Autumn Lawn Care 101
Autumn in Australia marks a crucial transition for our lawns. As the warmth of summer fades, we must shift our focus to preparing our turf for the cooler months ahead. For most Australian lawns, comprised of warm-season varieties like Buffalo, Kikuyu, Couch, and Zoysia, autumn is the last chance to build strength before winter dormancy. At Lawn Doctor, we understand the unique challenges of Australian lawns, especially in Perth, and we're here to guide you through these essential autumn care steps.
Here's a comprehensive guide to maximising your lawn's winter resilience:
Clear Debris & Minimise Shade
As leaves fall and days shorten, ensure your lawn receives ample sunlight—regularly clear fallen leaves and debris to prevent them from smothering the grass.
Reduce shade from outdoor furniture and shade sails. Remember that at least four hours of direct sunlight is ideal, particularly for varieties like Sir Walter Buffalo.
Prune trees and shrubs to maximize sunlight exposure. Consider planting deciduous trees for optimal winter sunlight.
2. Pre-Emergent Weed Control
Autumn is prime time for cool-season weeds to germinate. Act proactively with a pre-emergent herbicide.
Winter Weeds compete for nutrients; therefore, a strong pre-emergent program is vital.

3. Raise Mower Blades & Maintain Regular Mowing
Gradually raise your mower height to around 40mm, especially in shaded areas. This promotes thicker growth and helps block weeds.
Continue regular mowing to remove weed seed heads and prevent future germination. Mowing at around 25mm is acceptable in sunny areas.
4. Aerate & Decompact Soil
Summer activity compacts the soil, hindering water and nutrient absorption. Aerate your lawn using a garden fork or aerator sandals, especially in heavily shaded areas that retain moisture.
This is especially important in areas with heavy clay soils, which is common in Perth.
Decompaction prevents roots from rotting and ensures healthy growth.
5. Strategic Fertilisation for Winter
Fertilising in late April or May is crucial for winter resilience. Use a slow-release, granular fertilizer with iron, manganese, and trace elements.
Fertilising encourages strong root growth and helps the lawn compete against winter weeds.

6. Water Wisely
With increased rainfall, avoid overwatering. Water only when necessary, and do so in the early morning.
Avoid water logging, as this can cause root rot.
7. Lawn Pest Control
Be vigilant for pests like Armyworm, especially after humid periods.
Use contact or residual insecticides as needed. Residual products offer longer-lasting protection.
