Re: [Aroid-l] Amorphophallus titanum seedling query

I've only got 13 of them, but they all sent up extra petioles. Some were very fast about it, some are just now putting up a second petiole after 18 months, but I'm sure my conditions are far from optimal!!

I also have absolutely no qualms about bare-rooting them when they are this small (up to around 3 feet tall) and re-potting to give them room when they put up an extra tall petiole. If you are a bonsai grower at heart then bare-rooting these to repot is trivial and you should have no problems at all doing it. I remove all the soil to check the roots and tuber before putting them in a bigger pot with fresh soil. Better to repot than have it be 3 feet tall in a 6 inch diameter pot that is 4 inches deep and then falling over (that would be my problem).

Sounds like your are doing well, and hopefully mine will continue to behave themselves.

Hi Paul,

I would say that is quite normal that titanum sends up up to 3 leafs
before it enters the first dormacy.

At least I have seen the with some of by babys. Have a look here:

I have to add that this plant is from tissue culture, however I have
read this about seedlings in an austrian Amorphophallus-forum as well.

I would not repot your vigorous seedling in order not to disturb the
roots. I find the root growth of my plants always poor, but this may be
also due to a suboptimal substrate.
Another point aginst repotting is that these Amorphs are often shown to
grow happyly in rediculous small pots and as they do so, it is probably
only possible by regular and heavy fertilizing. If the feeding is poor
they will show deficiency symptoms before they starve to death and then
it is always early enough to look after propper fertilizing again.

Good growing,
