Sterilised Bonemeal is a tried and trusted organic fertiliser that provides both phosphates and nitrogen, the two nutrients essential for healthy plant growth. These nutrients are released slowly and steadily, making Vitax Bonemeal an ideal fertiliser for bulbs and herbaceous plants, shrubs, roses, fruit trees and strawberries. It can be applied prior to sowing or planting and can be used throughout the season as a top dressing for roses and fruit trees.
