Is it still a good time to sow lawn seed?

It's been an unusual Autumn weather wise. We haven't had a lot of rain and the warm weather seems to be hanging on - many people are asking; "Can I still sow lawn seed?"
The answer is both yes and no. Late April is too late to sow varieties like couch and kikuyu because these types slow down and become dormant during the cooler months. There isn't enough time left to germinate and establish them before Winter. Having said that, it is an ideal time to sow cool season grasses like fescue, rye and bluegrass. These varieties love this kind of weather and will germinate and cover quickly.
While these varieties are not particularly suitable for South Australia's hot, dry climate when sown by themselves, they make for excellent oversowing varieties over lawns like couch, kikuyu and buffalo.
Oversowing can be a real handy solution if you find yourself with a patchy or poor looking lawn now leading into Winter. As lawns like kikuyu, couch and buffalo start transitioning into Winter dormancy, you can find that they can become patchy and colourless. Oversowing is often overlooked as a means to improve a lawns appearance however it can be a really good way green up your lawn now and through the Winter months. If you're looking to sell your home, it's a fantastic way to green up a lawn quickly.
For oversowing couch:
Use fine leaf rye. This variety has a fine blade similar to couch and will blend in really well. It's shade tolerant and will look good now and right through Winter. Germination typically takes 10-14 days at this time of year.
For oversowing kikuyu and buffalo:
Use tall fescue. Once mature, Tall fescue has a broad blade, similar in colour and texture to these varieties and like fine leaf rye will germinate now and look good throughout Winter. Germination typically takes 10-14 days at this time of year.
Autumn is an excellent time to sow cool season grasses but its best to act quickly. While you will still get germination during Winter, you will get much faster results now while there is still some warmth around.
