Garden Uses
- Landscape Tree: Its strong vitality and cold tolerance make it suitable for gardens in northern regions, and it is particularly well-suited for wetland landscaping.
- Screening and Windbreak: Its tall stature and dense canopy allow it to be used for screening or as a windbreak.

Important Pests and Diseases and Control Methods
