Answer: The dried stem piece must be attached in order for the tuber to grow. A stem with several tubers attached to it will make a larger or thicker plant sooner than a partial stem with a single tuber. Sometimes, it is possible to divide a clump even further but a portion of stem must be left on each division so it can be difficult to do. When planting, plant the tuber with the stem end up.
