When Is the Best Time to Fertilize Your Lawn in Dallas?
Fertilizer. Not exactly the flashiest part of lawn care, but if you want that thick, green grass in Dallas? It’s a must.
Still, tossing down fertilizer whenever you remember isn’t the move. Timing matters—especially in Texas, where your grass deals with heat, heavy clay soil, and a weather forecast that can’t make up its mind.
Let’s break down when to fertilize your lawn, what kind to use, and why getting the schedule right can be the difference between a patchy lawn and a front yard you’re proud of.
Why Timing Matters More Than You Think
You can buy the best fertilizer money can buy—but apply it in the wrong season, and you’re wasting your time (and probably burning your lawn). Dallas lawns mostly use warm-season grasses like Bermuda, Zoysia, and St. Augustine. These grasses don’t like cold feet, and they don’t like being overfed in the summer, either.
That’s why fertilizing isn’t a “whenever you feel like it” task. It’s more like a seasonal tune-up.
The Best Time to Fertilize in Dallas, TX
Early Spring (March – April): Wake-Up Call
This is when your grass starts to stretch after its winter nap. It’s not time for a full meal—just a gentle nudge.
Use a balanced, slow-release fertilizer (15-5-10 is a good pick).
Avoid high nitrogen products here—you’re growing roots, not racing to mow.
Pair it with pre-emergent weed control to block crabgrass and other early risers.
If you’re unsure which products are right for your lawn or want help getting started, our lawn care services include everything from fertilization to weed prevention.
Late Spring to Early Summer (May – June): Full Feed
By now, your lawn is actively growing—and hungry. This is when you give it the good stuff.
Apply a nitrogen-rich fertilizer to boost blade growth and color.
Water it in well. Morning is best.
Mow regularly to prevent stress and keep things tidy. (Need help? We mow too.)
This is the time your lawn hits its stride. If you’ve been feeding and mowing properly, this is when people start to say, “Hey, what are you doing to your grass?”
Mid to Late Summer (July – August): Easy Does It
When the heat kicks in, hold off on heavy fertilizer. Your lawn is already stressed from the sun.
If you fertilize at all, use a slow-release or organic blend in low doses.
Over-fertilizing in the heat can burn your lawn.
Focus more on irrigation and mowing high. Keep those roots shaded.
And if your grass is struggling, it might not be your fault—it could be your soil. We offer drainage solutions if water isn’t soaking in like it should.
Fall (September – October): Prep for Winter
This is one of the most important steps of the year—don’t skip it.
Apply a fertilizer that’s high in potassium to strengthen the roots.
This helps your lawn survive the winter and green up faster next spring.
Fall is also a great time to overseed or repair damaged areas.

What About Winter?
In Dallas, grass goes dormant in winter. Between November and February, you’re off the hook—no fertilizer needed. Just keep your yard clear of leaves and debris so mold and pests don’t move in while your lawn’s asleep.
