Maxwell Planting Fertiliser 3-16-9+5%MgO 20 kg

The Maxwell Amenity Planting Fertiliser has a high content of slowly soluble phosphate, plus high levels of potash and magnesium which is ideally suited for root development and growth; very important in the early stages of growth, especially in difficult soils such as reclamation sites, sand or high organic soils.

Its slow solubility resists leaching and extends its availability. Only one application per season is necessary. Safe for use on all trees and shrubs including lime-hating species such as rhododendron and azaleas.


How to Use Maxwell Planting Fertiliser

Seed bed and lining out - Apply Maxwell Planting Fertiliser at recommended rates and work into the top soil before sowing or planting.

Shrub/Tree planting - Top dress at planting or as growth commences in the spring. For pit planting, mix with soil and/or peat in the planting hole or pit. For semi-mature shrubs or trees, apply as a top dressing to the root ball area, plus one metre out.

Mature Trees/Shrubs - The top dressing should cover the whole rooting area plus at least one metre beyond the spread of branches or run-off point.

When to Use

Maxwell Planting Fertiliser can be used at anytime during the growing season, but for maximum benefit, applications should be made as growth commences in the spring.
