Kentucky Bluegrass Mowing Guide
Recommended mowing height: 2.5-3.5 inches for rotary mowers. Sod-grade KBG cultivars can be maintained as low as 0.25-1.0 inches with a reel mower for a golf-course look. Never remove more than 1/3 of the blade length in a single cut. During spring and fall growth surges, mow every 4-5 days — KBG grows fast in its ideal temperature range. Raise mowing height to 3.5-4 inches during summer stress to shade roots and reduce water loss. Always return clippings — they decompose quickly and return nitrogen to the soil. Sharpen mower blades frequently; KBG's fine blades show ragged cuts more than coarser grasses.
Frequently Asked Questions
What height should I mow KBG?
2.5-3.5 inches for standard home lawns. Raise to 3.5-4 inches in summer heat. Reel mower setups can maintain 0.5-1.5 inches for a sod-grade or golf-course look.
Can I maintain KBG at golf-course height?
Yes, with a reel mower, frequent mowing (every 1-2 days), and higher maintenance input. Sod-grade KBG at 0.25-1 inch requires more water, fertilizer, and fungicide than standard height.
How often should I mow KBG?
Every 4-5 days during peak spring and fall growth. Weekly in summer when growth slows. Follow the one-third rule — never remove more than one-third of the blade height.
