What is the biggest mowing mistake Indianapolis homeowners are making right now?
Hey, Jake here with Fine Touch Services. If your lawn turns brown and patchy every July, the culprit usually isn't bad luck or bad soil. It's how you're mowing.
The mistake almost every homeowner in Indianapolis is making right now is cutting the grass too short with a dull blade. Those two habits stack together, and your lawn pays the price all summer long. The good news is both are quick fixes once you know what to look for.
What is the one-third rule, and why does it matter?
The one-third rule is the foundation of healthy mowing. Never cut more than one-third of the grass blade in a single mow.
So if your grass is four and a half inches tall, you should only be taking off about an inch and a half. That's it. When you scalp the lawn down to two inches because you want to mow less often, you're doing three bad things at once:
You're stressing the roots
You're exposing the soil to harsh sun
You're basically rolling out a welcome mat for crabgrass
Crabgrass thrives where turf is thin and soil is warm. Short mowing creates both conditions on the same afternoon.
How tall should you keep your lawn in central Indiana heat?
In our central Indiana heat, aim to keep your lawn around three and a half to four inches tall all summer long. That height does two big things for you. It shades the soil, and it forces the grass to grow deeper roots.
Taller grass means deeper roots and way less watering. Deeper roots reach moisture that shorter, scalped grass simply can't get to, so your lawn stays green longer between rainfalls and your water bill stays reasonable through July and August.
Why does a dull mower blade damage your lawn?
The second fix is the blade itself. A dull blade doesn't actually cut your grass. It tears it.
Walk out a day or two after mowing and look closely. If you see frayed, white tips on every blade of grass, your mower blade is dull. Those white tips are open wounds. Shredded grass loses moisture faster, and lawn diseases move right in through those torn edges.
A clean cut from a sharp blade heals quickly. A torn cut from a dull blade is an invitation for trouble.
How often should you sharpen your mower blade?
Sharpen your blade every twenty to twenty-five hours of runtime. For most Indianapolis homeowners, that works out to about three times a season:
Once at the start of the season
Once again in midsummer
Maybe a third time in the fall if you're mowing late into the year
It's a fifteen-minute job at a hardware store, or you can swap in a spare blade and keep two in rotation. Either way, your lawn will notice the difference within one mow.
What is the easiest way to get a healthier lawn this summer?
Do those two things, raise your mowing height and keep a sharp blade, and your lawn will look better than your neighbor's by July.

Frequently Asked Questions
What is the best height to mow grass in Indianapolis during summer?
For central Indiana lawns, keep your grass between three and a half and four inches tall all summer. That height shades the soil, encourages deeper roots, and helps your lawn survive heat and drought with less watering.
How often should I mow my lawn in central Indiana?
Mow often enough that you're never removing more than one-third of the blade at a time. In peak growing season (May through June) that usually means once a week. In hot, dry stretches of July and August, you may only need to mow every ten to fourteen days.
How can I tell if my mower blade is dull?
Check the grass a day or two after mowing. If the tips of the blades look frayed, ragged, or white instead of cleanly cut, your mower blade is dull and needs sharpening.
Does cutting grass too short really cause crabgrass?
Yes. Cutting too short thins the turf and lets sunlight reach the soil, which is exactly what crabgrass seeds need to germinate. Mowing taller is one of the simplest ways to prevent a crabgrass takeover.
How often should I sharpen my lawn mower blade?
Sharpen every twenty to twenty-five hours of mowing time. For most homeowners that is about three times a year: at the start of the season, mid-summer, and again in the fall if you mow late.
