Hi
I dug mine up about a week and a half ago.
I took a peak at the months weather and noticed that we are still in for lots of wet weather and I could see lots of slug eggs around my potatoes.
Also, I didn't fancy digging up potatoes for tea on a wet day, kids in the car and trudging back covered in mud and a foot higher with mud under my boots!
I laid down a picnic rug in my shed and dried all of my potatoes and checked them twice to make sure the ones I was storing were slug, wire worm and damage free.
I kept a few hen egg sized potatoes for next years seeds and am working my way through the remainder that are damaged on my picnic rug (for mashed pots or roast pots) - shed also has had windows blacked out so no sun can ruin the potatoes.
Also worth mentioning, if you leave potatoes in the soil during frosts, they are meant to turn them sweeter.
So that is why I have dug up and stored my potatoes now.
I have been told that you should check them around January time and turf out any bad ones and just keep a closer eye on them from January onwards.
I hope that helped!
Good luck!
