Although growth is slow, it’s important to give your lawn some TLC even in the cold winter months. We’ve put together a simple and effective winter lawn care guide. It has several tips and a recommended nutrient schedule using UltraGrow products. The products focus on keeping your lawn healthy, strong, and ready to bounce back in spring.
Nutrients During Winter
Every 1 – 2 weeks: Dyna-Maxx Pure Seaweed
It will boost root strength, improve stress resistance, and support soil microbiology — especially important during winter slow-down. It is great for all lawns especially those stressed by shade or light ware.
Monthly: Power-Maxx Garden (NPK 12-2-7)
This will give a gentle boost without over stimulation. It helps to bridge the gap between ‘doing nothing’ and over feeding during winter.
Start & End of Winter: Microbial Force & Iron Life
Microbial Force is a living soil booster and it will introduce and feed beneficial soil microbes that keep your lawn’s ecosystem active, even in cooler weather.
Iron Life will give an instant green colour to your lawn, giving it a lush look.
Winter Lawn Care Tips
Sunlight
During winter, your lawn needs as much sunlight as possible, so make sure you keep on top of your garden chores and remove all the deciduous tree leaf droppings and make sure you use your catcher when mowing to avoid grass clipping build up.
Mowing Height
When it’s cold, grass and plants grow much slower (when was the last time you mowed?). For this reason, try raising the height of your mower to protect your soil and grass and trap the heat. This will also help to maximise photosynthesis.
Weed Treatment
It is also a perfect time to be taking care of those pesky winter weeds. Get control of them before the warm weather, as once spring hits they’ll go crazy! All-purpose weed killers containing Bromoxynil for Buffalo lawns and Bentazone and Dicamba for couch lawns.
Buffalo varieties such as Sir Walter DNA Certified require specialty herbicides. Most standard herbicides, suitable for couch lawns will damage a buffalo. So make sure you check the active constituents closely and use the right product!
