Mowing Height with Fungus: 3 Inches Is Ideal Regardless

Fungus on lawn. Cut shorter or longer than 3"?

3 Inches Is Standard

Fungus presence doesn't change mowing height. All lawns have fungi; disease only when specific ones explode. Mow at species-optimal height (3" for most cool-season).

Don't Scalp

Short cuts stress grass → more disease. High cuts trap humidity → more disease. 3" balances both.

Height is constant; disease management is cultural (water, N, air).
