Wild-Caught White Fish Bone Meal — Organic Phosphorus & Calcium for Roots, Blooms & Vermi Systems
Wild-Caught White Fish Bone Meal is made from the bones of wild-caught marine white fish, processed gently to preserve nutrients without additives. With an NPK of 4-14-0, it’s a natural source of phosphorus, calcium, and trace minerals, supporting strong root development, healthy blooms, and resilient plant growth.
Gardening Use
Fish bone meal is a trusted amendment for gardeners seeking natural, slow-release phosphorus. It promotes deep root systems and vigorous flowering.
-
Use 1–2 tablespoons per gallon of soil for potting mixes.
-
Apply 2–3 lbs per 100 sq ft in garden beds, lightly mixed into the top few inches of soil.
It’s ideal for flowering plants, fruiting crops, and long-term soil building.
Worm Bedding & Vermicompost Use
In worm bins, fish bone meal acts as a microbe-feeding amendment that helps produce nutrient-dense worm castings. It also serves as a natural grit source, aiding worm digestion. Add 1/4 cup per gallon of your worm bedding mix to boost the phosphorus and calcium content of your finished castings.
