Harvesting: Harvest when the squash's rind is hard enough that you can't dent it with your fingernail and before first frost. Cut stem, (don't break it off) leaving 2" of stem attached, which keeps the squash whole, leaving no opening for infection. Though fruits are hard and may seem indestructible, treat them gently; bruising can spoil squash.
