i just watched my neighbor scalp his bermuda lawn yesterday.. and also had a customer tell me he wanted me to do his next app before he scalped it for the winter. i guess its for the look of it. but is there just something i don't know about doing this? i've just always kept it a little higher in the winter myself.. common sense tells me this will help keep weeds out better. not to knock my neighbors lawn, his lawn always looks good.
