What is Winterizing a Lawn?

Semi-Dormant - Green but not Growing

Cool air and soil temperatures suspend normal turf growth – a type of hibernation until warmer temperatures arrive in the spring. However, not everything is on hold until the next warm spring day. Some weeds and fungi can thrive in cooler temperatures. Winterizing your lawn is necessary to take care of the fungus and weeds that can attack your lawn during the winter months. I use granular fertilizers high in Potassium and strong liquid herbicides to “Winterize” your lawn.

Potash to the Rescue

Potash is rich in Potassium and it strengthens your lawn against fungus attacks. It does more than just prevent fungus; it strengthens cells and helps with food absorption. The potash is best applied as a granular and broadcasting into planted beds and non-turf areas helping to prevent diseases from spreading from untreated areas.

Dormant Turf and Green Weeds – Easy Weed Control

With the dormant turf not being sensitive to herbicides and the winter weeds hypersensitive, weed control is a lot easier than in the hot summer months. However, the downside is I can only treat weeds that are present – weeds that germinate after I leave will have to wait until I return. The best solution is a monthly weed application available with the Premium Service – a monthly lawn spraying upgrade.

Investing in the Future

Winterizing your lawn does little for your lawn today but will pay big dividends in the Spring with a greener, healthier and weed-free lawn.
