Identification & next steps ↗Review previous grub damage and local egg-hatch timing. Confirm the larval target before planning protection.
Identification & next steps ↗Plan for annual summer grass before seedlings emerge. Remove or identify existing weeds first.
Identification & next steps ↗Review traffic routes, soil structure and recovery potential before planning renovation.
Identification & next steps ↗Typical watch windows, not a live outbreak map or a spray calendar. Conditions can occur outside these months and across state borders. Grass type, recent weather, irrigation and a confirmed diagnosis take priority. For a site-specific program, email sales@turfmate.com.au.

Break the area into rectangles and triangles, subtract beds and paths, and record the total in square metres. An accurate area is the starting point for product planning and label rates.
Find a lawn program ↗Compare moisture in healthy and stressed areas before changing irrigation. Review drainage and water penetration. Disease, dry patch and root-feeding pests can all look like a watering problem.
Investigate dry rings ↗Take a wide view, a fresh patch edge and a close-up of the leaf, weed or insect. Add your grass type, site climate, recent weather and treatment history. A photo is a starting point; some problems need a sample.
