15% Slow-Release Phosphorus
Phosphorus from bone meal releases through soil microbial activity — not water solubility. This means steady, sustained feeding that lasts weeks longer than synthetic phosphorus sources.
24% Calcium Built In
Bone is primarily calcium phosphate. Every application delivers 24% calcium that prevents blossom end rot in tomatoes and peppers, strengthens cell walls, and improves fruit quality.
Root Development Powerhouse
The go-to organic amendment for transplant establishment, bulb planting, and new tree installations. Phosphorus in the root zone drives immediate root extension and anchorage.
Bloom Booster for Organic Gardens
Roses, perennials, and flowering shrubs respond to bone meal with increased flower bud formation and larger, more vibrant blooms. The organic alternative to synthetic bloom boosters.
Feeds the Soil Biology
Unlike synthetic phosphorus, bone meal feeds soil microbes as they break it down. Healthy microbial populations improve overall soil health, structure, and nutrient cycling.
Per-Hole or Per-Bed Application
1–2 tablespoons per planting hole for transplants and bulbs, or 2.5–5 lbs per 100 sq ft broadcast and incorporated for beds. Flexible for any planting method.
OMRI-Compatible Organic Input
Steamed bone meal is approved for organic production. Safe for certified organic gardens and farms following NOP guidelines.
