Every spring, one of the most common questions we get from homeowners across east-central Indiana is: "When should I start mowing?" It seems simple, but getting the timing right can make a real difference in how your lawn performs for the rest of the season.
Watch the Grass, Not the Calendar
There's no single date that works for every lawn in Indiana. Spring weather can vary wildly from year to year — some years we're mowing in mid-March, others not until April. Instead of picking an arbitrary start date, pay attention to your grass. You're ready to mow when:
- Your grass is actively growing (not just greening up)
- Blades have reached 3 to 3.5 inches in height
- The ground is firm enough to walk on without leaving footprints
- Daytime temperatures are consistently above 50°F
In most of east-central Indiana — from Muncie to Portland to Winchester — this typically happens somewhere between mid-March and mid-April, depending on the year.
The One-Third Rule
Once you do start mowing, follow the one-third rule: never cut more than one-third of the grass blade in a single mowing. If your target height is 3 inches, don't let the grass get taller than 4.5 inches before you mow. Cutting too much at once stresses the plant, weakens the root system, and makes your lawn more susceptible to weeds and disease.
Set Your Mower Height Right
For cool-season grasses common in Indiana — Kentucky bluegrass, tall fescue, and perennial ryegrass — we recommend a mowing height of 3 to 3.5 inches throughout the growing season. Here's why:
- Taller grass shades the soil, which reduces weed germination (especially crabgrass)
- Deeper roots develop when blades are kept at the right height
- Moisture retention improves, meaning less watering in summer
- The lawn looks thicker and healthier overall
Common Early-Season Mistakes
We see a few mistakes every spring that are easy to avoid:
- Mowing too early on wet ground. If your mower is leaving ruts or the soil feels soft, wait a few more days. Mowing on saturated soil compacts it, which hurts root growth all season long.
- Scalping the lawn. After a long winter, it's tempting to cut the grass short to "clean it up." Resist the urge. Scalping removes too much leaf tissue and exposes the soil to sunlight, which is an open invitation for crabgrass and other weeds.
- Skipping blade sharpening. Dull mower blades tear the grass instead of cutting it cleanly, leaving ragged tips that turn brown and invite disease. Sharpen your blades at the start of every season — or at least every 25 hours of mowing.
- Bagging clippings unnecessarily. Grass clippings decompose quickly and return valuable nitrogen to the soil. Unless you're dealing with a disease issue or the clippings are excessively heavy, mulch them back into the lawn.
