Sustainably sourced and finely ground, our Fish Bone Meal is steamed and sanitized for safety, then blessed with elemental intention to promote blooming, branching, and beautiful yields.

Why Use Fish Bone Meal?

Unlike traditional bone meal, fish bone meal delivers higher phosphorus and added nitrogen, making it ideal for:

Boosting flower and fruit development

Strengthening root systems in vegetables and bulbs

Supporting microbial activity and soil structure

Preventing blossom-end rot with a natural source of calcium

Fish bone meal is particularly effective in acidic or biologically active soils, where slow-release phosphorus becomes bioavailable over time through microbial interaction.
