McKays Slow Release Lawn Fertiliser

out of 5
(2 customer reviews)

To ensure the health and longevity of your grass, regular fertilising is required.

McKays Slow Release Fertiliser ensures a measured release of nutrients into the soil over many weeks. This can also be used as a starter fertiliser prior to or in combination with sowing of your grass seeds.

Components: Our fertiliser contains Nitrogen, Phosphorus, Potassium and Trace Minerals. See product breakdown in Description section below.

Frequency: We recommend fertilising your lawn every 3-6 months.

Distribution Rate:  30g per square meter (3kg per 100sqm).

Distribution Tip: Using our range of spreaders will assist in more even distribution and avoid clumping of fertiliser, which can burn the grass.
