Soil Type

Water: Island mallow thrives in coastal regions with consistent moisture, preferring moderate hydration. It requires weekly watering to mimic its natural habitat. As an evergreen, island mallow benefits from outdoor cultivation to receive rainfall, ensuring lush foliage year-round.

Fertilize: For island mallow, use a high phosphorus fertilizer to enhance bloom production. Apply a balanced, slow-release formula at one tablespoon per square foot early and mid-season, reducing as dormancy approaches. This supports robust growth and vivid blooms while avoiding over-fertilization to maintain plant health.

Pruning: Island mallow features large, glossy leaves and pinkish-purple flowers. Prune in early spring to late winter using sharp tools to remove dead branches, promoting air circulation and light penetration. This enhances ornamental value and supports healthier growth and flowering. Consult local resources for region-specific guidance.

Propagation: Island mallow is a fast-growing coastal California shrub with pink flowers. Propagate via healthy, non-flowering cuttings using rooting hormone in well-draining mix. Maintain high humidity, indirect light, and consistently moist soil. Established roots allow for successful transplantation.

Repotting: Repot island mallow every 2-3 years in spring to support its growth and enhance blooms. Use a pot slightly larger than the root ball, maintain moist soil without overwatering, and ensure adequate sunlight. Proper care during repotting is crucial for island mallow's thriving health.
