Yellow Bermuda Grass: How to Find the Real Cause
Yellow Bermuda grass isn't a diagnosis. It's a symptom, and the important part is figuring out what caused it before you start treating it. When Bermuda turns yellow, I like to work through the simple possibilities first: water, insects, disease, nutrients, mowing or chemical damage, and a few weird environmental problems that are surprisingly easy to miss. The shape of the yellow area, what the individual grass blades look like, what's happening below the soil, and when the problem appeared can usually narrow things down pretty quickly. The goal isn't to become a turf pathologist every time your lawn changes color. It's to slow down long enough to collect a few clues. In this guide, I'll walk through a simple diagnostic process you can use before you start buying products or applying treatments.

How to Measure Your Lawn for Fertilizer and Watering
Knowing your lawn's square footage is one of those basic measurements that makes almost everything else easier. Fertilizer rates are commonly expressed per 1,000 square feet, product bags list coverage in square feet, and knowing the size of individual lawn sections helps you stop guessing about how much product you're actually applying. You can measure a simple lawn with a tape measure, break an irregular lawn into smaller shapes, or use satellite imagery from Google Maps or Google Earth to trace the turf from above. Then, when it comes to irrigation, pair that lawn map with a catch-can test to find out how much water your sprinklers are actually delivering. Once those numbers are known, fertilizer and watering become much more repeatable.
How to Control Spurge in Bermuda Grass
Spurge can go from a few little plants in Bermuda grass to a frustrating summer infestation surprisingly fast. The problem isn't just killing the plant—it's stopping the next generation. Spotted and prostrate spurges grow low enough to survive mowing, develop a taproot, and can begin producing seed only weeks after germination. Those tiny seeds can also move around on shoes, equipment, and mower tires. My approach is to think about spurge control in layers: pull isolated plants before they seed, selectively treat larger infestations with a herbicide labeled for Bermuda grass and spurge, use pre-emergent herbicides to reduce future germination, and keep the Bermuda dense enough to leave fewer openings for spurge in the first place. The goal isn't just to make today's weeds disappear. It's to keep today's spurge from becoming next summer's problem.
How to Use a PGR on Bermuda Grass: An Advanced Technique
Plant growth regulator is one of my favorite advanced tools for maintaining a low-cut Bermuda lawn. A trinexapac-ethyl PGR doesn't simply stop the grass from growing—it suppresses vertical growth, which can reduce mowing and help produce that tight, dense appearance we're chasing. But this isn't a product I'd grab, eyeball into a sprayer, and start experimenting with. Your exact Bermuda cultivar matters. Application rate matters. Spray coverage matters. Temperature matters. And once you begin making repeat applications, the interval between them matters a lot. I like starting conservatively, applying PGR as a foliar spray with plenty of carrier water, and pairing it with light nitrogen and iron. Then I track growing degree days instead of blindly spraying every couple of weeks. Get it dialed in and PGR can completely change how you maintain Bermuda. Get too aggressive, and you can bring growth almost to a halt.
Should You Aerate Bermuda Grass?
Core aeration can be one of the most useful things you do for a compacted Bermuda lawn, but I don't look at it as something that automatically belongs on the calendar every year. I want a reason to punch thousands of holes in otherwise healthy turf. For me, that usually means I'm dealing with suspected compaction or I'm already planning to topdress and want to work material deeper into the rootzone. Just as important is timing. I aerate when my Bermuda is actively growing and capable of repairing the damage quickly—not heading into fall dormancy. I also like the soil moist enough for good tine penetration without being so wet that the aerator, my footsteps, and eventually my mower create another compaction problem. Here's how I decide whether aeration is worth doing and how I fit it into the rest of my lawn work.
How to Revive Bermuda Grass After Drought or Heat Stress
Bermuda grass can look absolutely cooked after a stretch of extreme heat and drought, but brown turf doesn't necessarily mean dead turf. Bermuda is remarkably heat- and drought-tolerant, spreads through stolons and rhizomes, and can recover aggressively once favorable growing conditions return. The trick is giving the surviving grass what it needs to start moving again. My approach to severe summer stress is pretty straightforward: restore moisture first, remove enough dead material to give surviving Bermuda room and light, correct compaction when necessary, then use fertilizer to support growth once the turf is hydrated and actively responding. On my lawn, I've watched ugly, seemingly bare areas produce noticeable green growth within about a week and dramatically improve in roughly 12 days, with stubborn spots filling over the following weeks. The key is understanding that water starts the recovery, but active Bermuda still has to reclaim the lawn.
How to Identify and Control Goosegrass in Bermuda Grass
Goosegrass is one of those weeds that's much easier to deal with once you know exactly what you're looking at. Its flattened, whitish center and low, wagon-wheel growth habit make mature plants fairly distinctive in Bermuda. My approach isn't just to find the strongest herbicide I can spray. I want to prevent new plants, physically remove isolated goosegrass when that makes sense, selectively treat what remains when conditions are right, and keep the Bermuda growing aggressively enough to reclaim the space. Summer heat complicates chemical control, so I personally don't like spraying when we're living in the 90s and the turf is already stressed. Sometimes the best weed killer in July is a Grandpa's weeder, a bucket, and healthy Bermuda ready to fill the hole.
How to Fix Bare Spots in Bermuda Grass
Bare spots in a Bermuda lawn don't automatically mean you need seed or new sod. Bermuda has one major advantage when it comes to lawn repair: it spreads aggressively through above-ground stolons and below-ground rhizomes. Once you've corrected whatever caused the damage—whether that's insects, disease, drought, traffic, or another problem—healthy Bermuda around the spot can often grow back into it. The goal is to help that natural recovery process along. Make sure the lawn has adequate nitrogen, keep the repair area supplied with water, and consider moving plugs from healthy turf into larger bare areas. Plugging effectively shortens the distance the Bermuda has to travel. Just make sure you know whether you have seeded common Bermuda or a vegetatively propagated hybrid before reaching for a bag of seed.
