Water: Palm-leaf marshmallow thrives in moderate climates, preferring consistent moisture and weekly watering to keep the soil evenly moist. While it can tolerate short dry spells, optimal growth and lush foliage occur with regular hydration during its active growing season.

Fertilize: To care for palm-leaf marshmallow, use balanced fertilizers with high phosphorus during blooming, applying every 4-6 weeks in growing seasons and less in winter. Avoid over-fertilization to prevent nutrient burn. Water thoroughly after fertilizing to promote nutrient absorption and protect roots.

Pruning: Palm-leaf marshmallow features tall growth and lobed leaves. Prune in early to late spring to remove dead wood, thin overcrowded stems, and shape for air circulation. This rejuvenates the plant, boosts blooming, reduces pests, and enhances overall health and aesthetics.

Propagation: Palm-leaf marshmallow propagates well via sowing. Apply cold stratification to seeds for dormancy breakage. Use well-draining soil and maintain consistent moisture, avoiding waterlogging. Provide bright indirect light for germination. Once seedlings are strong, transplant carefully, ensuring adequate space for foliage growth.
