No — for the vast majority of North Texas homeowners, once a week is the right call. Cutting more frequently than your lawn actually needs stresses the grass, wastes your time and money, and doesn't produce a healthier lawn. Here's what actually matters when it comes to mowing frequency.
The One-Third Rule Is What Drives Everything
The reason once a week works comes down to one principle: never remove more than one-third of the grass blade in a single cut. Cut too much at once and the grass diverts energy from root growth to blade recovery — in a Texas summer, that's how you get a patchy, stressed lawn.
When you mow consistently every week, you stay well within that range. You're taking a little off the top, not scalping it. That consistency is what keeps North Texas lawns healthy through brutal summers. It's also exactly how we approach every lawn we service at JHernandez Lawn Service — same day, same height, every week.
Bermuda vs. St. Augustine — Same Answer, Different Reasons
The two grass types we see most across DFW both thrive on a weekly schedule.
Bermuda is a fast grower, but at the right mow height (1.5"–2.5"), weekly cuts keep it tight, dense, and healthy. It handles the heat well when it's not being over-stressed by unnecessary mowing.
St. Augustine actually prefers being left alone a little longer between cuts, with an ideal height of 3"–4". Weekly mowing at the right height is perfect — any more frequent and you risk weakening the blades and inviting disease.
At JHernandez Lawn Service, we know which grass type you have and cut accordingly. You don't have to think about it.
Your Schedule Should Shift by Season
Spring (March–May): Growth picks up fast. Weekly mowing keeps you ahead of it without ever taking too much off at once.
Summer (June–September): Peak growing season in DFW. Stick to weekly — consistent cuts at the right height keep your lawn looking sharp without putting it under stress.
Fall (October–November): Growth slows down. Weekly mowing continues to work well, and your final cut of the season should be slightly lower than usual to reduce fungal risk heading into winter.
Winter (December–February): Bermuda goes dormant. Mow only when the lawn genuinely needs it — a rigid weekly schedule in winter is unnecessary and can do more harm than good.
We adjust our schedule with the seasons so your lawn always gets exactly what it needs — never more, never less.
Signs Your Mowing Schedule Isn't Working
If your lawn looks rough between cuts, the answer usually isn't mowing more often — it's mowing better. Common culprits:
- Dull mower blades. A dull blade tears the grass instead of cutting it, leaving ragged brown tips. Sharpen blades at least once a season.
- Wrong cut height. Cutting too low scalps the lawn and exposes it to heat stress. Cutting too high leaves it shaggy and prone to thatch buildup.
- Irregular watering. No mowing schedule fixes an under-watered lawn in a Texas summer. Consistent irrigation is what keeps grass growing evenly between cuts.
These are things we handle automatically at JHernandez — sharp blades, correct height, consistent timing. One less thing for you to worry about.
The Bottom Line
Once a week, done right, is all your North Texas lawn needs. The key isn't frequency — it's consistency, the right cut height, and sharp blades. That's exactly what JHernandez Lawn Service delivers, week in and week out, across Carrollton, Plano, Lewisville, Flower Mound, Coppell, and 8 other DFW cities.
