I grow my potatoes in special bags that I bought from Marshals, they have handles so are easy to move around. For the past two years I have grown Swift and Kestrel. I plant the Swift in the bags and put them in the greenhouse in March, and harvest them in May. This year I am going to try Pentland Javelin and Sarpo Mira for a change, has anyone else tried these varieties?
In answer to suemitch05's question, I believe you can move any plantlife around Europe, I have taken plants(flowers) by trailer to and from Spain without any problems when I went to live there for 5 years, but not sure about putting them in hand luggage.
