My lawns range from 7-10 days. Some properties are tenant dwellings and to save on costs the owner asks to lengthen cuts. Even then those owners are willing to spend more on lawn/weed maintenance. In the fall when the growing season comes to an end, or due to lack of precipitation, I'll lengthen cuts to every two weeks as I refuse to cut lawns on schedule that haven't grown. It makes no sense to stir up the dust and not really cut the grass due to slow growth. I see some operators out with their crews mowing 'dirt', which might be part of a contract so they don't have much choice, but I would just let the lawn be. My light commercial and residential accounts range from 25-60/week. I have one long term client who keeps asking me to cut her lawn more frequently. If it grows more than 1" after I just cut it, she calls asking me to cut it again. I say no, because it's not economically feasible for me to go all the way out there with the truck and trailer just for one lawn. Each year I reassure her that I make my rounds no less than once a week and she says she's OK with that, ha. At most, grass might grow upwards of 2" within a one week period in optimal growing conditions. This is southern Ontario area, so the growing season slows down around early September. I don't look at it as a scheduling nightmare. My only issue is bringing a new client on board, and working that property into the weekly route schedule.
