Amorphophallus Konjac stem wrinkling

[John2468]

Hello everyone 

I have an amorphophallus konjac which was doing great a week ago, but today when I went to water it, the stem was soft wrinkly. The leaves are still green. Is it going dormant or am I doing something wrong?

I grow a number of Amorphophallus but in pots only. They generally go dormant in Oct./Nov. and regrow starting the following April. After the leaves die back in the fall, I let the pots dry out totally (the bulbs and plant fluids are very caustic to my skin, so I wear neoprene gloves under cotton garden gloves and a face mask to work with them). I rinse the bulbs with the hose, then dry them for a couple days in the sun. Then I cover them with garden dust and store them in paper bags in my garden shed over the winter. Come April I repot them in garden soil with handfuls of bone meal and set the pots around the yard to germinate. When bulbs are mature, they send up the flower first, later the leaf stalk.

I can't explain why yours are dying back so soon or so late. A few bulbs have escaped my pots to the yard but even they resprout in the spring and go dormant in fall.
