Your Bermuda Is Already Telling You
If you've noticed you're mowing less often lately, that's not your imagination. Bermuda is a warm-season grass, and once our nights start dropping into the 50s in October, it slows down hard. A lawn that needed cutting every five or six days in July might go a week and a half or more between mows by late October.
The real stopping point is the first hard frost. Once temperatures dip below freezing long enough to burn the leaf blades, bermuda goes dormant and turns that familiar tan-brown. In Kay County, that usually lands somewhere between late October and mid-November, though some years it comes earlier or later.
After that, there's no growth to cut. Your last mow of the year is the one right around that first hard freeze, and how you handle it matters more than most people think.
How Tall to Leave It for Winter
Leave bermuda at its normal mowing height for the last cut, or even a touch higher. Don't drop the deck to get one more "clean" look before winter. Most home bermuda lawns around Ponca City do well kept in the range of roughly an inch and a half to two inches, and the final cut should sit at the upper end of whatever height your lawn is used to.
That leftover leaf and stem does real work over the winter. It shades and insulates the stolons and crowns near the soil surface, which is where next spring's green-up comes from. A North Oklahoma winter can swing from 70 degrees to single digits in a couple of days, and that extra cover helps buffer the grass through those swings.
If you have fescue, the rules are different. Fescue is a cool-season grass and keeps growing through fall, so you may be mowing it into December. Keep it tall, around three inches or a bit more. Zoysia behaves much like bermuda and should go into winter at its usual height, not shorter.
Why Fall Is the Wrong Time to Scalp
Scalping, cutting bermuda down close to the soil and removing the dead material, is a legitimate practice. But it belongs in spring, once the threat of hard freezes has passed and the grass is ready to green up. Done in fall, it works against you.
Here's what goes wrong when you scalp going into winter:
- It strips away the insulating layer that protects the crowns and stolons from cold snaps and drying winter wind.
- It exposes bare soil, which dries out faster and freezes harder.
- It opens up the canopy for winter annual weeds like henbit and chickweed, which germinate in fall and love thin, short turf.
- It gives the grass no chance to recover, since dormant bermuda can't regrow to fill in the damage until spring.
What the Last Visit of the Season Should Include
The final mow is a good time to set the property up so it looks tidy through winter and comes back strong in spring. A good last visit covers more than just the grass.
On the lawn itself, the goal is a clean, even cut at normal height with sharp blades. A dull blade tears the leaf tips and leaves a ragged, frayed look that's especially obvious once the lawn browns out.
- Mow at the usual height with a sharp blade, not lower.
- Edge driveways, sidewalks and curbs one last time so the lines stay crisp all winter.
- Trim around fences, trees, mailboxes and beds so there aren't shaggy tufts sticking up.
- Get leaves off the lawn. A heavy mat left sitting all winter holds moisture against the grass and blocks light when spring green-up starts.
- Clean out landscape beds, pull spent annuals, and cut back perennials that won't hold up through winter.
- Blow off hard surfaces and clear clippings and debris out of beds and gutters near the ground.
- Walk the yard and note thin spots, low areas that hold water, or damage you want to address in spring.
A Word on Weeds You'll Start Seeing
Once bermuda goes dormant, anything green in the lawn stands out. Those are usually winter annual weeds that sprouted in the fall and will flower in late winter and early spring. They show up most in thin or scalped areas, which is another reason to leave the grass at a healthy height.
Mowing won't solve a weed problem, and Boss Mowing doesn't do any chemical treatment. If winter weeds are a recurring issue in your yard, talk with a licensed applicator. Timing matters a lot with weed control here, so it's worth calling one in fall or late winter rather than waiting until spring when the weeds are already blooming.
Before You Put the Mower Away
If you mow your own lawn, a little care now saves trouble in March. Clean grass buildup off the underside of the deck, sharpen or replace the blade, and follow your owner's manual on fuel storage so the mower starts when you need it.
Even with the grass dormant, plan to keep leaves picked up through December, since our oaks and other late-dropping trees keep shedding after the first freeze. A dormant lawn doesn't need mowing, but it still benefits from being kept clear.
If you'd rather have the last mow and cleanup handled for you, Boss Mowing does fall cleanups across Ponca City, Blackwell, Tonkawa, Newkirk and the surrounding area, starting at $250. That covers the final cut, edging, trimming, leaf removal and bed cleanup so your yard is ready for winter.
