Water: New Zealand bottlebrush, native to New Zealand, thrives in high humidity and prefers evenly moist, well-drained soil. Watering should occur every 1-2 weeks, ideally using rainwater during growth season to meet hydration needs without overwatering.

Fertilize: For new Zealand bottlebrush, apply balanced nutrition fertilizers bimonthly during spring to summer, reducing frequency in fall and ceasing in winter. Water the soil before application and avoid over-fertilization. Young plants may need more frequent feedings for growth. Adjust based on seasonal variations and plant response.

Pruning: New Zealand bottlebrush features striking crimson flower spikes and requires pruning in early to late winter, avoiding its flowering period. This practice promotes air circulation and minimizes disease risk, while clean tools prevent infections. Dormant season pruning encourages strong spring growth.

Propagation: New Zealand bottlebrush originates from New Zealand and requires stratification for successful seed germination. Sow in well-draining soil, keeping moisture consistent but avoiding overwatering to prevent rot. Early growth thrives in indirect light. Once established, seedlings can be transplanted to allow for proper maturation.

Repotting: Repot new Zealand bottlebrush every 2-3 years in spring using a large, deep pot and well-draining soil. Place in bright, indirect light and minimize disruption during repotting. Regular watering aids recovery, but avoid waterlogging to support the growth of its characteristic red blooms.
