I think mine is the den-phal type you guys are talking about. So how do you cut the flower spike? Is it the same as how you'll cut a phalaenopsis'? ANd also, I read somewhere that at one point all the leaves will drop, is this true?
Den Phals usually have a spike out of the top of one of the canes. You should be able to see where one starts and the other finishes. Just cut it off with sterile knife or scissors down close to where it joins the cane.
Den Phals don't drop their leaves every year like some other Dens. They may start to loose leaves on really old canes. One I have that was flowering 2.5 years ago is starting to lose one or two leaves on the cane which was in flower then.
Some Dens loose all their leaves every year in winter but if it's a Den Phal that would not normally happen.
