It's officially Spring - well almost!
Author: Stefan Palm Date Posted: 26 August 2020
After what feels like a wet, cold and frosty Winter, it's exciting to see a couple of days creep into the 20's this week! While Spring is officially a few days off, it certainly feels like Spring in the Air. So what does this mean for your lawn?
Spring is by far the best time of year for lawns – with the combination of warmth and rain, lawns literally jump out of the ground. It’s the season for installing instant turf, sowing seed, fertilising, repairing damage and renovation works like coring, scarifying and topdressing.
This Winter has been particularly cold and frosty. If you have a couch, kikuyu or buffalo lawn, this would mean that you may have lost a fair bit of colour bought on by the repetitive freezing of the lawn blades. This year, we've had a lot of frosty mornings so for many lawn lovers, Spring can’t come quick enough! As the ambient temperatures increase, so too does the soil temperature which is what triggers lawn to climb out of Winter dormancy. While I've already seen some improvement in our display lawns, recovery times will usually extend through September into October.
How quickly will lawn take to regain its colour?
It depends a few things including the variety and how quickly it warms up but it will typically look like this:
- Kikuyu will be fast to regenerate colour, showing good progress from early September
- Couch will take a little longer, starting its journey from mid September
- Buffalo is the slowest, often not getting going till late September, even early October.
What should you do now?
Fertilising: When it comes to Spring fertilising, I suggest you hold off for now. Ground temperatures have not risen enough so while you won't damage your lawn by fertilising now, you’ll get much better results if you wait till early October because that is when your lawn will be most active and best able to take up the nutrient.
Weed Control: Expect a flush of weeds as the Spring starts. The most common and prolific are the broad leaf type such as thistle, dandelion, creeping oxalis, chick weed etc. They will respond quickly to the warmer weather so be ready with some broad leaf selective herbicide such as Amgrow Bin- Die. Expect to see weeds like winter grass and sour sob disappear by themselves as they don't like the warmer weather.
Mowing: As temperatures increase, your lawn will start growing again so be ready for that. If you raised your mower a notch or two to preserve Winter Colour, its a good time to bring your mower back down to what it was before Winter started.
New Projects: If you’re planning on rolling out turf or sowing seed, now and right throughout Spring is a perfect time. The combination of mild warmth and rain are ideal conditions and make for fast establishment.
Happy gardening South Australia and welcome to Spring!
