Just remembered that HomeBase were selling plant pots with potato plants in.
They looked like about 10" pots.

So - some questions that have occured to me since.

Can you grow potatoes on in pots and transplant outside later?

Is this a way of starting potatoes off to transplant into tubs without all
the problems of gettting them started at the bottom of the tubs in poor
light before gradually earthing up, or having a tub which is built up slowly
as the potato plant grows?

Or can you get enough potatoes in a 10" pot to make this worthwhile?

Cheers
