I am asked frequently this time of year how long will we be mowing grass.
It is November and typically we don’t think of mowing at this time of year.
The image below is of a lawn we mowed today November the 9th.
The question when to stop mowing can be answered by the same rule which tells us when to start mowing,
namely the 1/3 rule. This rule says that we should never take more than 1/3 of the growth off of the stand of grass. So then, the trigger to mow is when the growth exceeds 1 and 1/3 of the mowing height. When do we stop mowing? When the top growth fails to exceed this height. When will this occur? Not by the calendar, but when climatic conditions create an unfavorable environment for the grass to grow whether that is October or December.
