I just obtained two large growth tips with about 4-6 inches of tuber below the tip from mature sarian plants at work. The plants were about 8 foot tall and in order to save space in the greenhouses at work they cut the top of the tubers off and were going to hit the compost. So considering that there was tuber intact below it i took them to overwinter. I was wondering if any one has experiences with how long they would need to callous over. They were just cut 2 days ago and the tuber is 5 inches in diameter. The leaves were all cut back to the tuber except for the center two in which were cut back to where the newest leaf would pop from.

I figured i would let them callous and pot them up into snug containers for the winter considering they will overwinter in the house close to a window sill.

Any thoughts appreaciated thanks.
