Bermuda Grass Lawn Care in Las Cruces

Bermuda is the lawn grass most Las Cruces homes have, and for good reason: it loves heat, handles foot traffic and recovers fast. It also goes brown every winter, spreads into beds and turns yellow in our alkaline soil if you don’t manage it. Here’s a simple year-round plan.

Quick answer

How do you take care of Bermuda grass in Las Cruces?

Mow Bermuda at about 1 to 1.5 inches without cutting more than a third of the blade, water deeply on your three City days for about 1 inch a week in summer, fertilize lightly each month from May through September, and let it go dormant in winter.

Most Bermuda problems in Las Cruces come from mowing too high or too rarely, shallow daily watering, and yellowing from iron-poor alkaline soil. All three are easy to fix.

Mowing

How short should you mow Bermuda grass in Las Cruces?

NMSU Extension recommends 0.5 to 1.5 inches for residential Bermuda lawns. Common Bermuda does best near 1 to 1.5 inches, while hybrid varieties can go lower. Mow often enough that you never remove more than a third of the blade, usually every five to seven days in summer.

Follow the one-third rule

Never cut off more than about a third of the grass at once. If you mow at 1 inch, mow again when it reaches about 1.5 inches. In peak summer that can mean every 5 to 7 days.

Leave the clippings

Mowing often enough means clippings can stay on the lawn. NMSU notes they return nutrients and can cut fertilizer use by about 25 percent.

Keep blades sharp

Dull blades tear the grass and leave a whitish cast. Sharpen at least once a year, in spring.

Raise the height a little during extreme heat or drought stress, and before winter dormancy. Source: NMSU Extension Guide H-505, Mowing Your Lawn.

Watering

How should you water Bermuda on the Las Cruces schedule?

Water Bermuda deeply on your three City watering days, early in the morning, aiming for about 1 inch a week in summer, or roughly a third of an inch per watering day. Use short cycles to stop runoff, and skip daily light watering that keeps roots shallow.

Season	What to aim for	Notes
Late spring (May to June)	About 1 in per week, split over your 3 days	Growth takes off; watch for dry spots
Summer (July to September)	About 1 to 1.25 in per week	Monsoon rain counts; skip after a good storm
Fall (October)	Taper down	Lawn slows before dormancy
Winter (November to March)	Light, occasional watering	Dormant grass still needs some moisture

Water before 10 a.m. on your assigned days (even addresses Tue/Thu/Sat, odd addresses Wed/Fri/Sun, no watering Monday). Split each day into two or three short cycles on hard or sloped ground so water soaks in instead of running off. See our watering schedule guide and sprinkler run-time guide.

Feeding

What is the best fertilizing schedule for Bermuda in Las Cruces?

A good Las Cruces yard fertilizing schedule for Bermuda is about half a pound of nitrogen per 1,000 square feet each month while it actively grows, roughly May through September. Ammonium sulfate at about 2-1/2 pounds per 1,000 square feet delivers that. Follow the label.

University of Arizona Extension recommends about 1/2 pound of nitrogen per 1,000 square feet each month while Bermuda is actively growing. In the low desert that’s April through October; in Las Cruces, which is higher and cooler, active growth usually runs from about May through September.

For example, ammonium sulfate (21-0-0) at about 2-1/2 pounds per 1,000 square feet delivers that amount. Always follow the product label, and water it in.

Don’t feed a dormant lawn. Wait until it’s at least half green in spring.
Stop feeding by early fall so it can harden off before frost.
Yellow but growing? Our alkaline soil often locks up iron. An iron product usually greens it up faster than more nitrogen.

Sample Bermuda calendar

Month	Task
Feb	Pre-emergent for goatheads and weeds
Mar to Apr	Sharpen blades, check sprinklers, scalp lightly
May	First feeding once half green
Jun to Aug	Monthly feeding, dethatch or aerate
Sep	Last feeding
Oct	Raise mowing height, taper water
Nov to Feb	Dormant; light water, keep leaves off

Common problems

How do you fix common Bermuda lawn problems?

Winter browning is normal dormancy. Yellow summer blades usually mean iron deficiency in alkaline soil, dry brown patches point to sprinkler coverage gaps, a spongy lawn needs dethatching from June to August, and goatheads call for late-winter pre-emergent and thicker turf.

Problem	Likely cause	Fix
Brown lawn in winter	Normal dormancy	Nothing; it greens up in spring
Yellow blades in summer	Iron deficiency in alkaline soil	Iron supplement; avoid overwatering
Dry brown patches	Sprinkler coverage gaps or broken heads	Check heads and spacing
Spongy lawn, water runs off	Thatch over 3/4 inch	Dethatch or aerate June to August
Goatheads and weeds	No pre-emergent, thin turf	Late-winter pre-emergent, thicker turf
Grass creeping into beds	Bermuda spreads by runners	Deep edging and regular trimming

Winter

Should you overseed with winter ryegrass?

You can overseed Bermuda with annual ryegrass in fall to keep a green lawn through winter, but it means more water and mowing in months when Bermuda would rest. Many Las Cruces homeowners let Bermuda go dormant or shrink the lawn and convert the rest to xeriscape.

If you’d rather have green year-round without watering or mowing, artificial turf is the other option.

Bermuda grass FAQs

NMSU Extension recommends 0.5 to 1.5 inches for residential Bermuda lawns. Most common Bermuda looks best around 1 to 1.5 inches. Mow often enough that you never remove more than a third of the blade.

About 1 inch a week in late spring and 1 to 1.25 inches in the hottest months, applied deeply on your three City watering days before 10 a.m. Less in fall, and only light watering in winter.

Once the lawn is at least half green in spring, usually May in Las Cruces, and monthly through about September. University of Arizona Extension recommends about 1/2 pound of nitrogen per 1,000 square feet per month during active growth.

In Las Cruces the most common cause is iron deficiency from alkaline soil, especially in heavy or overwatered spots. An iron supplement usually fixes it. Also check for overwatering and poor drainage.

Bermuda is a warm-season grass and goes dormant when temperatures drop, usually from about November to March here. It isn’t dead, and it greens up again in spring.

During active summer growth. University of Arizona Extension names June through August as the ideal time.

Use deep edging, trim runners regularly, and keep a clear border between lawn and beds. Rock beds over weed barrier with steel edging hold the line best.

Only if you want a green lawn all winter and don’t mind the extra water and mowing. Most homeowners let Bermuda go dormant.
