Buffalo grass is a warm-season turf that goes dormant when temperatures consistently drop below 10C, which happens across Sydney's winter months. Understanding what your lawn needs during this dormancy period is critical to keeping it healthy and resilient so it bounces back strong in spring.
Why Buffalo Goes Dormant
The dormancy is completely natural and healthy. It's the grass's energy-conservation strategy. During winter, the plant redirects resources from above-ground growth to root development and winter hardening. The leaf tissue may look pale or dull — that's normal. Many homeowners panic and start overwatering or fertilising, which actually causes problems.
Watering: The Biggest Winter Mistake
Most gardeners overwater in winter. Dormant buffalo doesn't need much water. Check the soil moisture before watering: if it's damp 50mm down, don't water. Winter rainfall in Sydney usually provides enough moisture for a dormant lawn.
Overwatering dormant buffalo creates conditions for fungal diseases like dollar spot and take-all patch. The grass is growing slowly, water isn't evaporating as fast, and fungal spores thrive in cool, wet conditions. One of the most common issues we see is a homeowner with yellowing patches in July — and it's almost always from excessive winter watering.
Mowing Strategy for Winter
Reduce your mowing height from the usual 40-60mm to about 20-25mm. A shorter cut improves air circulation around the base of the plant, which reduces fungal pressure. Buffalo grows very slowly in winter, so you might only need to mow every 3-4 weeks instead of weekly.
If you're in a high-rainfall area, you might not need to mow at all during the coldest months. That's fine — dormant buffalo stops growing.
Watch for Fungal Issues
Despite best efforts, fungal problems can still develop in wet winters. Dollar spot appears as small yellowish patches. Rust looks like fine orange dust on the leaf surface. If you spot these, a targeted fungicide application usually sorts it out within a week or two.
Prevention is better than cure: good drainage, adequate air circulation, and avoiding overwatering are your best defences.
Early Spring Preparation
As temperatures start rising in late August and early September, your buffalo will begin waking up. This is when you bump mowing frequency back to normal and resume your regular feeding schedule. A spring fertiliser boost (balanced NPK, like 10-10-10) helps the grass green up and shoot quickly.
The grass will green up and grow faster than you might expect once it wakes. Within 2-3 weeks of consistent spring warmth, your lawn will look fully active again.
Key Takeaways
Winter buffalo care is about restraint, not intervention. Less water, less fertiliser, less mowing. Avoid fungal problems by maintaining good drainage and air circulation. Your buffalo isn't suffering — it's sleeping, and that's exactly what should be happening. Come spring, it'll reward you with vigorous growth.
