Last week the weather warmed up to around 80 degrees and it was a record high for this time of year. Lawn trailers of every walk of life jumped up out of hibernation and roared to life. The grass is still in its dormant state and a lot of people were aerating, dethatching, scalping, and doing spring clean up. I'll be darned if it is not snowing outside today and has been all day. My question is this...can it be harmful to the grass if you scalp it, only to have it snow again?
