How to grow Agapanthus 'Donau' in NZ

Plenty of sunlight encourages vigorous growth, healthy foliage, and abundant flowering throughout the season.

Agapanthus 'Donau' care tips

Agapanthus 'Donau' is a low maintenance perennial that requires very little ongoing care. Remove spent flower stems after flowering to keep the plant tidy and direct energy back into growth. Apply a balanced fertiliser during spring to support healthy foliage and prolific blooms. Water during extended dry periods, particularly in warmer regions. Dividing mature clumps every few years helps maintain vigour, reduce overcrowding, and encourage continued flowering performance.
