PGF Green Machine – Liquid Iron & Nitrogen Lawn Fertiliser for Deep Green Colour | Year-Round

Want your lawn greener — fast? PGF Green Machine is a premium liquid lawn fertiliser combining stabilised nitrogen, iron and magnesium to drive deep, rich green colour through the leaf within days of application. Unlike granular fertilisers that rely on soil temperature and microbial activity to release nutrients, Green Machine delivers directly through the leaf — making it one of the most effective liquid fertilisers for keeping your lawn green in autumn and winter when other products slow down.

Available in 2L, 4L and 20L.

What Each Nutrient Does

Iron (Fe 6%) — the primary driver of deep green colour. Iron is essential for chlorophyll formation and gives that dark, lush appearance that separates a good lawn from a great one. It also helps lawn blades hold heat, keeping colour through cooler periods and improving disease resistance.

Nitrogen (N 14%) — fuels leaf growth and sustains the green colour response over time. Stabilised nitrogen in Green Machine means a more consistent, longer-lasting colour hit compared to standard urea-based products.

Magnesium (Mg 1%) — the central atom in every chlorophyll molecule. Without adequate magnesium, lawns can appear pale or yellowing even after nitrogen applications. Green Machine covers this often-overlooked deficiency.

Organic acids — improve the efficiency of every nutrient in the formula by enhancing uptake through the leaf and mobilising nutrients within the plant cell, so more of what you spray actually gets used.

When to Use Green Machine

Spring & Summer — use as part of a regular liquid program every 4–6 weeks to maintain vibrant colour and support active growth alongside your granular fertiliser schedule.

Autumn & Winter — this is where Green Machine really earns its place. As soil temperatures drop and granular fertilisers become less effective, a foliar liquid like Green Machine bypasses the soil entirely and feeds the plant directly. If your lawn goes dull and pale in the cooler months, this is the product to reach for.

Tip: For best winter results, tank-mix Green Machine with PGF Carbon King (humic and fulvic acids) to improve nutrient uptake efficiency even further. Together they form part of the PGF Liquids Bundle.

Iron stain warning: Iron-based fertilisers can stain concrete, pavers and hard surfaces. Avoid overspray onto driveways, paths and edging, and rinse any hard surfaces immediately if contact occurs.
