Hi Tricia, I have no experience about Jarradale behaving any different to any other winter squash, personally I would tend to leave it alone but you must decide about that, it is a vigorous plant but so is Queensland blue,so can't help you with this one, there is always the chance that it is not Jarradale, mistakes can happen..it was not saved seed though. Maybe you are getting something different. I will be interested to watch the progress with you.
