When I grew B-nut, I left them until the vine died UNLESS something started chewing on them. The skin gets tough, so it was not usually the first thing something would pick to chew on.This is my first year growing butternut squash. I see several squash in different stages of ripeness. I know they tan up a bit.
Any advise on when to pick?
I had to be sure that I got them inside before any frost.
