Sorry, I didn't take any pictures. Yesterday I dusted the area with cinnamon and just left it on the table to dry out. Today the rot area is dried up, and it looks like pitted prune.I have carefully put the plant in a slender pot with dry Dyna-Rok. The rest of the cane looks fine and the flower stalk seems to be bigger today.
I did talk to the Ecuagenera representative, but since it is a pre-ordered plant, they didn't have any other ones at the sale. Instead, I picked a totally different plant, a Masd. coccinea as a replacement
