Yes, cutting no more than 1/3 of the total height is about right.Originally Posted by dabvu2498
Basically, you're wounding the grass when you cut it, so by taking off no more than that much you are always assured that there is sufficient plant mass left to direct energy into healing the plant. Another thing that helps your grass rebound quickly after mowing is to keep the blade sharp. It's just like your skin- a cut from a razor heals faster than a scrap on the pavement.
