N-Mag Lite 4-12-10 + 4MgO Planting Fertiliser is a premium, slow-release fertiliser specifically formulated to support successful tree, shrub, and woody plant establishment. Designed for use at planting, it delivers a carefully balanced supply of essential nutrients directly to the root zone, helping newly planted stock establish quickly and develop strong, resilient root systems.
The low nitrogen, high phosphate formulation promotes root initiation rather than excessive top growth, making it ideal for young trees and shrubs during the critical establishment phase. Added magnesium (MgO) supports chlorophyll production, improving leaf colour and overall plant vitality, particularly in poor or nutrient-deficient soils.
N-Mag Lite’s controlled, slow-release technology ensures nutrients are released steadily over time, reducing leaching and minimising the risk of scorch or over-feeding. Widely used by professional landscapers, forestry contractors, and local authorities, it is suitable for urban tree planting, woodland creation, shelterbelts, and large-scale landscaping projects where reliability and long-term performance are essential.
