Water: Originating from East Asia, iigiri tree thrives in high humidity and prefers consistent moisture, requiring watering every 1-2 weeks. It's typically grown outdoors for its ornamental appeal and benefits from mulching to retain soil moisture and regulate root temperature.

Fertilize: Iigiri tree thrives on balanced nutrition and high nitrogen fertilizers. Apply balanced fertilizer every 4-6 weeks during the growing season, switching to high nitrogen in spring. Use 1-2 lbs per inch of trunk diameter, watering thoroughly afterward. Adjust according to growth stages and monitor for overuse symptoms.

Pruning: Iigiri tree features appealing berries and heart-shaped leaves, flourishing with early spring pruning to remove dead branches and improve air circulation. Thinning dense areas enhances structure and health, while annual pruning supports better form and fruiting. Use sharp, clean tools to avoid disease.

Propagation: The iigiri tree is propagated through cuttings by using a healthy stem planted in suitable soil. A clean cut and multiple leaf nodes enhance success. Hormone treatments aid root development, while consistent moisture and warmth are crucial for growth, resulting in genetically identical offspring.
