Fact or fallacy


The lower you mow your lawn, the less often you have to mow


Being in the lawn maintenance business for many years; customers would ask me to lower the mowing height with the objective of mowing less often. Nothing could be further from the truth. Most cool season grass can maintain very well at a variety of mowing heights. Perennial Rye can withstand mowing heights as low as .5”. Bluegrass can do very well at a mowing height of .75”. Tall Fescue on the other hand, does best at a mowing height above 2”.


The key to maintaining turf quality at a given height is to follow the 1/3 rule. Never mow more than 1/3 the green leaf at one time. If you maintain your grass at a height of 3”, you should cut it when it reaches 4” and cut it back to 3”. This allows for removal of 1/3 the green growth. With this rule in mind, the lower you maintain mowing height, the more often you have to mow.
