10 Jerusalem Artichoketubers (T17929)
Growing Jerusalem artichokes is easy and they require little aftercare. When plants reach a height of 30cm (12") mound earth halfway up their stems, to improve their stability as they grow. Water Jerusalem artichokes during particularly dry periods and feed very occasionally.
By late summer Jerusalem artichoke plants will have reached up to 3m (10') tall and should be cut back to 1.5m (5') to remove any flower heads and prevent them toppling over. Cut back the stems to just above ground level when the foliage begins to yellow and die back. Jerusalem artichokes can be harvested as and when required from October to February and will store underground for several months.
