I have sent mine in pots but they just don't seem to have grown at all. They look so spindly!!! I had the same dilemma so I have sent mine home to my parents. My other plan was to put them In a bread tray and fleece over. What more can you do other than find a sheltered spot where your less likeky to get frost and snow sitting on them.
I'm beginning to regret not direct sowing. I sowed in seed trays and transplanted. I was v careful not to break the roots but I'm wondering why so spindly. They were potted up in about sept!
I put mine in pots and in the shed and keep them watered .They have survied better than in the ground .
