Hi = we store all our squashes in the barn - not really frost proof though and have in the past lost a few. I always make sure the stem is left about 2-3" long and is well dried out. If I think some of them are not going to store I chop them up (after peeling etc) and freeze in cubes and the pigs eat the inside and peelings. Brilliant for adding to soups, stews, curries etc. No waste at all. Freeze courgettes in small dice for pasta bakes, soups, stews and the like.
