Dahlia 'Iceberg'

How to grow Dahlia ‘Iceberg’ in NZ

Plant tubers in spring after the risk of frost has passed, in full sun and fertile, free-draining soil enriched with compost. Space plants to allow airflow and reduce disease risk. Water regularly during dry spells, avoiding wetting the foliage. Feed every 3–4 weeks with a fertiliser high in potassium to promote strong flowering. Stake taller plants to keep blooms upright.
