The Steps To Increasing Lawn Health In Autumn
Realise and be aware of the importance of the lead-up to Winter as being the only time to create a beautiful Winter lawn and act accordingly.
Increase Mowing Heights
As daylight hours decrease so does the ability of lawns to photosynthesise, by increasing mowing heights and leaving more green leaf we increase the food supply to the grass. This step is essential, and taking the mower up a notch or two should suffice.
Decrease Watering as Air and Soil Temperatures Decrease
Over watering at this time of year can increase the possibility of turf diseases or rotting of the thatch layer.
Treat Wintergrass
If we had Wintergrass last year, we’ll have it again this year too, and its continuing existence can choke the root system of our lawn throughout the year. Wintergrass must be treated when it’s young, and the very best time to treat it is pre-emergent. That means knowing that Wintergrass will soon emerge and killing it before it is even seen. Wintergrass can be treated pre-emergent from May.
Fertilise Correctly
This means having a plan for fertilising at the right times with the right fertilisers. Put down a high quality Winter Fertiliser in May prior to Winter arriving. The next application of Winter fertiliser should be in July, 8 weeks later. Apply to manufacturers recommendations. Winter fertilisers contain higher levels of Iron which is essential for good lawn health through Winter.
Kill Winter Weeds
Generally broadleaf weeds will become more prominent in Winter as conditions for their survival improve, and as the ability for the lawn to fight against them decreases, best to treat them as early as possible before they spread.
Pruning
Overgrown trees and bushes may increase their shade levels in Winter, and by the time we notice that our lawn has started dying in affected areas, it can be too late to repair the damage. So it’s best to plan ahead and prune trees and other bushes in Autumn.
