Cultivation details

Succeeds in full sun in a well-drained fertile preferably alkaline soil[200]. Prefers a heavy soil[16]. Succeeds in any reasonable soil. Succeeds in maritime gardens[200]. Tolerates a pH in the range 4.3 to 8.3. Jersey kale is a very tall-growing plant, usually reaching about 1.5 metres tall though it has been seen more than 5 metres tall[200]. The large leaves can be cooked as greens whilst the straight slender stems can be dried and used as walking sticks[200]. A good companion for celery and other aromatic plants since these seem to reduce insect predations[18, 20]. Grows badly with potatoes, beet and onions[20]. Grows well with potatoes, beet and onions according to another report[201].

Plant Propagation

Seed - sow in a seedbed outdoors in April. Plant out in summer as space allows. Do not let the seedlings get overcrowded or they will soon become leggy and will not make such good plants. If your seedlings do get leggy, it is possible to plant them rather deeper into the soil - the buried stems will soon form roots and the plant will be better supported.
