Autumn-Gem 4-2-16 Foliar Fertiliser is a professional-grade liquid fertiliser formulated specifically for use in the autumn period to harden turf, improve colour, and build resilience ahead of winter. With a low nitrogen content and a high potassium ratio, this foliar feed strengthens cell walls, enhances root development, and improves disease resistance without promoting excessive soft top growth.
Supplied in a 10L container, Autumn-Gem is designed for use by groundskeepers, landscapers, and lawn care professionals looking to maintain high-quality turf performance as the growing season slows. Applied via foliar spray, it delivers fast-acting nutrients directly into the plant, giving your turf the support it needs when root uptake slows in cooler conditions.
