Planted my first Angel Trumpet this spring from a cutting. It is starting to get cold in East Tennessee and I know it won't winter over outside and I have no room to store it if I dig it up and pot it. I am thinking about taking some cuttings and placing them in a bucket of water. Hoe long can I keep them in that bucket and at what temperature range. If I do it now it will be 6 months before I can plant them outside.
