Watering

Fertilizing

Balanced perennial feed every four weeks from spring through summer

Pruning

None required

Propagation

Propagate by seed at 16°C (61°F) in early spring or take stem cuttings from spring to summer

Growing

Under glass, grow in sharply-draining, loam-based compost (JI No2) with the addition of extra sharp sand, or use proprietary cactus compost. A position in full or slightly filtered light is preferred at all times. During active growth, water moderately and apply a low-nitrogen fertiliser once a month from March to the beginning of May and from late August to October, but cease feeding in the summer dormancy period, when water should be withheld. Feeding in the winter in UK under glass is not required owing to low daylight levels and similarly, watering should also be reduced
