Do you scalp your lawn? How not to ruin it...

Do you cut your grass - or do you trim it? 

Just don't scalp it. Scalping the grass is when you cut it too short or let it grow too long before mowing it. Cutting off more than 1/3 of the height is super-stressful on grass and will damage your lawn.

It’s best to cut, or trim your lawn once or twice a week to prevent scalping. If you miss a week and your grass is long, it’s better to cut it twice. Adjust the blades up high for your first pass. Wait a day or two and then cut it again to the desired height.
