Acer truncatum, commonly known as the Shantung Maple, is a deciduous tree native to China and Korea. It belongs to the family Sapindaceae and the genus Acer. This tree is known for its beautiful, lobed leaves that turn vibrant shades of red, orange, and yellow in the fall. It prefers temperate climates and is hardy in USDA zones 5 through 8. The Shantung Maple is a hardwood tree and can grow up to 25 feet tall.
The Shantung Maple thrives in direct bright light and requires moderate temperatures. It prefers soil that dries out partially between waterings and benefits from moderate humidity levels. Regular watering during dry periods is essential, and the tree should be protected from extreme heat and cold.
Soil
Acer truncatum prefers well-draining loamy soil with a slightly acidic to neutral pH. The soil should be rich in organic matter to support healthy growth. Good drainage is crucial to prevent root rot, so avoid waterlogged conditions.
Fertilizer
Fertilize the Shantung Maple with a balanced fertilizer, such as 10-10-10, in early spring before new growth begins. Apply the fertilizer according to the manufacturer's instructions, and avoid over-fertilizing, which can harm the tree.
Repotting
As a tree, the Shantung Maple is not typically repotted. Instead, ensure it is planted in a suitable location with enough space for its roots to spread. If grown in a container, repotting may be necessary every few years to refresh the soil and provide more room for growth.
Propagation
Propagate Acer truncatum through seeds or softwood cuttings. Collect seeds in the fall and stratify them before planting in the spring. Softwood cuttings can be taken in early summer and rooted in a well-draining soil mix under high humidity.
Pruning
Prune the Shantung Maple in late winter or early spring before new growth begins. Remove any dead, damaged, or diseased branches, and thin out crowded areas to improve air circulation. Pruning helps maintain the tree's shape and encourages healthy growth.
Toxicity
Acer truncatum is not known to be toxic to pets or humans. However, as with all plants, it is best to prevent pets and children from ingesting any part of the tree.
Additional
The Shantung Maple is a relatively low-maintenance tree that provides excellent fall color and shade. It is resistant to many pests and diseases, making it a great choice for home landscapes and urban environments.
