Sinclair Bonemeal (25kg)

A traditional, slow-release organic fertiliser (NPK 3.5-18-0) exceptionally high in phosphorus to provide the ultimate foundation for strong, deep root systems and healthy establishment.

• Targeted Root Development: The high phosphorus content makes this the premier choice for use at the time of planting, ensuring trees, shrubs, and perennials anchor quickly and thrive.

• Extended Slow-Release: Naturally breaks down over several months, providing a steady, long-term supply of nutrients that won’t leach away or overwhelm young plants.

• Organic Soil Enrichment: Derived from natural sources to improve soil structure and fertility, supporting a healthy environment for long-lived plants and bulbs.

• Essential for Planting & Moving: Perfect for “watering in” new hedges or when moving established plants to minimize transplant shock and encourage rapid recovery.

• Bulb Specialist: An ideal additive when planting spring or autumn bulbs, providing the specific nutrition needed for reliable flowering year after year.

General Application Rates:

• Planting Trees & Shrubs: Mix 140g–200g into the backfill soil of the planting hole.

• Bed & Border Preparation: Apply 70g–140g per m² and rake into the top 10cm of soil.

• Bulb Planting: Mix a small handful into the soil at the bottom of the planting trench.
