Does one "prune" a Purple Robe/Potato Plant?
I have two of these plants that I planted this summer. They were cut into a 5 foot high "tree" formation presenting in a globe of purple flowers. We had a snow fall and the plants were covered for three days. Now all the stems in the periphery are basically dried and, I guess, dead as they snap off when tweaked. There are no leaves present. Is this the norm or have tjhey died? Should I cut the branches or prune back...maybe until I see greensticking?
On plant Solanum rantonnetii
