How to Fertilize Queensland arrowroot?
Balanced perennial feed every four weeks spring through summer growth

Queensland arrowroot · Canna edulis
Also known as: achira; tous-les-mois
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
