  Amorphophallus koratensis problem (pictures)
From: "E.Vincent Morano" <ironious2 at yahoo.com> on 2008.11.07 at 21:43:46(18703)

My Amorphophallus koratensis had it leaf removed by the wind recently. Its cold now so it just went dormant. But as you can see from the pictures, it looks like two tubers stuck together when it is in fact one. The bottom one was the original tuber. Interestingly the bottom part is the same size as it was when I planted it in the spring. It now weighs 13oz. Anyway, a friend said I should cut the bottom off. I am not at all comfortable with that. What do you think? Do you think it might flower for me next year also? Is prety heavy.
Thank you

It's no problem at all. That tuber on the bottom is just the old tuber,
but there's a nice new fat one to replace it. I've made it my policy to
leave the old one in place and not break it off - unless it were to come
off with virtually no force. Just plant the entire thing next year and
everything will be fine. Whether or not it will flower is anyone's
guess. Only the plant knows!

I wouldn’t split the tubers. The top tuber willstill draw energy from the lower when it breaks dormancy. While I have noexperience with this affecting a koratensis, I did have the exact same thinghappen to a titanum. I simply planted the double tuber and it’sgrowing fat and happy.

Do not cut off the bottom. The tuber was regenerating itself and was
interrupted. The bottom is the original tuber, the top portion is the new
tuber. The old tuber is typically used up, at least partially, making the
new leaf. Then, the tuber is basically “regrown” absorbing the old tuber.
Sometimes the old tuber is not entirely absorbed by the new one. That is
okay, it probably will absorb it next growing cycle.

Happy days,

Do not cut off the bottom corm. This sort of thing happens often if
dormancy comes early for some reason. The old corm will survive the
dormancy and add to the food reserves of the newly developing growth
next spring. Also, cutting into corms simply exposes areas that are
now open for infection by pathogens and you shouldn't do it if you
don't have to.
