How to keep lawn green through winter

As we are in the cooler months, our lawns in South Australia will slow in growth and can lose some colour. This is mainly due to the drop in soil temperatures and the reduced amount of direct sunlight. 

Most of the common grasses here in Australia are warm-season grasses. This includes Buffalo, Couch, and Kikuyu. This means they thrive through the warmer months and in winter will reserve energy until warmer weather arrives.

In some spots around SA, we don’t just get cold, we get FROST!


Frosts cause damage to turf when the moisture inside the leaf blade freezes and expands. This causes the cell wall of the grass to rupture, damaging the turf. Frost can also cause significant discolouration to the leaf as the damaged cell walls slows down photosynthesis.

Once the weather starts to warm up again in spring, the lawns can repair and re-grow, returning to their lush green pre-winter condition.

BUT, you don’t have to settle for colourless lawn through winter. Products like Iron Guard Plus and Colour Guard Plus can give your lawn a helping hand in maintainng its lovely green colour.

Iron Guard Plus

Iron Guard Plus is a turfgrass-enhancing bio-stimulant that contains iron and amino acids, formulated to provide a boost in colour and turf strength.
