What should I do about these spuds?

[whatwhatwhywhen]

Last year I planted potatoes in sacks and all was going well, but a family crisis meant they didn't get dug up. I went to empty the soil and start again this spring but last years ones were already sprouting so I left them.

The foliage died back and I read somewhere that you can store them in the ground and harvest later ... so I left them

Big mistake. They are now growing AGAIN!

Should I tip them out and see if any are salvageable or wait until this lot have grown?

They are in sacks so the sack is probably full of potatoes in various stages of growth!

were You thinking this? Or about storing them in spent compost maybe?
leave them in the ground for longer than normal rather than harvest them. Many earlies and second earlies will easily keep in the ground for two weeks past their optimum harvest date.

I’d say now they are growing again you will have to leave them, I don’t think they will be any good to eat.

I would tip them out & see.
We've got potatoe bags, don't this year, in some the foliage has died back & we haven't dug them up yet but they haven't started regrowing either.
Dig them up & see. Use/store what you can & put the rest back in the bags covered with soil for next year?

The tops will be growing using the food stored in the tubers. Once the tops are flourishing, they will start feeding back into new tubers. Depends where you are in this cycle as to whether there is anything worth eating. Tipping them out is a bit drastic, try loosening the soil and see what you find. The top layer of tubers won’t be very far down

Thanks everyone, the top foliage is really quite big and bushy so I think it's too late. I'll wait till it all dies down (probably Nov??) then empty them out and see if anything is salvageable. With three attempts in one sack it'll probably be packed full in potatoes of various stages of decay! Hopefully some will be edible! Third time lucky eh!
