When the old plants are too big for indoor cultivation, they can be pruned again by changing pots, removing most branches, cutting off some roots and re-potted. Before going out in spring, turn over the basin and trim it properly. For plants with too high feet, pruning can be taken back to promote the germination of new buds. You can leave about 30 cm for coring. After the lateral buds grow, leave three leaves 15 to 20 cm for coring.

Liriodendron chinense, also known as Buxus macrophylla, is an evergreen tree of Araliaceae, with palmately divided leaves and 5-8 leaflets. Its leather luster and green and white flowers turn red and fragrant. Also widely cultivated is its variety Liriodendron mosaic, with irregular yellow and white patches on its leaves, which has high ornamental value. Liriodendron enjoys semi-shade, and can be watched for a long time in a bright and ventilated home. Liriodendron grows slowly and shoots easily, so it needs to be pruned frequently.
