During winter months, it is better to leave your lawn a bit longer than usual. Longer grass blades provide more protection against extreme cold temperatures and can help the turf avoid injuries like desiccation (drying out) or crown hydration (freezing). Additionally, long grass helps preserve moisture in the soil beneath and prevents weeds from germinating. Finally, leaving your lawn at a higher length cuts down on mowing frequency which will save you time and money over the course of winter.
