Water: Polyalthia thrives in tropical rainforest conditions, favoring humidity and balanced moisture. It is drought-tolerant, needing watering every 2-3 weeks. As an evergreen, polyalthia retains water in its leaves, making it suitable for indoor environments with controlled humidity.

Fertilize: Fertilizing polyalthia supports vigorous growth. Use balanced fertilizers, shifting to high-nitrogen types in the growing season. Apply quarterly, with caution for young plants. Water polyalthia before fertilization to prevent root burn. Adjust frequency based on seasonal growth, reducing in winter.

Pruning: Polyalthia is an evergreen shrub or small tree with glossy leaves and fragrant flowers. Prune in early to late winter, removing dead wood and overcrowded branches for better air circulation and shape. Use sterile tools to promote healthy growth and enhance ornamental appeal.

Propagation: Polyalthia is effectively propagated through cuttings, using 4-6 inch healthy stems. Plant in well-draining soil with high humidity and indirect sunlight. While rooting hormone can aid success, it’s not essential. Maintain consistently moist soil for optimal root development.
