Sounds as if you can risk leaving your tubers in overwinter, lifting and dividing every 3 or 4 years. Break off as many tuber pieces with eyes as you need and pot up. Any old container will do. All the food is in the tuber, you just need to keep any foliage fresh with little water. Pinch for bushiness and plant out towards end of May, when fear of frost is over. Keep pots outside if mild, whip inside if frosty.
