Tips for maintain your lawn in winter:
1. Water
You don’t need much water in winter compared to summer. Simply turn off water (irrigation) and only water the lawn as required.
2. Mowing height
It is very important to change lawn height as weather change as like you can do shorter in summer and leave bit longer in winter. Many lawn varieties across Australia are summer. Their growth slows down as temperature drops down. By allowing the leaf to grow longer, the lawn will be able to better block out w**ds and retain its colour for longer, but make sure you don’t leave too long between two mows. This will help avoid scalping of the lawn, causing it to brown the leaf.
3. Time to services Machines
During winter your lawn mower will have bit more break as you will increase gap between two mows, means you got chance to service your mower and other equipment. It is very important to change Blades, check air filter, change oil, clean or replace spark plug or tighten the bolts.
4. W**ds and fertilisers
Take a action against w**ds. Best things to do is apply pre-emergent herbicide which will stop w**ds to grow or All purpose w**ds control which will kill any w**ds are already grown in to your lawn. Make sure you read the labels as all herbicides are not suitable to some lawns.
Granular fertiliser will not be effective in winter compared to liquid fertiliser. Once soil temperatures drop below 14 degrees Celsius your grass will start to slow down and go semi-dormant for the cool months ahead. This is how warm-season turfgrasses protect themselves from the harsh conditions of winter. Because most grasses in Australia are warm-season varieties, they never really go fully dormant and will continue to grow but at a much slower rate. It’s for this reason, that they still have the capacity to take up some nutrients (more so in the northern states) which will be beneficial for keeping them strong through winter.
The key ingredients you will find in increased amounts in most winter fertilisers are potassium and Iron. Potassium provides strength to the whole plant and helps with cell function. Iron helps to strengthen your grass as well and also improves leaf colour. Provided you have fertilised in Autumn and have your lawn well prepared for winter, your lawn can go without fertilising again until spring. In some warmer states you might want to look at doing another application after about 8 weeks, usually around July. Foliar fertiliser applications are more effective than granular during this time, as the nutrient can be absorbed through the leaf. Be mindful however, that you won’t see much improvement with your lawn during winter if soil temps are below 14 degrees Celsius.
5. Avoid Compaction
Compaction can be a bit of a problem over winter, particularly in high wear areas, or if you have a bit of wet weather. Try to avoid traffic on your lawn wherever possible, or regularly aerate any areas which cannot be avoided to help loosen the soil. The same applies after heavy rains, particularly if water tends to pool or the soil gets a bit waterlogged. This will help the air get to the root zone, allowing your lawn to breathe and avoid heavily compacted soil.
