Yellow Hue After Mowing: You're Cutting Off the Green

Colorado, Kentucky bluegrass. Nice green until mowing—then yellow hue. Sharp blades, new blade, Scott's Turf Builder II every 6 weeks. Why?

Simple Optics

Only sun-exposed blade parts are green. Lower portions are yellow/brown. Mowing removes green tips → reveals yellow base.

Fix: Mow More Often

• Frequent mowing keeps lower blades sun-exposed → they stay greener.
• Never remove >1/3 blade height per cut.
• Raise mower to 3–3.5".

Yellow after mowing = mowing too infrequently or too low. Adjust schedule, not fertilizer.
