While many States of Australia plunge in temperature, there are many (lucky?) states that are still moderate or hot throughout winter. See below for general tips during Winter:
VICTORIA
While some cool season seed will still germinate in lower temperatures it’s not ideal sowing time in Victoria. Fix patches if you need to and then wait until the warmth comes back in Spring before sowing any large projects.
TASMANIA
It’s cold in Winter so our advice for Tasmania is similar to that for Victoria… Spring time is a better time to get the results you’re after for lawn projects.
NEW SOUTH WALES AND ACT, SOUTH AUSTRALIA
While some areas will be copping the cooler temps it might still be possible to sow some cool season grasses (that’s ryegrasses, fescues etc…)
If you’re in more Northern areas then it might be possible to sow warm season couch or kikuyu – but you’ll need consistent night time temps over 20 degrees.
QUEENSLAND, WESTERN AUSTRALIA, NORTHERN TERRITORY
Keep on sowing warm season grasses if you’re in a warm or hot area! Cool season grasses go well in Brissy and South.
