Weather Considerations for Bonsai Care in the United States
Bonsai trees, cherished for their miniature beauty and intricate care requirements, are deeply influenced by the climate conditions in which they reside. In the United States, the diverse weather patterns necessitate tailored care strategies to maintain the health and vitality of these delicate specimens.
Understanding Bonsai Climate Needs
Bonsai species are broadly categorized into two groups based on their climate preferences:
-
Outdoor Bonsai: Typically deciduous and evergreen trees from temperate climates, these bonsai require a period of dormancy during colder months.
-
Indoor Bonsai: Generally tropical and subtropical species that thrive in consistent, warmer temperatures and do not undergo dormancy.
