Celtis jessoensis

#Growth Characteristics

Celtis jessoensis is a deciduous broad-leaved tree native to Korea, Japan, and northeastern China. It grows to a height of 15 to 20 meters. Its leaves are alternate, oval or egg-shaped with pointed tips and shallow serrations along the edges. In autumn, the leaves turn yellow.

#Propagation Method

This tree primarily propagates through seeds. Fruits form between summer and autumn and turn black when ripe. Since the germination rate of seeds increases after passing through a cold winter, it is recommended to refrigerate seeds harvested in autumn and plant them the following spring.

#Cultivation Method
- Soil: It prefers well-drained and fertile soil.
- Sunlight: It thrives in areas with ample sunlight, but can also grow in partial shade.
- Watering: It requires sufficient water during the initial growth stage, but thereafter, relying on natural precipitation is sufficient. - Pruning: Proper pruning promotes healthy growth. It is typically performed in late winter.

#Uses in Gardens

The Japanese zelkova is suitable for gardens to provide shade or enhance ecological diversity. It is also popular as a landscape plant due to its beautiful yellow autumn foliage.

#Important Pests and Control Methods
- Diseases: Leaf blight may occur. If it develops, remove diseased leaves and control it using an appropriate fungicide.
- Pests: Caterpillars or aphids may appear. Inspect the tree periodically and physically remove them immediately upon discovery, or use an appropriate insecticide.
- Other Control Methods: Keep the surrounding environment clean, and use fungicides and insecticides preventively during periods when pests are likely to occur.

Through these management methods, you can cultivate a healthy Japanese zelkova (Jesoinsis).
