Mine got all moldy in December. It was just too warm in my basement, so I unwrapped them all and stuck them under moist peatmoss. Most of them have sprouted. I lost very few to rot. I saved every single bit anyway, so I still have too many to pot up. :-)

As I mentioned in an earlier post, I had only 1 lost tuber this winter. I had done some with the saran wrap method, and some with the recycled plastic grocery store bag method as explained last fall. None of the ones in the grocery store bags were moldy or soft. Only 1 of those in the saran wrap method was rotten. The moral of the story....both methods work well. The grocery store bag method probably takes up more space though. One major factor in this however, as pitimpinai suggests, is the temperature at which the tubers are kept. They must be kept cool.

I had a slight debacle, if there can be such a thing, after bringing my wrapped tubers into the basement to warm up/eye up. I had lost about 20 total in the winter, but all of a sudden they started molding like crazy- rot soon followed or was already happening internally and I had to throw out about 150, maybe more. That's about 15%, so still not bad. Could have been better though! It was quite disheartening to lose some varieties entirely, but I have enough to keep me entertained.

My lesson learned: unwrap if you store in saran and bring them into a warm environment!

The very few I stored in vermiculite in a bin were a bit dry, a couple died. I'm still a Saran fan for space saving.

Jroot, you should see me whipping out masterful paper pot liners thanks to your photo lesson last year! Still not an artist, but I learned enough to make them fairly neat LOL!

I am wondering where Bernie is hiding? I've been admonished for posting such an inquiry in a thread title, so I'm sneaking it in here :P Anybody heard word on him?

I don't take my tubers out of storage until planting time about mid May. Recently my loss has been somewhere around the 1 percent mark. In the earlier years it was about 6 percent and kept moving downward every year since. I believe the weaker stock were the ones that wouldn't keep over and the healthier ones survived. Thats one of the hidden benefits of plastc wrap storing I guess.
I'm really not hiding Annie. I've been busy with household chores and of course writing and making changes in the dahlia article we spoke of. Some of your tuber photos are incorporated to show more prominent eyes.
You may have lost some of your tubers when you took them out of storage into a warmer environment without unwrapping them. The temperature and humidity differential would cause condensation and support mold and fungus growth. As I mentioned earlier, I don't take mine out of storage and unwrap them until a day or two before planting.
Jroot, I tried some in the recycled plastic grocery bags. I'll let you know how they made out.

Good to hear from you Bernie. I was worried! I am certain the warmth on wrapped tubers led to their demise. prior to coming indoors they looked marvelous. There's always a new lesson every to be learned every year. I just hope that was my ONE big lesson for this season.

Bernie, I would be very interested in your findings. Please let me know.

For the past 4 years I have been storing my tubers the same way with minimal losses: I simply put them in a box and cover them with a hardwood sawdust(use to line my horse stalls). I store the tuber in my garage which stays around 50 degrees all winter and then plant them directly in the ground in may...the tubers multiply like weeds each year.
