Ladbrokes it is not a war!! I am sure you love your plants and I am glad that some are doing well.
Whereas climbing beans, courgettes and squash need heat which we certainly have not had recently (most of my squash are under fleece and growing alright, I plan to remove the fleece on Monday), however I think that from about next Weds we shall notice a rise in temperature and some blue sky!
PS about mildew on onions, it is difficult in an allotment of your neighbour has infected onions as mildew can spread quite a way, on the wind I think. I would make an allotment rule to grow only spring sown/planted onions.
