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'.
