What month is best to scarify a lawn in Australia?
The best time to scarify a lawn in Australia is September and April. These periods provide optimal conditions for recovery, as the grass is actively growing, temperatures are warm enough (above 16 °C), and sufficient moisture to support regrowth.
What is the difference between dethatching and scarifying a lawn?

Dethatching is a lighter process that removes the surface layer of thatch using metal prongs or tines, which is ideal for lawns with moderate buildup. In contrast, scarifying is more aggressive, using blades to cut deeper into the soil to remove thick thatch layers, moss, and debris while creating grooves for better aeration and nutrient absorption.
