The Complete Hills District Lawn Care Guide
Everything you need to know about keeping your lawn healthy and green across Sydney’s Hills District — from Castle Hill to Kellyville, Baulkham Hills to Cherrybrook.
Understanding Your Local Climate
The Hills District has a unique microclimate. Summer temperatures regularly hit 30-35°C, while winters are mild with occasional frost in low-lying areas. Rainfall is moderate but inconsistent.
Lawns here need seasonal attention — higher mowing in summer to shade the soil, aeration in autumn, weed prevention in winter, and slow-release fertiliser in spring. We structure our care programs around these local patterns so your grass gets exactly what it needs, when it needs it.
Best Grass Types for the Hills District
Sir Walter Buffalo
The most popular choice in the Hills District. Drought-tolerant, soft underfoot, and performs well in both sun and shade. Mow at 30-50mm.
Empire Zoysia
Excellent for modern estates in Kellyville and The Ponds. Fine-textured, slow-growing, handles high traffic. Mow at 20-40mm.
Sir Grange Zoysia
Premium option for Bella Vista and Norwest. Extremely drought-tolerant with a fine leaf. Mow at 15-30mm.
Couch (Bermuda)
Fast-growing grass that produces the best stripe patterns. Common in established suburbs like Baulkham Hills and North Rocks. Mow at 15-30mm.
Kikuyu
Found on larger blocks in Glenhaven and Parklea. Very hardy and fast-growing with excellent drought tolerance. Mow at 25-40mm.

Common Lawn Problems in the Hills District
African Black Beetle
Grubs eat grass roots in spring. Signs include spongy turf and birds pecking at the lawn.
Winter Grass
A persistent cool-season weed. Treat with selective herbicide in autumn before germination.
Brown Patch
Fungal disease in warm, humid conditions. Improve drainage and reduce watering frequency.
Thatch Build-up
Dead grass layer common in kikuyu and buffalo lawns. Core aeration in autumn breaks it down.
