Keep Your Lawn Healthy During Hot Southern Summers
North Carolina summers are no joke. When temperatures climb into the 90s and stay there for weeks, your lawn’s needs change—and so should your mowing routine. Whether you’re trying to maintain a lush look or simply protect your grass from heat stress, mowing the right way makes all the difference.
Why Mowing Frequency Matters in High Heat
In hot weather, your lawn can become stressed more easily. Mowing too often or too short can damage the grass, expose roots, and lead to brown patches. On the other hand, letting it grow too long can create other issues, such as fungal disease or pest hiding spots.
General Rule for Summer Mowing in NC:
- Mow every 5 to 7 days during hot stretches
- Never remove more than one-third of the grass blade at a time
This allows your lawn to stay strong, retain moisture, and bounce back after each cut.
Grass Type Makes a Difference
Different grass types respond differently to heat and mowing. Here are some common North Carolina grasses and how often they should be mowed during 90-degree weeks:
- Bermudagrass: Mow every 3–5 days; keep it at 1.5–2 inches
- Zoysiagrass: Mow every 5–7 days; keep it at 1.5–2 inches
- Tall Fescue: Mow every 5–7 days; keep it at 3–4 inches
- Centipedegrass: Mow every 5–7 days; keep it at 1.5–2 inches
- Bahiagrass: Mow every 5–7 days; keep it at 2.5–4 inches
Best Practices for Mowing in Extreme Heat
When the heat is on, adjust your mowing approach to reduce stress on your lawn:
- Raise the mower height: Taller grass shades soil and retains moisture better.
- Sharpen your blades: Dull blades tear grass, leading to disease and brown tips.
- Mow during cooler hours: Early morning or evening is best to prevent additional heat stress.
- Leave the clippings: They break down quickly and add nutrients back into the soil.
- Avoid mowing drought-stressed grass: If your lawn is dry and crunchy, delay mowing until after rain or irrigation.
Signs You’re Mowing Too Often or Too Short
Watch for these warning signs that your mowing schedule might be doing more harm than good:
- Browning or scalping along the mower path
- Grass thinning out or feeling dry and brittle
- Increased presence of weeds or bare spots
Stay Flexible with Your Routine
Summer mowing isn’t one-size-fits-all. If you’ve had a week of intense heat with no rain, it’s okay to skip a mow. On the flip side, if you’ve had rain and the grass is thriving, you might need to mow twice in one week.
