konjac bulb base rot.
Ok heres some info. My amorpohphallus tuber about 10 inches across has some rot on its base. at the philly flower show i had forced it to bloom for the show in which was a success. Now it was kept out of soil just a bulb sitting out up until the show in which i potted it in dry soil with a topping for show. So it bloomed and all and then when i took it home i left it in its soil which must of had some moisture in it. So i go to take the bulb out of its pot a week or so after and it had rot on its bottom. The top is fine and all but it rotted some of its base off. Now i had it out to allow to callous over in which it is almost pretty solid on the bottom. My concern is that now that it wants to grow i will need to pot it up and plant it for the summer. the shoot is up about an inch and a half and is ready to sprout. So i feel that when i pot it up and it gets watered that the base will continue to rot away and i dont want it to rot more then it did already. Any suggestions. I was thinking possible some powdered fungicide? here is a picture of the bottom of it.
