What’s the ideal mowing height for tall fescue?
During spring, summer, and early fall, aim to mow tall fescue at 3.5 to 4 inches. This sweet spot keeps your lawn looking lush and supports healthy root growth.
Why does mowing height matter so much for tall fescue?
Because grass blades are your lawn’s solar panels! Taller blades mean more photosynthesis, which = deeper roots, better drought tolerance, and overall resilience. It also helps shade the soil, slowing weed growth and reducing moisture loss.
What happens if I mow too short?
You risk stressing the grass, weakening roots, and inviting trouble like weeds, pests, and disease. It’s like giving your lawn a bad haircut—it takes a while to recover!
Can I just let it grow super tall then?
Not a great idea. Excessively tall grass can hide pests, trap moisture (hello, fungus!), and give your lawn a messy look. It’s all about balance.
Any mowing tips for tall fescue pros?
Absolutely:
- Never cut more than 1/3 of the blade at a time
- Keep mower blades sharp to avoid shredding
- Adjust your height by season. For example in mid to late fall, start lowering the mower height with each mowing so the height is approximately 3 inches by the last mowing of the year to help it overwinter.
💡 Bonus Tip:
Mow high, mow smart! Keeping your fescue tall and trimmed is one of the easiest ways to grow a healthier, tougher lawn.
