Thank you all, it's reassuring to know that I haven't damaged them in some way, although I am a little disappointed that I didn't save a big one for a marrow wine experiment. I'll see how they go over the next few weeks then clear them to make way for my garlic, pak choi etc.
No Black Magic as yet PH, although I will keep am eye out for anything suspicious, like a quick swipe from his boot on the way past!
