I would take them outside and lay them on the porch and let them stay there
for a week or so (as long as it isn't going to freeze). This will let them
dry out more. While they are "curing" for storage, the moisture escapes
through the stem. That is probably what you are seeing on yours. I still
have 5 winter squash in my storage room from picking last September and
October (two are butternut).

I've harvested about 20 or so Butternut squash this year and recently
noticed that there seems to be some mold starting on the stem. Is this due
to the area I'm storing them in not being cool enough? If so, if I move
them
will the mold stop growing or should I peel and freeze them now? TIA
