it's almost frost time here in MI and my husband wants to mow down rows of well-established peonies and daylilies. Should this be done? .....will it help or hurt?
Not tree peonies though ;)
My husband's Mother had several peonies and when she couldn't garden anymore, my Father in Law forgot they were there and mowed them repeatedly for several years. It wasn't till he was himself ill and couldn't mow the lawn that we discovered the peonies in the spring when they came up and bloomed! It may have set them back, but it sure didn't kill them! I dug one up for my own yard before the house was sold. It has sat in a pot with weeds and little soil all summer and still looks fine. These things are dang hard to kill once they have established.
