Lawn care tips
How Often Should You Mow Your Lawn in Tallahassee?
Through the growing season, which in Tallahassee runs roughly April into October, most lawns here need mowing about once a week. In the cooler months that stretches to every two or three weeks. But the calendar is not really what decides it. The rule that matters is never removing more than one third of the blade in a single cut, and how fast your lawn hits that point is what sets your schedule.
The one-third rule, and why it decides everything
UF/IFAS puts it plainly: mow often enough that no more than one third of the blade height comes off in any single mowing.
The reason is simple. Grass blades are how the plant feeds itself. Take too much at once and you remove its food factory, so it dumps energy into replacing leaf instead of building roots. A deep root system is exactly what carries a lawn through a North Florida August, so scalping in June is a bill that comes due in the heat.
Run the numbers on your own yard. If you keep St. Augustine at 3.5 inches, one third is a bit over an inch, so you mow when it reaches roughly 4.5 to 5 inches. In peak season that is about a week. In November it might be three.
Mowing heights by grass type
| Grass type | Recommended height | What that means in peak season |
|---|---|---|
| St. Augustine | 2.5 to 4 inches, dwarf types no lower than 3 | Weekly through the growing season |
| Centipede | 1.5 to 2 inches | Slower growing, stretches further between cuts |
| Zoysia | 1 to 3 inches | Varies a lot by cultivar |
| Bermuda | 0.5 to 1.5 inches | The fastest here, every 3 to 5 days |
| Bahia | 3 to 4 inches | Every 10 to 17 days |
Most Tallahassee yards are St. Augustine or centipede, and those two want very different things. Cutting centipede at St. Augustine height leaves it thin and stemmy, and cutting St. Augustine at centipede height scalps it. If you have inherited a lawn and are not sure which you have, that is worth settling before you set the deck.
Higher is better through the summer
Within the range for your grass type, err toward the top of it from June through September.
Taller blades shade the soil beneath them, which keeps root-zone temperatures down and slows evaporation, so the lawn needs less water. That shade also denies light to germinating weed seeds. A lawn cut high in summer is doing free weed control and free irrigation at the same time.
The things that matter as much as frequency
- Sharpen the blade. A dull blade tears rather than cuts. Look closely at your grass a day after mowing: clean cuts stay green at the tip, torn ones turn white and frayed, and every one of those is a wound.
- Change direction. Mowing the same line every week presses the grass into a permanent lean and compacts the same wheel tracks. Alternating direction keeps growth upright.
- Leave the clippings. Short clippings break down quickly and return nitrogen to the soil. They do not cause thatch. Bag only when the lawn has gotten away from you and the clumps would smother what is underneath.
Letting it get away from you
Everyone misses a week. When you come back to a lawn that is well past its height, resist the urge to take it all off at once. Cut at the highest setting, wait three or four days, then cut again slightly lower. Two passes cost you one extra trip and save the lawn a serious setback.
Want it handled on a schedule?
Consistent mowing height and timing is the single biggest factor in whether a lawn looks thick or patchy, and it is the part that is easiest to let slip in July.
We run regular mowing routes across Leon County, cutting to the right height for your grass type on a schedule that keeps the one-third rule intact. Request a free quote or call and we will work out what your yard needs.

Common questions
Can I mow every two weeks instead of every week in summer?
You can, but through the peak growing season it usually means breaking the one-third rule, and that is what causes the scalped, strawy look people blame on the mower. If a fortnightly schedule is what fits your life, raise the cutting height so there is less to remove each visit, and expect the lawn to be thinner than a weekly-cut yard next door.
If I cut it shorter, will I need to mow less often?
It is the most common shortcut and it backfires. Cutting low removes the leaf area the plant uses to make food, so the grass responds by pushing new growth harder, and it grows back faster rather than slower. You also expose soil to sunlight, which is an open invitation to weeds, and you shorten the roots at exactly the time of year they need to be deep.
Is it bad to mow wet grass?
It is worth avoiding. Wet blades tear instead of cutting cleanly, which leaves a ragged edge that browns off and gives disease an entry point, and wet ground ruts under the weight of a mower. On heavier clay ground north of town it is worth waiting a day rather than leaving tracks you will be living with for months.
