Unfortunately, it looks like I have moles. Of the Blue Boy, only one had any tubers left--all the others were eaten, sometimes leaving the hollow shell behind.

Fortunately, fully splitting that one Blue Boy gave me six, or one more than I started with...!

I store poorly and rarely lose a tuber. Dry seems to be the key, moreso than temperature.

I'm far from an expert at storage, still learning from experimentation. My failures have taught me to dry them as much as possible prior to storage, not seal them up, check for trapped condensation and cross fingers. Of course, you leave them out, and they can shrivel to husks. I store at 65 degrees, so mold is more of a problem for me then most. Temps don't keep mine from going dormant, but high humidity WITH warmth does... Wakes them right up, ready to grow.

Every storage area is a microclimate into itself, and what works for one grower utterly fails for another.

I also store "too warm," currently clocking at 61 degrees (I keep a radio thermometer down there for the sprouts and seedlings, there's no reason to move it during other parts of the year).

I lift, dry a bit in air outside (rarely more than a couple hours), pop into paper bags with the tops open, and drop them in the cellar. After a few weeks, I close the tops of the bags. There's never more than six small or four large tubers per bag, and the bags are the garden trash collection ones, so very large.

Post that, keep an eye on them once a month or so. If they're shriveling, spray with water and open the bag again. If they're only a little wrinkled, ignore.

It's rare that I have to spray with water, and the humidity in the cellar (sharing the air system with the first floor) averages about 35%.

Six on one, half dozen on the other. Peat moss is really, really dry out of the bale, so I'd actually damp it faintly and then mix. Not more than a single mist shot from a sprayer.
