As fall comes to a close and temperatures drop, prepping your lawn for winter becomes essential. One of the most overlooked steps? Mowing. Cutting your grass to the right height before winter can make the difference between a lawn that bounces back in spring — and one that’s patchy, thin, or full of weeds.
Let’s break down how short to cut grass before winter, why it matters, and what to avoid.
What’s the Best Time to Mow in Late Fall?
The best time to perform your final mow is when your grass has nearly stopped growing, typically when daytime highs consistently fall below 50–55°F. For warm-season grasses like Bermuda or Zoysia, this could be late October or early November. For cool-season grasses like fescue or ryegrass, it may be mid to late November.
You want to give your lawn one last cut before it goes fully dormant — but not so early that it continues growing and becomes overgrown by winter.
Not sure when your grass is ready for its final mow? WP Law can help you assess your lawn’s condition and recommend a schedule based on your specific grass type and region.
Signs You’re Cutting Too Short
It’s tempting to go lower on your last mow, but cutting more than one-third of the blade height can cause shock. Common signs you’ve gone too short include:
- Browning or yellowing tips
- Patchy or uneven growth
- Slower regrowth in spring
- Increased weed invasion or bare spots
As a rule of thumb:
- Cool-season grass: Final mow height should be 2.5–3 inches
- Warm-season grass: Final mow height should be 1.5–2 inches
These heights protect the grass crown while preventing matting or moisture buildup over winter.
Does Mowing Frequency Change in Fall?
Yes — grass growth slows down as days get shorter and temperatures drop. While you may mow weekly in summer, fall mowing typically drops to every 10–14 days. Pay attention to growth, not the calendar. The goal is to avoid scalping the lawn or letting it grow too tall before winter.
You’ll also want to keep mower blades sharp and avoid mowing when the grass is wet or frosty, which can damage the turf and compact the soil.
