Pot up young seedlings as soon as they are large enough to handle, keep them wet by standing the pots in shallow water and overwinter for the first year in a greenhouse or cold frame. Division in spring just before growth starts[19]. Very easy, the plants can be divided at any time in the growing season and can be planted direct into their permanent positions[K].
