The plant does well in full sun but can also tolerate partial shade. It can grow up to 25 meters tall, and its width is dependent on the location it is grown in.
The ideal soil type for Liquidambar orientalis Miller cultivation is well-draining, rich, and loamy soil. It is essential to ensure that the soil pH is within the range of 5.5 to 7.5. The plant can be propagated by sowing seeds or through cuttings. When planting, ensure that 2 to 3 plants are spaced about 20 feet apart to give room for spreading.
Watering Needs for Liquidambar Orientalis Miller
The plant is drought-tolerant but requires regular watering during the dry season. For newly planted trees, water at least twice a week, ensuring that the soil is moist. The plant's water requirement decreases with age, but it is still essential to keep the soil moist. It is advisable to water the tree's base and avoid watering on the foliage for plant diseases prevention.
Fertilization for Liquidambar Orientalis Miller
During the planting season, incorporate organic matter like compost, manure, or leaf mold into the soil. During the growing season, apply a balanced fertilizer with an NPK ratio of 10:10:10 to promote growth. Fertilizers containing micro-nutrients like zinc, magnesium, and iron are also essential for plant development. Apply only the recommended amount as overfertilization can lead to leaf burn and stunted growth.
Pruning of Liquidambar Orientalis Miller
Pruning is recommended to keep the tree in good shape and promote growth. The ideal time to prune is during winter when the tree is dormant. Remove dead, damaged, or diseased branches as soon as they are noticed. Pinch growing tips to encourage bushy growth and remove crossing branches. It is essential to use sharp pruning tools to prevent damage to the tree's bark.
Propagation of Liquidambar orientalis Miller
Propagating Liquidambar orientalis Miller can be done through seeds, cuttings, or grafting.
Propagation through seeds
Seeds of Liquidambar orientalis Miller can be collected from the tree when they are fully mature. The seeds should be planted in well-drained soil, and kept moist throughout the germination period. Germination of the seeds can be slow, taking up to 2 months. The seedlings can then be transplanted to their permanent location once they have grown to about 6 inches tall.
Propagation through cuttings
Propagation through cuttings can be done by taking 4-6 inch cuttings of the current season's growth during summer. The cuttings should have at least 2-3 nodes, and the leaves on the lower nodes should be removed. The cuttings should be planted in well-drained soil and kept moist. After a few weeks, roots should begin to form, and the young plants should be transplanted to their permanent location the next spring.
Propagation through grafting
Grafting is a more advanced method of propagation that involves joining a stem cutting from a desirable cultivar to an established rootstock. The rootstock should be a young plant that is compatible with the cultivar. Once the graft has healed, the plant can be transplanted to its permanent location. Grafting can be a complex process and is usually done by experienced growers or nurserymen.
