Mowing Tips for Cleveland, Zone 5b
Cool-season grasses grow most actively in spring and fall — expect weekly mowing in April–May and September.
Allow lawns to go summer dormant rather than forcing growth. The lawn recovers fully when temperatures drop.
The one-third rule is especially important in spring — never remove more than one-third of blade height when grass is growing rapidly.
Leave clippings on the lawn in cool weather — they decompose slowly and add organic matter.
First mow of spring should be at maximum height (75–90mm). Lower gradually over 3–4 mows.
