Know before you buy
You can mix the granular castings directly into the soil when planting or top-dress them around the base of established plants. Gently work them into the top inch of soil and water thoroughly to help the nutrients integrate.
While these castings are excellent for improving soil health and vitality, they are best used as a soil amendment rather than a complete fertilizer replacement. They work most effectively when paired with a balanced feeding program to ensure your lawn receives all necessary macronutrients.
The nutrients in earthworm castings are released slowly as soil microbes break down the organic matter. This natural process ensures a steady, long-term supply of nutrients to the root zone rather than a quick, temporary burst.
Yes, they are 100% organic and certified for use in organic gardening. They are a safe, natural way to enrich your soil without the use of synthetic chemicals, making them ideal for vegetable gardens.
A 5lb bag is perfect for targeted applications, such as amending soil in specific vegetable beds or boosting the health of container plants. If you are planning to treat a large lawn, you may need multiple bags to achieve full coverage.
