Watering

Moderate regular watering, avoid prolonged drought and stagnant waterlogging

Fertilizing

Balanced perennial feed every four weeks spring through summer growth

Pruning

No pruning required, deadhead flowers to prolong flowering

Propagation

Propagate by division of rhizomes in spring, or propagate by seed (sown indoors) in spring. The seed needs to be chipped or soaked in warm water for 24 hours prior to sowing

Growing

Grow in a sheltered site with full sun and water freely in dry spells; apply a balanced liquid feed monthly. In cold regions, lift the rhizomes in autumn once frost has blackened the foliage and store in barely moist compost in frost-free conditions. In areas that are frost-free, leave in situ and protect with a deep dry mulch. See canna cultivation for further information
