How Long Does Bermuda Dormancy Last in DFW and When Does Spring Green-Up Start

By late January, Arlington and DFW homeowners are staring at the same brown, straw-colored yards they’ve been looking at since November. The question on everyone’s mind is the same: how much longer? When does this thing turn green again? The honest answer is that it depends — but not randomly. Bermuda green-up in North Texas follows predictable patterns driven by specific temperature triggers, and understanding those patterns means you can stop guessing and start planning. Here’s the real science behind dormancy duration and what to expect week by week as spring approaches.

How Long Does Bermuda Dormancy Typically Last in DFW?

In the Dallas–Fort Worth area, Bermuda grass is usually dormant from mid-to-late November through late March, give or take several weeks depending on the year. That’s roughly a four-to-five-month window of brown turf. Some years with mild winters, partial green-up can persist into December or resume in late February. Years with late cold snaps — like 2021 — can push the dormant period into April. The range is real, and it’s entirely weather-driven.

The most important thing to understand is that calendar date doesn’t trigger green-up — soil temperature does. Bermuda begins the transition out of dormancy when soil temperatures at the 2-inch depth consistently reach and hold above 65–70°F. Until that threshold is crossed and maintained, the crown won’t push new growth regardless of how warm the air feels or how sunny the days are.

Why Soil Temperature Is the Only Metric That Matters

Bermuda is a C4 grass with metabolic machinery optimized for high-temperature conditions. The enzymes involved in carbohydrate transport and cell division simply don’t function efficiently below 60°F. Even if you have a string of 70-degree days in late February, if soil temps are still sitting at 55°F — which is common after a cold winter — your Bermuda will stay dormant. The grass isn’t being stubborn; it’s responding correctly to what’s happening in the root zone.

Soil temperatures in DFW tend to lag air temperatures by two to four weeks in spring. A warm April week can push soil temps up quickly, but they also drop back down fast if another cold front rolls through. Sustained warmth — not just a few nice days — is what triggers and maintains green-up.

Week-by-Week Green-Up Timeline for North Texas

Here’s what a typical green-up progression looks like in the Arlington area during an average year:

• Late February: No visible change. Soil temps are likely still below 55°F. Don’t fertilize; don’t scalp; don’t make any decisions based on what the lawn looks like right now.
• Early March: Soil temps may be approaching 60°F on warm days. Still no green-up, but the pre-emergent application window has opened. This is the ideal time to apply spring pre-emergent for crabgrass and warm-season annual weeds.
• Mid-March: In average years, the first hints of green begin appearing in the warmest, most sun-exposed parts of the lawn. South-facing slopes and areas near driveways or pavement warm first.
• Late March: Green-up accelerates noticeably. Many lawns are showing 30–50% green coverage. This is scalping season — once you see consistent new green pushing through, it’s time to cut low and bag the dead canopy.
• April: Bermuda transitions to full green in most DFW yards. Growth rate picks up dramatically. Mowing frequency increases from biweekly to weekly. First fertilizer application of the year goes down once the lawn is 50%+ green.
• Early May: Full green canopy established. The lawn is actively growing, competing with weeds, and beginning to fill in any thin areas.

What Speeds Up or Slows Down Green-Up

Not all yards green up at the same pace, even in the same neighborhood. Several factors push the process faster or slower:

• Sun exposure: Full-sun lawns consistently green up two to three weeks earlier than shaded lawns. The shade keeps soil temps cooler longer.
• Soil type: Sandy or amended soils warm faster than DFW’s dense clay. If you’ve been aerating and topdressing over the years, your soil warms faster.
• Pavement proximity: Concrete driveways and sidewalks store heat and radiate it back into adjacent turf. Bermuda near pavement reliably shows the first green of the season.
• Lawn health going into dormancy: A lawn that entered winter with healthy crowns, no disease pressure, and good nutrition stores green up faster and more uniformly than a stressed lawn.
• Late freezes: A late March or early April cold front can temporarily halt green-up that had already started. This rarely causes permanent damage, but it can set the visible green-up back by one to two weeks.

Common Mistakes Made During the Green-Up Wait

The weeks between dormancy and full green-up are when most lawn care mistakes happen, because homeowners are impatient and the lawn looks bad. The most common errors:

• Scalping too early. Scalping before green growth is actively pushing stresses the crown and removes insulation it may still need for late cold snaps.
• Fertilizing before 50% green-up. Nitrogen applied to a lawn that isn’t actively growing feeds soil microbes and weeds, not turf. Wait for clear green activity.
• Declaring areas dead in March. Brown patches in March are almost always dormant, not dead. Give them until May before drawing any conclusions.
• Watering heavily. Dormant and early green-up Bermuda needs minimal irrigation. Saturating cold soil slows warming and can promote crown disease.

How Hamann Times Your Spring Program

Our lawn care program for DFW is built around soil temperature triggers, not calendar dates. We monitor conditions and time pre-emergent, scalp recommendations, and first fertilizer applications based on what’s actually happening in the soil — not what the calendar says. That’s how you get a lawn that greens up fast, stays clean of weeds, and carries momentum through the whole growing season. Hamann has been doing this in Arlington and across DFW since 2006.
