What is the term for a professional who specializes in tree care?

The term for a professional who specializes in tree care is "arborist." Arborists have in-depth knowledge about the biology and care of trees, including their health, growth, and maintenance. They are trained to handle various tasks such as tree pruning, removal, planting, and disease management, ensuring the longevity and vitality of trees in various environments.

Arborists often have certifications and training that focus specifically on tree care, making them the best choice for understanding the specific needs of trees, which can vary widely depending on species and environmental conditions. Their expertise helps to promote tree health and safety and can also involve understanding local regulations regarding tree care and protection.

The other options refer to different professions: a tree curator typically focuses on the management of trees in botanical gardens or parks, landscape architects deal with design and planning of outdoor spaces but are not specialized in tree care, and horticulturists study plants broadly including growing them, but their expertise is not limited to trees alone.
