Preparing your lawn for winter

Author: Stefan Palm   Date Posted: 3 May 2016 

As we get into the later part of Autumn, you may have noticed your grass starting to slow down. If you have a warm season grass (ie couch, kikuyu or buffalo), as the weather gets cooler your lawn will start going into winter dormancy. Warm season grasses grow during the warm weather and virtually stop growing during the cold weather.

There are some things that you can do now to prepare your lawn for winter to ensure it stays as healthy and green as possible.

One thing you should do now is raise your mower height – by one notch. This will leave more blades present on your lawn which will add to the overall “greenness” of your lawn. It will also make it a lot less likely for you to scalp your lawn. Scalping is where you cut your lawn too low, effectively removing all the blades and leaving those familiar brown swirl marks from your mower. During the warm weather, your lawn will quickly recover from this because it is actively growing but because your lawn will virtually stop growing during the cooler months, it won’t be able to grow back any new blades till spring.  My advice to you is within the next few weeks, raise your mower height by one notch and keep it on this setting till the end of September. As soon as Spring starts,  take it down to where it was prior to winter.

Another thing you can do if you haven’t already is fertilise your lawn. Fertilising in Autumn helps your lawn stay greener in winter but it also gives your lawn some extra nutrient to store up during the winter months which gives it something to get started on when it comes out of dormancy.  This really makes a difference in the spring. Use a mineral fertiliser high in potassium.

Lastly, make sure you remember to adjust your watering system. If it’s automated, reprogram your computer to compensate for the extra rain around – you don’t want to over do the water in winter as it will only lead to problems.

Outside of these things, your lawn will most likely take care of itself during winter with very little input from you. If you do happen to notice irregular areas of lawn dying off, take a core sample and bring it down to us as soon as possible. This is not normal, even for winter and should be attended to.
