I have several varieties of wandering jew in a pot which I purchased this summer. I have trimmed about 1/2 of the length off. Would trimming the plants back significantly to where the vines would be about 6" long help rejuvenate them? The leaves have fallen off the root part of the stems but they are still growing well at the ends. I really don't want to have to replant them. I keep them outside during the summer.
