What is Fish, Blood & Bone Fertiliser?
Fish, Blood & Bone Fertiliser is an organic-based fertiliser composed of fish meal, dried blood, and ground bone. This blend provides essential nutrients—nitrogen (N), phosphorus (P), and potassium (K)—in a balanced ratio, specifically NPK 5-5-6. The nitrogen promotes lush, green foliage; phosphorus supports strong root development; and potassium enhances flower and fruit production. Its organic composition ensures a slow release of nutrients, feeding plants over an extended period and improving soil structure.

Suitable for a wide range of plants, including flowers, vegetables, shrubs, and lawns, making it a go-to fertiliser for various gardening needs.
