Water: Snowy sunflower thrives in arid conditions, showcasing exceptional drought tolerance and low humidity preferences. Watering twice a week suits its minimal needs. Adapted for xeric landscapes, snowy sunflower is ideal for dry climates, emphasizing water conservation due to infrequent rainfall.

Fertilize: For snowy sunflower, use a balanced fertilizer (10-10-10) every 6-8 weeks during the growing season, reducing in winter. Apply 1 lb per 100 sq ft, adjusting for potted plants, and consider slow-release options. Monitor snowy sunflower's response to adjust fertilization schedule accordingly.

Pruning: Snowy sunflower features silvery leaves and yellow blooms, thriving with regular pruning. Key methods involve trimming dead stems and shaping for airflow. Best done in early to late spring, these practices enhance flowering, prevent legginess, and promote a fuller growth habit.

Propagation: Snowy sunflower can be multiplied by sowing seeds in well-draining soil, lightly covering them for germination. Maintain consistent moisture using a fine mist. Once seedlings are sturdy, transplant into individual pots or final locations with full sunlight and ample space.
