This plant really needs to be removed from the mount and divided. I am reluctant to do it because of the combination of lots of other plants needing attention and the renovation. However, if I don't do it soon I will have to wait another year. I really need all of the new root growth of each division to be in the new pot. If I don't do it this year, It will be ugly all year and not flower very much.
The growing space renovation is progressing. Today's task is to work up a materials list with the guy doing the actual work. I will collect the material and do some painting. The construction will begin May 16 and be full-time until it is done, maybe 4 days work.
