Soil Type

Water: Seaside daisy thrives in coastal conditions, requiring minimal supplemental watering due to its adaptation to moist air. It prefers moderate humidity and tolerates brief dry spells. Regular weekly hydration helps maintain vigor, with natural rainfall patterns assisting during wetter seasons.

Fertilize: Seaside daisy thrives with balanced fertilizers during the growing season, transitioning to high-phosphorus formulas for blooming. Monthly applications using a diluted quarter-strength solution are ideal, adjusting in winter. To enhance vitality and flowering, fertilize on moist soil near the drip line for optimal nutrient absorption.

Pruning: Seaside daisy thrives in coastal gardens and requires pruning from early spring to late winter. Trim faded blooms and leggy growth for compact shape and air circulation. Regular dead stem removal boosts health and encourages vigorous, continuous blooming.

Propagation: Seaside daisy thrives in coastal areas, particularly along the western North American coastline. For best results, divide established plants during their active growth phase. Ensure each division has a healthy root system and adequate top growth. Maintain similar soil moisture and light conditions for successful establishment.

Repotting: For seaside daisy, a coastal perennial, repot every 2-3 years in spring using a slightly larger pot. Provide well-draining soil and consistent watering while avoiding waterlogged conditions to support its mounding growth and resilience.
