Fertilizing
Apply liquid fertilizer every two weeks during spring and autumn, reducing to monthly applications in winter. During summer months, supplement with solid organic fertilizer for additional nutrients. Follow dosing instructions carefully as over-fertilizing can damage the tree. Feed regularly during growing season to maintain healthy growth and vibrant foliage, but reduce frequency when the tree is less active.
Placement
In temperate climates, place the tree outdoors in a wind-sheltered, semi-shaded position from May through September. During autumn and winter, move indoors to a warm spot with abundant light, maintaining temperatures between 60-75°F (16-23°C). The minimum temperature should not drop below 50°F (10°C). When inside, avoid cold drafts from windows and heating vents that can stress the tree. A south-facing window with filtered light provides ideal indoor conditions.
Pruning
New shoots should be cut back to two leaves after four leaves have developed. Maintain the tree's shape through regular pruning during the growing season, but avoid complete defoliation as this can weaken the tree. The thorny branches require careful handling during pruning. Wiring can be done year-round to shape branches, but use guy-wires when possible to avoid damage from traditional wiring methods. Be especially mindful of the thorns when working with the branches.
Repotting
Repot every 2-3 years in early spring, with older specimens requiring less frequent repotting. Use a well-draining soil mix combining equal parts Akadama, pumice, and humus. When repotting, trim roots conservatively and handle them with care to avoid damage. After repotting, place the tree in a shaded location for several weeks to recover and maintain consistent moisture levels while new roots establish.
Watering
Water thoroughly when the soil surface begins to dry, especially during summer months when water needs increase. However, avoid waterlogging as the tree is sensitive to root rot. During winter, reduce watering frequency but monitor carefully, especially if the tree is placed near heating sources. The soil should remain slightly moist but never saturated. Good drainage is essential for preventing water-related issues.
