  Propagation by Leaf Cutting
From: "James W. Waddick" jim-jim at swbell.net> on 1999.09.13 at 08:53:45(3648)
Dear All;
Recalling the success in propagating some Amorphophallus from a
leaf cutting, I wonder how common (or possible) this method of propagation
is in aroids. Can one propagate Alocasia, Colocasia, Anthurium etc. ?
Anyone ever attempt this or have success ?
Curious to hear methods and successes as well as failures.

In Amorphophallus the leaf is cut with a short or no petiole and
the area between the petiole and the leaf blade is just covered in the soil
medium. High humidity may result in the formation of bulbils. Sorry for
vague details, but something seems to be going on here.

Appreciate any related comments.

Thanks Jim W.

I've been doing some Aroid propagation experiments this year with almost
100 percent success.

I've had success with several species of Amorphophallus and Psuedodracontium.
And in a couple of weeks, may be able to add Caladium to the 'successful'
category.

Unlike some others, I do not use the upper part of the leaf. I use only
the petiole. I cut into 3-4 inch sections and stick them in a mixture of
pinebark and perlite, then put them underneath a trash bag for 6 to 8
weeks. After that the part of the petiole cutting above the ground has
whithered, but a bulbil has formed underground.

One particular failure was with Synandrospadix...only tried one single
cutting. I doubt this would have worked as the petiole tissue was
quite 'airy'.

I'll be interested to know if you're successful in propagating Caladium by
your
petiole cutting method. As far as I know, it's accepted that they cannot be

Alan Galloway can't be reached right now but he said:

OK, the leaf has withered and there is a bulbil at the base. Help! What
do I do now?

Thanks.

DO NOTHING! Keep it slightly moist and do nothing but wait for Spring....

Dear MJ,
My guess (GUESS, mind you!!!) would be to wait till the petiole was
completely dry, then carefully transplant the base with new bulbil to good
growing soil, water and wait for a new leaf.
Good luck,
Julius

Dear MJ,
I believe Dewey`s advice (below) is the better way to try, so ignore my
earlier post.
What species were you sucessful with by using Alan`s method??
