If they are main crop so longs you lift them before frost thy should be okay but you may find slugs have been eating them.

Cheers ;-))

We haven't lifted our yet and probably won't for another month approx.

Mine are getting sluggy already.

Mine are in pots would this make any diffrance ?

Rather depends if you have pot climbing slugs....You can always grope about in the compost and get a potato out to look if its OK. But assuming that you aren't growing main crop its probably time they were ready anyway. I just dig ours as I want to cook them.

I've no slugs at all where my potatoes are, but I have quite a lot and they're second earlies. The tops have gone altogether but the spuds are fine so far.
