Krstofer I saved two Amorphophallus Konjacs this way. Cut out the rotten part, rinse with alcohol, tap dry with a tissue, pack with wood ashs, then sit is a sunny spot. It works great for me, but I don't think folks like this method, cos they seem to feel that their has to be a more dificult procedure. :) Arum

Cut it out & stuff the hole with ashes? I've got a stove right there plenty of ashes to go around.

Thanks for the info-

Yes, but don't forget the alcohol. The alcohol evidently kills the bacteria. And make sure to tamp the area gently with a tissue, THEN pack it with wood ashs. :)

Well.. They're in pretty sad shape:

I found another one who was havin' a problem..
SO I cleaned them with a toothbrush & some bleach-water (don't have any alcahol) and have packed ashes into all the bad spots..

In the windosill they go- With crossed fingers I hope..

Well, I don't know about the bleach, but you can try it. They have alcohol at the dollar store cheap. I had one Konjac that had a huge hole in it because of the rot, and then I put it in the back room where it's cool. That wasn't a good idea, cos I checked it about a week later, and it wasn't drying right, so I put it in a sunny window, and it did great. Hope yours does well, even though you used bleach. :) arum

Ive had the same problem. I just cut out the bad spot making sure to get all the rot and taking as little good tissue as possible. I didnt sanitize mine (probably should have) just put them in a mildly warm dry place for a few days. After they dried and calloused over they got stuffed back with the rest of them. It seemed to work.

Good luck! Jeff

WeLL Jeff, I say if it's not broken, why fix it? I mean if it works for you, that's great, I mean... :)

Well, I figured "bleach kills everything".. Alcohol may not. But we'll see. I pretty much figured the big one was a lost cause anyway- We'll see.

ANyone know what the heck causes this anyway? It did rain for about a week before I dug everyone, but.. Seems like it happened Really fast!

It may be just poor drainage. Then again the wire worms, pill bugs, etc do damage, open up a wound, so the bacteria gets in,- and there you have it. I'm not real knowledgeable concerning these bulbs in general, but that's what usually happens with other bulbs, or it's REALLY some kind of disease. I have so many of them now, the only ones I'm really concerned about are the good sized ones. :) Arum

Probably the rot is caused by a microbe in the soil that starts up in the absence of enough calcium in the soil. Not all bulbs or corms are susceptible at the same rate. Calla is especially susceptible with about 99% total liquification. Test your soil, use fertilizer with calcium and micronutrients. Sandy
