Know before you buy
This ratio is specifically formulated to prioritize phosphorus, which is essential for strong root systems, vibrant flower production, and fruit development. With 15% phosphorus, it provides the necessary nutrients to help your plants thrive during their blooming and fruiting stages.
Greenway Biotech's bone meal is a slow-release fertilizer that provides consistent nourishment for up to four months. Because it breaks down gradually, you don't need to reapply it frequently throughout the growing season.
It is highly effective for bulbs, vegetables, trees, and shrubs. However, because it is a phosphorus-heavy fertilizer, it is best suited for plants that are actively flowering or fruiting rather than those grown primarily for foliage.
This fertilizer is gentle on soil pH and is most effective when used in soil with a pH of 7.0 or lower. It is designed to improve soil biology and structure without causing drastic swings in acidity or alkalinity.
For the best results, mix the granules directly into the soil at the time of planting to ensure the nutrients are accessible to the roots. For established plants, you can work it into the top layer of the soil around the base of the plant.
Yes, this fertilizer contains 24% calcium, which is a critical nutrient for preventing blossom end rot in crops like tomatoes and peppers. By fortifying the plant's cell walls, it helps ensure healthier, more resilient fruit.
