Tectona grandis, also known as teak, can cause allergic reactions in some people, especially from its wood dust during cutting or sanding. Those sensitive may experience skin irritation or respiratory issues. To reduce exposure, wear protective gear like masks and gloves when working with teak wood.
Common problems
Young teak trees may suffer from overwatering leading to root rot. Pests like teak defoliator caterpillars can cause leaf damage. Poor drainage and low sunlight can stunt growth.
Uses
Primarily grown for its valuable hardwood used in furniture, flooring, and boat building. Also planted as a shade or ornamental tree in tropical gardens.
Notes
Teak trees can grow very tall and wide, so they need plenty of space. Pruning is rarely needed except to remove dead branches. They are sensitive to frost and cold temperatures.
