Fish Bone Meal Organic Fertilizer – High Phosphorus for Blooms

Coast of Maine Fish Bone Meal (5-13-0) is made by dehydrating and grinding fish bones into a granular meal. The process concentrates phosphorus, calcium, and nitrogen from the fish bones while preserving naturally occurring trace minerals and micronutrients. Fish Bone Meal provides an alternative to traditional steamed bone meal that retains more of the original nutrient profile.

With 18% calcium and high phosphorus (13%), Fish Bone Meal is well matched to the nutrient requirements of budding and blooming plants. It is OMRI listed for use in certified organic gardens and is preservative-free. Apply outdoors in spring after the weather warms for best results.

Who Should Use This Fertilizer

Fish Bone Meal is suited for organic growers who want a natural high-phosphorus fertilizer for flowering and fruiting stages. Its OMRI listing makes it appropriate for certified organic programs. It works well as a soil amendment mixed into beds, as a transplant hole addition, or as a top dressing during the budding phase.

Phosphorus and Bloom Development

Phosphorus (P) is a primary macronutrient involved in energy transfer, root development, and reproductive growth — including flowering and fruiting. During the budding and bloom stages, plants increase their demand for phosphorus relative to vegetative stages. Fertilizers with higher P values (the middle number in an N-P-K analysis) provide the additional phosphorus needed to support flower development and set.
