The winter weather might mean you want to be curled up inside but looking after your lawn through rain and the cooler months can prevent disease, and ensure your lawn is looking great for spring time.

Protect from Disease

How to Prevent Lawn Diseases in Winter

If you’re noticing small discoloured, brown/pink or even dead patches of grass, it’s time to act now as these can be signs of a lawn disease known as winter fusarium or fusarium patch (Microdochium nivale). It’s common in lawns that are well watered, have a thick layer of thatch, and have soils high in nitrogen. The fungus develops when night temperatures are low and can be exacerbated when there is water sitting on leaf blades.

To help prevent disease, the best method is to manage plant health and nutrition. A healthy lawn is less likely to be susceptible to disease. Avoid using lawn fertilisers high in nitrogen, especially in autumn, and instead, focus on applying a complete fertiliser, like Yates Dynamic Lifter Organic Lawn Food for nourishment.

Thatch can be a breeding ground for spores, so lawn care that reduces thatch build-up such as renovations in spring or simply mowing with a catcher can reduce disease incidence.

During winter, lawns aren’t regularly watered so when rainfall does occur, it can be met with hydrophobic soils that result in water sitting on the surface. Using a soil wetting agent such as Yates WaterWise Soil Wetter Concentrated will improve water penetration and benefit the health of the lawn.

Best Treatment for Common Lawn Diseases

If you notice the diseases Brown Patch, Dollar Spot, Fusarium, and Helminthosporium creeping in during winter, treat with Yates Mancozeb Plus Garden Fungicide & Miticide.

How to Control Weeds in Your Lawn in Winter

Australia’s weeds are mostly made up of winter annuals, this means they germinate in autumn and grow through winter. Treating them once they have all sprouted is the easiest, thus making winter the perfect time to do so. Yates’ range of Lawn Weed Control products can help prevent broadleaf weeds such as bindii, clover, dandelion and capeweed, and comes in both granular, ready to use spray and hose-on applications to suit your lifestyle.



How to Water Your Lawn in Winter

Over-watering your lawn during the winter months can encourage disease. Unless it looks very dry and leaves are curling, it’s a good idea to significantly reduce the watering of your lawn during the cooler months. If you do need to water, do it in the mornings so the lawn has time to dry off during the day rather than staying damp all night.

How to Protect Your Lawn from Frost

Frost is the water in your grass blades freezing, so walking over it results in these grass blades snapping under your feet. So, keep off the grass! This damage will be seen initially as black marks and later as brown dead leaf. When you have a light frost, it is possible to help the plant by applying a light application of water before the sun rises; this can remove the frost quicker and help the plant deal with the shock/stress of the temperature. If the frost is heavy, or the morning is still cold, do not apply more water as this can just add water that gets frozen, significantly increasing the problem.



Why You Don't Need to Mow Your Lawn in Winter

Stop mowing your lawn during winter to keep some extra length on your turf. This allows extra leaf area for photosynthesis, keeping your lawn healthier and greener.

How to Get Your Lawn Mower Ready for Spring

If you’re looking for things to do in the garden during a quieter time, now’s the time to make sure your lawnmower is ready for spring. Sharpen the blades so it’s ready for the first cut of the year, and can cut grass cleanly and evenly. 


How & When to Feed Your Lawn in Winter

Many grasses lie dormant over winter, so there is no need to feed for the most part of the season. For you to get the best from your fertiliser, the lawn needs to be waking up. Late August or early September is the perfect time to feed your lawn. This ensures there are enough readily available nutrients in the soil to help it start growing well when spring arrives. Yates Dynamic Lifter Concentrated Lawn Food is a complete lawn fertiliser that provides both fast acting nutrients and slow release organics. Double the strength of our Yates Dynamic Lifter Organic Lawn Food, it has added potassium to promote strong healthy lawns, preparing them for the upcoming lawn activities and the stressful summer heat.
