Know before you buy
The high phosphorus content (15%) is specifically designed to stimulate root development and support the production of flowers and fruits. Because it contains very little nitrogen and no potassium, it is best used as a targeted amendment rather than an all-purpose fertilizer.
Bone meal is most effective when mixed into the soil at the time of planting, especially for bulbs, trees, and shrubs. It can also be top-dressed around established plants during the early stages of their growth cycle to encourage stronger root systems.
Yes, Down to Earth Bone Meal is certified organic. It is a natural source of phosphorus and calcium, making it a reliable choice for organic vegetable growers looking to improve soil health and crop yields.
While it is excellent for bulbs, flowering plants, and trees, it is not a complete fertilizer. Since it lacks potassium, you may need to supplement with other organic fertilizers if your soil is deficient in a broader range of nutrients.
For the best results, mix the granules directly into the planting hole or the top few inches of soil. This ensures the nutrients are accessible to the root zone where they are needed most for establishment and growth.
