Orchid Tree Problems

A member of the bean family, the orchid tree (Bauhinia spp.) is a flowering tree cultivated for its showy, orchid-like flowers. Like any plant in the garden, the orchid tree is susceptible to a host of unique problems that must be identified and treated.

Pests

Common orchid tree pests include white flies, a sap sucking white insect that appears on the underside of leaves, root nematodes, microscopic worms that live in the soil, and mealy bugs, a type of wingless, cottony white insect that causes leaf drop and stunted growth. Infestations can often by treated with predatory insects or insecticides.

Diseases

Orchid tree is susceptible to leaf spot, a disease which is caused by fungus. Leaf spot causes dots or irregular patches on the tree's leaves, sometimes causing premature leaf drop. Remove debris and fallen leaves around the tree to prevent the fungus from spreading.

Range

The orchid tree is considered invasive in some areas. The orchid tree is listed as an invasive species by The Florida Exotic Pest Plant Council, and is not recommended for the state as it can disrupt native plant life.
