Dave and Frillylily, thank you! Our low temps are going to be right around the freezing mark tomorrow night and Saturday night, but then after that it looks like we'll be back in the 40s for at least a week. My gourds are big and don't seem to have grown much , if any, for quite some time now, so I'm pretty sure they're full size -- but the stems are still green so I'm really hoping they can hang on in the outside temps for a while longer. They're growing on my hoop trellis, so I think I'll throw a tarp over them for the next few days to give them a little extra protection. If it gets too cold and they're still really green, I wonder if there would be any advantage to leaving some of the vine attached when I pick them -- would that help with the drying process in any way?
