Vine problems

Hello everyone, I live in Italy and am growing some vines in my garden, one is a rosé grape and the other is called American grape or "uva fragola" (strawberry grape). Both varieties seem to be having a bit of trouble. A lot of the grapes seem to be "drying up" on the vine without maturing. A lot of the leaves have a yellow/brown hue. We have been eating the few grapes that have matured but they aren't maturing very well. We have been treating the plants with "verderame" (copper based treatment) and watering regularly. Do you have any suggestions? Thanks!

I'm in Italy too. If your summer was anything like ours, everything basically cooked. I've got three grapes, two in large pots. I had to pour tons of water on them. The yield is nothing like it has been in the past.

yes it was very dry! We watered them profusely but they're still not in good shape. Even the veg and tomatoes suffered this year.

Dry and unrelentingly hot here. The worst season I've ever had for everything in the vegie line. Even the female pumpkin flowers were cooking and withering before they had a chance to open. Now that it's cooler, I'm getting pumpkins setting every day. Except yesterday and today has seen winds of 40+kph and my French beans - that I'd just started to harvest - are being destroyed. You can't win!
