i just tie them back with long twist ties bent like hooks on each end,the large leaves retain nutrients and hormones to help the plant grow more vigorous,and they photosynth all the usable light,that creates more growth energy and healthy stock,by the way,cathy & notannovice are very knoweledgable growers,but this is just my prefered method and my opinion,so i guess it's your call,best of luck to you in whatever method you decide to use....bonbon
