Take them before it gets cold. Last season we had a few 50 degree nights and I think that had a negative effect on my winter squash storing capability. I lost alot to ooze and rot.

Check online whether or not you should leave the stem on. Some WS/pumpkins store better without. University Ag sites are usually good for that~

I left mine on a sunny porch for a few weeks (mostly upright) and then moved them onto the bed in a back bedroom for a few weeks more. (Laid down, turning them occassionally.) Then down to the basement on slatted shelves where the temps range from 60 to 70 degrees until late April or so. Even with the warmer temperatures, I still have a handful of butternuts & a sweet meat down there, but they're not looking their best anymore and I have to check & pitch the moldly more frequently. ;)Unlike other root cellar storage, WS & pumpkins prefer it on the warm side. Some people just bag up their WS after curing and put them under a bed.
