My Dens are driving me nuts. They have branched into two ft. thuick stocks with leaves at the very top. They bloom beautifully but are so hard to handle or even to keep balanced in a pot. With the canes so bare they aren't very pretty except for the flowers as pretty as ever. What does one do with these????? If you prune will they sprout kekei or something. These bare canes.... can you remove them as long as you have a good size plant left.
