Most homeowners mow their lawns regularly — but many are unknowingly making mistakes that damage their grass, invite disease, and create long-term problems. After 35+ years of professional lawn care in Terre Haute, IN, we've seen these mistakes over and over. Here are the five most common ones and exactly how to fix them.
Mistake #1: Cutting the Grass Too Short (Scalping)
This is the single most damaging thing you can do to your lawn. Cutting grass too short — known as "scalping" — removes too much of the leaf blade at once, which stresses the plant and exposes the soil to direct sunlight. This leads to:
- Brown, patchy areas that take weeks to recover
- Weakened root systems that can't handle drought
- Increased weed growth, since bare soil invites weeds
The fix: Follow the "one-third rule" — never remove more than one-third of the grass blade in a single mowing. For most Indiana lawns, this means keeping your grass between 3 and 4 inches tall during the growing season.
Mistake #2: Mowing With Dull Blades
A dull mower blade doesn't cut grass cleanly — it tears it. Torn grass blades turn brown at the tips and become more vulnerable to disease and pests. If your lawn looks ragged or brownish after mowing, dull blades are likely the culprit.
The fix: Sharpen your mower blades at least once per season, or more frequently if you mow often. A sharp blade makes a clean cut that heals quickly and keeps your lawn looking green and healthy.
Mistake #3: Mowing at the Wrong Time of Day
Mowing in the middle of a hot afternoon is hard on both you and your lawn. The heat causes the grass to lose moisture faster after cutting, increasing stress and the risk of browning. Mowing in the early morning when the grass is still wet can also cause problems — wet clippings clump together and can clog your mower or smother the grass underneath.
The fix: The best time to mow is mid-morning (after the dew has dried but before the peak heat of the day) or early evening. This gives the grass time to recover before nightfall without the added stress of midday heat.
Mistake #4: Mowing in the Same Direction Every Time
If you always mow in the same pattern, the grass will start to lean in that direction and the soil can become compacted along your mowing lines. Over time, this creates ruts and uneven growth patterns that are hard to correct.
The fix: Alternate your mowing direction each time you mow. Mow north-south one week, east-west the next, and diagonally after that. This encourages the grass to grow upright and reduces soil compaction.
Mistake #5: Ignoring the Edges and Borders
Mowing the open lawn but skipping the edges along driveways, sidewalks, and flower beds makes even a freshly mowed lawn look unkempt. Overgrown edges are one of the first things neighbors and visitors notice.
The fix: String trim and edge after every mowing. Edging along hard surfaces like driveways and sidewalks creates a clean, defined line that makes the entire yard look more polished and professional.
