SESK: Stuff Everyone Should Know · sesk.info/home-mow-third
How much of the grass blade should you cut off in a single mowing?
No more than one third.
- Up to half
- As much as possible, so you mow less often
- No more than one third ✔
Why: Cutting more than a third stresses the plant, and scalped grass takes longer to recover. Regular mowing at the right height keeps grass dense and keeps weeds down.
Huh, didn't know that: Dull mower blades leave jagged edges that make grass more likely to get diseases.
Why didn't the crops' relationship work out? They were dating lawn-distance, so they weren't really fielding it.
