Water: Adapted to moderate climates, tree mallow prefers consistently moist soil, requiring weekly watering. Avoiding drought or waterlogging is crucial. As an outdoor plant in temperate gardens, tree mallow benefits from mulching to retain moisture and regulate soil temperature.

Fertilize: Fertilize tree mallow monthly during spring and summer using balanced fertilizers: half strength for potted, full strength for in-ground. Prevent root burn by avoiding over-fertilization. Use slow-release granules or liquid concentrates, ensuring even soil distribution and watering beforehand to enhance nutrient absorption.

Pruning: Tree mallow thrives with pruning in late spring, focusing on dead or damaged branches and thinning overcrowded areas for better air circulation. Deadheading spent flowers promotes extended blooming and healthier foliage, supporting the plant’s vigor and aesthetic appeal while aligning with its growth cycle.

Propagation: Tree mallow, a member of the Malvaceae family, is a resilient perennial that propagates well from cuttings taken during active growth. Use healthy cuttings with multiple leaf nodes, apply rooting hormone, and plant in well-draining soil, keeping consistently moist and in indirect sunlight for successful rooting.

Repotting: Repot tree mallow every 2-3 years in spring to prevent root-bound stress. Use a slightly larger pot, provide ample sunlight, and water regularly, allowing soil to dry between. Patience is essential as tree mallow acclimates to its new environment.
