Blood and Bone Fertiliser is a natural plant food that is great for improving the soil health, encouraging earthworms, and naturally feeding your plants. It can be applied liberally to the soil surface at any time of year or mixed with soil. It is perfect for mixing with soil when planting a tree or shrub and adding to the vegetable garden. The NPK rating is 6:6:0 and releases these nutrients in a controlled and slow manner. We recommend using one handful per shrub or 1-2 handfuls per square metre. Lawns respond well to this product and it should be used at one handful per square metre. In all instances, we recommend watering it in after application.
