CuttingaThirdoftheGrassBlade

Itisbesttocutonlyaboutathirdofthegrassblade. Cuttingmorethanthatisnotrecommendedunless grassissparse,oritislatefallwhengrassgrows moreslowly.

AlternatingtheMowingDirection

Alternatethemowingdirectiontokeepthegrass standingstraight.Thisalsohelpsdisperseclippings, whichenhancesdecompositionandfertilization.
