Potatoes

Hello, I have seed potatoes ready for chitting as I do every year.  But this year (2021) for the first time some but not all, have imploded and I have been told they are fermenting.  Can anyone advise on this as this has never happened before?  Thank you.

Welcome!

What variety are they? I know that there have been issues with Lady Christl this year which is why few suppliers were able to deliver the orders.

Another thought is could they have frozen at some point eg: where they delivered in the snowy spell that some of us had.
