How old are too old potatoes?

Hi all,

I planted potatoes this year, I cant remember what variety but they were not earlys. Due to bad weather and lack of light in the evenings I have still not dug them up.

They were due to be dug up when I harvested my pumpkins which seems like decades ago now.

Will they be safe to eat if I dig them up in the next couple of weeks, if of course they are not rotten?

Any advice would be greatly received.

Thanks, arugula.

I know it seemed like a bit of a dumb question but I'm not really experienced with potatoes.

Thanks again  :happy:

Unfortunately I still have a whole bed of spuds still in,goodness knows when I will get to dig them up,sure they will be rotted after all this rain. Never,never left them in in 30 years of gardening but then again I've rarely had that many planted before,been trying to clear the ground-unsuccessfully as it turned out.
