I stand corrected Lyn. I typed before I put my brain in gear.Even tho I have not read Mr LeGrice's work I have actually most of the time followed his advice.I have many times cut off old canes that have become non-productive to get them out of the way and out of sight because they have become ugly compared to new growth.I wasn't thinking of forcing basal growth or plant rejuvenation. But like I said if it works thats great. I will be paying more attention to old growth that needs to come off for sure!!
