Phos Mag fertiliser is a quality mix of NPK specifically designed to promote growth on trees, hedges and woody perennial plants. This mini-granular blend fertiliser offers an excellent spreading pattern which will release over a 6-week period. Phos Mag can be applied at any time of year provided the tree or plant is actively growing. While this fertiliser is most often used on trees and shrubs, it can also be used on areas suffering from a deficiency in phosphorus or magnesium.
The application rate will depend on how many times you intend to apply the product. If you require a detailed recommendation, then please contact us.
