Pot up bottlebrush plants and grow them on in a cool, bright position until large enough to plant outside. Prior to transplanting, acclimatise them to outdoor conditions over a period of 7 to 10 days. Plant Callistemon in a sheltered position in moist, well drained, non alkaline soil in full sun. Callistemon viminalis plants are hardy down to -5°C (23°F). In particularly cold areas, bottlebrushes are best grown in a cool conservatory or planted in a patio container that can be moved to a sheltered position over winter.
Lightly prune bottlebrush shrubs in autumn after flowering. Reduce the stems to fit the available space, and remove any damaged, crossing or wayward stems. If necessary Callistemon plants will tolerate occasional hard regenerative pruning. Deadhead faded bottlebrush flowers regularly to prolong their display.
