Carbon Gold Tree Fertiliser 10kg is a premium, organic fertiliser designed to enhance the health and vitality of trees, shrubs, and woody plants. This unique blend combines enriched biochar with potassium phosphite, mycorrhizal fungi, seaweed, and organic wormcasts to create a powerful soil amendment that promotes robust root development, improves nutrient uptake, and increases resistance to environmental stresses.
The biochar component enhances soil structure, increases water retention, and provides a habitat for beneficial soil microorganisms. Potassium phosphite delivers essential nutrients and stimulates plant defences against pathogens, while mycorrhizal fungi and wormcasts contribute to a healthy soil microbiome. This fertiliser is ideal for use in challenging conditions, including replanting in diseased soils or supporting veteran trees.
