Know before you buy
This formula is specifically balanced with an 8-0-5 NPK ratio to prioritize root development and stress recovery over top-growth. By focusing on potassium rather than high nitrogen, it helps your grass store energy for the winter months and ensures a faster, healthier green-up when spring arrives.
No, this is an organic, slow-release formula that is designed to be non-burning. Unlike synthetic fertilizers that release nutrients all at once, this granular feed breaks down gradually, making it safe for your grass even if the application isn't perfectly uniform.
The absence of phosphorus is intentional and often preferred for established lawns. Many soils already contain sufficient phosphorus, and omitting it helps prevent runoff into local waterways while keeping the focus on potassium for overall plant resilience.
Because this is a slow-release organic fertilizer, it works in harmony with soil microbes to break down nutrients over time. You won't see an immediate, artificial surge in growth, but you will see sustained, consistent nutrition that supports long-term soil health.
While this product is excellent for established lawns, it is best used once the new grass has been mowed at least three or four times. For brand-new seedlings, we recommend using a dedicated starter fertilizer until the root system is fully developed.
