  going dormant...
From: Kevin Martyn <martyn at telcomplus.com> on 1997.08.04 at 12:56:25(1010)
Hi all!
Every time I have an Amorphophallus enter its dormancy stage I leave =
the leaf alone until it completely abscisses, with the belief that I may =
adversely affect the plant should I cut it off. This often leaves a big =
mass of leaf hanging off the side of the bench because the stem has =
collapsed half-way up. My question is...how far into dormancy do bulbous =
aroids drain any remaining sugars from the leaf and stem? Would any harm =
come from topping a plant before it drops off completely by itself?

My experience with Amorphophallus is limited, but generally with any
plant I always ask myself what would normally happen under natural
conditions with any particular plant. In the case of Amorphophallus, the
entire leaf keels over, becomes somewhat slimy, and eventually dries up.
Usually at this point I will tug ever so slightly at the dried petiole to
see if it is loose. If it is not free I will leave it alone.

Granted, having dried up petioles hanging from pots is not pretty, but my
feeling is that the time to remove the old growth is when the tuber is
willing to part with it. At this time it is reasonable to assume that the
tuber has sealed the opening and is capable of protecting itself from
disease and other intrusions.

In my 10 years experience with Amorphophallus I learned that no harm is done
when you cut the leaf of while in decay but not yet entirely rotten. I also
do it to avoid rotting to proceed to the top of the tuber that MAY result in
bacterial infections of the tuber.

Cheers, Wilbert
