Yes, it’s absolutely safe. All J Arthur Bower's Bone Meal is produced under strictly regulated conditions and is heat-treated and sterilised to kill all harmful organisms. There is no risk to your garden or to humans or pets. Bone Meal is a slow-release source of phosphates, which stimulate root growth, and also contains valuable calcium. You will see that it is an essential ingredient in most of our recommended Planting Mixtures. As Bone Meal is rather light and dusty, take care when using it in windy conditions.
