Spring Lawn Care Checklist for Keller and Fort Worth Homeowners
Buffalo Outdoor • April 2026 • Fort Worth, TX
Spring is the most important season for Bermuda grass lawns in the Keller and Fort Worth area. Apply pre-emergent before soil temperatures hit 55°F, wait for 50% green-up before fertilizing, hold off on irrigation until temperatures are consistently warm, and schedule pest control before fire ants and mosquitoes establish. Here is the complete breakdown with timing specific to our area.
Why Spring Defines Your Entire Lawn Season
If you are a homeowner in Keller, Fort Worth, or anywhere in Tarrant County, spring is the season that determines how your lawn performs for the rest of the year. The decisions you make between March and May set the foundation for everything that follows. Get them right and your Bermuda comes in thick, green, and resilient enough to handle the North Texas summer. Miss the windows and you spend June through September trying to catch up.
Here is what we recommend based on years of caring for lawns across Keller, Fort Worth, Aledo, Saginaw, Southlake, and the surrounding communities.
Early Spring (Late February to Mid-March): Pre-Emergent and Cleanup
Pre-Emergent Herbicide
Pre-emergent herbicide is the single most important spring treatment. It creates a barrier in the soil that prevents crabgrass, goosegrass, and other summer annual weeds from germinating. In the Fort Worth area, soil temperatures typically reach the critical 55-degree threshold in early to mid-March. The application must go down before germination begins — once crabgrass seeds sprout, pre-emergent cannot stop them.
General Property Cleanup
Remove any debris, fallen branches, and leftover leaves from winter. If your lawn has significant thatch buildup, a light scalp — lowering the mower about half an inch below your normal height — can help remove dead material and let sunlight reach the green growth underneath. Do not cut Bermuda to the ground, as that removes stored energy and stresses the plant right when it is trying to wake up.
Mid-Spring (Late March to April): First Fertilizer and Weed Control
First Fertilizer Application
Wait for your Bermuda to reach at least 50 percent green-up before applying the first fertilizer of the season — typically late March or early April. A slow-release nitrogen fertilizer is the right choice. It provides steady nutrition over several weeks rather than a quick surge that pushes rapid top growth at the expense of root development. The goal in spring is to support strong, healthy root growth that will sustain the lawn through summer heat.
Broadleaf Weed Control
Mid-spring is when broadleaf weeds like dandelions, clover, and henbit are most vulnerable to post-emergent treatment. They are actively growing, relatively small, and responsive to herbicide. The same weeds become much harder to control once they mature and set seed. A targeted broadleaf application in April catches them at their weakest.
Late Spring (May): Mowing, Watering, and Pest Prevention
Mowing Best Practices
By May, your Bermuda should be fully green and growing aggressively. Mow weekly at 1.5 to 2 inches and never remove more than one-third of the blade in a single session. Keep your mower blades sharp — dull blades tear grass rather than cutting it cleanly, creating entry points for disease.
Smart Watering Strategy
Hold off on supplemental irrigation until temperatures are consistently above 85 degrees and rainfall becomes unreliable. When you do start, go deep and infrequent: about 1 inch per week applied in one or two longer sessions. This trains roots to grow deep, building a lawn that handles heat stress without constant intervention.
Early Pest Prevention
Late spring is the time to get ahead of pest pressure. Fire ants are establishing new mounds, mosquitoes are breeding, and fleas and ticks are becoming active. A perimeter pest treatment in May creates a barrier that reduces pest populations before they reach peak levels in summer.
Spring Irrigation System Check
If your property has an irrigation system, spring is the time for a tuneup. Over the winter, heads can shift, lines can develop leaks, and nozzles can become clogged. A spring irrigation check ensures that every zone is delivering water evenly and efficiently before you start relying on the system during the hot months.
Uneven irrigation is one of the most common causes of patchy, inconsistent lawns in the Fort Worth area. One zone overwatering creates fungal disease conditions. Another zone underwatering creates dry, stressed turf. A properly calibrated system prevents both problems and can significantly reduce your water bill over the course of the season.
Disease Watch: Know What to Look For
Fort Worth area Bermuda lawns are susceptible to several spring diseases, and catching them early makes treatment far more effective. If you notice any areas of your lawn that look off — patches that are yellowing, thinning, or not greening up with the rest of the yard — it is worth having a professional evaluate the situation.
Brown Patch
Can appear when nighttime temperatures are still cool and humidity is high.
Take-All Root Rot
Shows up as yellowing patches that do not respond to fertilizer applications.
Large Patch
Creates circular areas of thinning, discolored turf that spread throughout the season if untreated.
Disease that goes undiagnosed and untreated in spring can spread throughout the summer and cause damage that takes a full season or more to recover from.
