we have strong winds also (right now) and I dread to go out to the allotment to see what happened.
I'm trying to keep my polytunnel intact at the moment ! Being right on the seafront it is a bit exposed!
I have the same trouble, 3 of my bags have met the 'storms doom', luckly they are just about ready, but I would've been gutted if it had happened before now.
My peas also took a battering, the pods were just coming on and starting to fill up.
If the haulms are very badly damaged it's very difficult for them to recover. It happened to me last year and I don't think the spuds bulked up much at all after that, even though they got a high potash feed. Don't give up on them yet, though.
They may come back yet.. I always worry during a good storm
My potatos are still standing but 2 broadbeans also broke their stems while my cucumbers are withering in the cold rain. Seriously missing flaming June...
Know how you feel but most of the spud is underground-you may have to harvest earlier than you planned just use them as extra early spuds-yum!
