which to cut?
I have a pink grandaflora that is about 5 ft tall. the old canes are about the size of a nickle and quarter in dia. and about 16 inches long with this years growth added on to that making the 5 ft. I also have newer growth coming about6 inches from ground the size of a dime. Of course the dime size is coming out and has grown in amoungst the older canes. Wondering which to cut back. Plant is healthy as far as I can determine. Please ask questions if needed and all comments are appreciated. Thanks. Pembroke
