Actually, I do trim the necks when I have pulled them out of their pots and the leaves have finally turned yellow. I take a steak knife and carefully look inside just to make sure there isn't a bud lurking and then I make a neat slice. It dries in a day or so, and looks really neat. I don't really get around to doing all of them, but the ones I do cut just look neater. Now, those that don't go dormant, of course I leave them alone. If you're growing them as houseplants and they never loose all their leaves, then I guess I'd leave them alone, just my opinion....

Thanks for answering Donna. I don't let mine go dormant, but I think Mother Nature knows that they need a cycle, because even the ones I've kept indoors all year are having their VERY LONG leaves turn yellow. I cut them off at this time of year and fresh ones grow.

It made sense to me that when the last leaves come off, I can cut the neck down. Like you - I'll be careful not to snip any buds!

Merry Christmas!
