There are a variety of factors that affect grass growing conditions, such as, sunlight, moisture and temperature.
We can all joke about a Townsville winter as it is a far cry from the cold and frost experienced in southern cities and states. Undoubtedly, it is the best time of year in North Queensland with glorious days and crisp nights.
Whilst, we certainly cannot compare temperatures, the shorter days and colder nights can slow down grass growth. String some cold nights together and the soil temperature drops as well. The grass will be almost dormant, hibernating until the weather begins to warm again.
This is the reason that you can shift from mowing your lawn every seven days to every fortnight or three weeks over Winter.
Whilst the grass is asleep, the older grass leaves will die in continuous cold weather causing the lawn to look brown (just like deciduous trees that regrow their leaves in Spring). Cold wind can cause the grass blade to lose its moisture. Given the opportunity weeds can take advantage of the lawn’s weakened state to fill every possible gap.
Our first recommendation would be to not treat your troubles in winter. An all-out assault on weeds when your grass is not actively growing will leave your lawn weak and vulnerable.
The most important thing is to get your lawn healthy BEFORE Winter as a healthy lawn will always try to outcompete any invasion of weeds.
Ideally, do all fertilising, herbicide application, aerating and topdressing before Anzac Day. Otherwise, we recommend that you wait until the first week of August.

Write something about yourself. No need to be fancy, just an overview.
