I plant mine in a Potato bag any time July and August depending when you get them.

Most people were disappointed last year. Wouldnt try them again, expensive mistake. Might be ok in the polytunnel, just dont know.

We found them a waste of time and money the one year we tried them.

Nothing Snoop in my opinion, I think it is just a novelty

If you're growing spuds anyway this year, why not leave some in, for a very late digging. The times I've found perfect 'new' pots when I've been turning the ground in winter, you might try leaving some in situ for a very late harvest

Guess it depends if you get a serious frost before Christmas Worthy. Though, having said that, we once gleaned desiree tatties in January which had been frozen and they were wonderfully flavoursome!

Actually I only grow one bag at this time of year and down here the frosts are not so severe before I harvest them but being in a bag they can be moved if need be.

Snoop, who needs mash whet there's roasties...

To soak up the gravy :-) Mind I only do roast for Bulba and self

You can soak it up with roasties if you squash them hard enough.
Steveg I found one of my earlies that had been living for a few days in a lidded terracotta potato storage pot had started to grow already so it might well be worth giving it a try.
