iron. This results in faster growth, larger plants and bigger blooms. We use only single-sourced worm castings from a temperature and moisture-controlled environment in which the worms are counted and weighed every two weeks to ensure over 95% pure castings. Elevate your gardening experience with the power of worm castings. By utilizing worm casting plant food fertilizer in the fall, you enrich your soil, boost plant growth, and promote healthier plants for the upcoming growing season. The organic and nutrient-rich nature of worm castings makes them an excellent choice for enhancing your garden's soil health.
