Vitax Bonemeal Garden Fertiliser 10kg Tub - High-Phosphate Organic Slow Release NPK 3.5-20-0 - Promotes Deep Root Development for Bulbs, Roses, Fruit Trees and Shrubs - Sterilised Bonemeal

Root failure at establishment is the most common cause of plant loss after transplanting - and the most preventable. Vitax Bonemeal is an organic slow-release fertiliser with an NPK of 3.5-20-0, making it one of the highest-phosphate garden fertilisers available for UK growers. The extremely high Phosphate content of 20% is specifically targeted at root cell development and the formation of the extensive, deep root systems that allow newly planted trees, shrubs, roses, bulbs and perennials to establish quickly, anchor firmly and access soil moisture effectively throughout their first growing season and beyond. Produced from sterilised bonemeal, this organic fertiliser releases Phosphate and Nitrogen slowly and steadily over an extended period as the bone material breaks down naturally in the soil. This prolonged release window is what distinguishes bonemeal from fast-acting phosphate fertilisers - rather than delivering a single concentrated dose that plants may not be able to absorb efficiently, the nutrients become available progressively as root systems develop and demand increases. The natural Calcium content of bone provides additional structural support for cell walls and root tissue, contributing to the overall physical strength and resilience of the developing plant. Vitax Bonemeal is the specialist choice for planting bulbs, establishing roses and perennials in spring, planting young fruit trees and bushes at the start of the season, and as an autumn top dressing around established fruit trees and soft fruit bushes ahead of winter dormancy. Apply by mixing 100 to 150g per square metre into the soil before sowing or planting, or by working it into the planting hole before setting in the plant. The 10kg tub treats up to 100 square metres as a planting preparation dressing, making it ideal for gardeners with multiple beds, borders, or a productive kitchen garden to prepare each season. Beyond new plantings, Vitax Bonemeal can be applied as a top dressing to established roses and border plants in spring and around fruit trees and bushes in autumn to replenish phosphate levels before the demands of the new growing season begin. The high phosphate level supports not only root development but also the energy-intensive processes of flowering and fruiting - phosphate governs the plant's ability to produce and transfer the energy compounds that drive flower bud initiation and fruit development from root to shoot. Suitable for use in garden beds, borders, raised beds, allotments, pots and large containers.
