First time to post a message. My questions is twofold. I have two plants that are 15 years old in very large hand made containers with casters. Both plants are 0ver 10 ft. tall and are in bloom now. My garage door is 9 ft., so needless to say it will be a problem to bring them is during cold spells this winter. Should I cut them now so as to get new cutting started and let the plants grow new tips, or wait untill they start to go dormant? If I wait how do I store the cutting untill spring? I hate to loose my blooms now.
