Very true
Height Of cut is critical.
Cut your lawn at 3.25-3.5.
If you cut too short the sun will heat up the soil too much. Crabgrass loves heat! If you simply keep your grass longer it will shade the soil keeping it cooler thus reducing crabgrass opportunities
Let’s be honest… crabgrass isn’t just “random” 😅
It’s not showing up because your lawn is unlucky—
It’s showing up because it found an opportunity.
Crabgrass loves lawns that are:
• Cut too short ✂️
• Low in fertility (especially nitrogen) 🌱
• Stressed from drought, insects, or disease 😬
• Thin and open with bare spots
• Compacted (hello driveways & sidewalks 👀)
Basically… when your good grass struggles, crabgrass moves in like it owns the place.
👉 It’s not the cause… it’s the symptom.
The real fix?
Build a lawn that can compete—thicker, healthier, and managed right.
Because when your turf is dense and thriving…
crabgrass doesn’t stand much of a chance.
