If you carefully dig and pot them once you're confident they are well-rooted, they'll be mobile enough to move in or out of protected environs as necessary when winter comes. If you have an unheated, insulated garage you might keep them there during the worst weather, or you could bury the plants on their sides in the garden until spring. The latter method is very easy and relatively foolproof, but I recommend finding a spot with good drainage for this purpose. Good luck!

Stefanb8,
Thank you for your response.
I am so amazed at the process of progration.
I have tried the baggie method and the jug method and at last something seems to have worked for me.

I am going take your suggestion and, when the time comes, I am going to bury them until the spring.
