Visited my allotment vineyard for the first time in a while. It's pretty difficult trying to work organically when (a) you haven't got much time and (b) when it has rained for most of June. My sole defence against oidium (a fungal disease that affects Vitis vinifera vines) is sulfur, and when you apply this in the rain it gets washed off. I applied some more today, but there are already signs of oidium on some of the grapes. Not good. The vines are also amazingly vigorous, and you can hardly tell where one starts and one ends. Next year I'll try to implement a vertical trellis and grow the vines in neat hedges. I'll likely have plenty of time to spend on the allotment then.
Aside: Nice to see the sunshine again after so long.
