Hong Kong Orchid Tree - Growing Information and Plant Care Tips


Bauhinia blakeana grows best in USDA Zone 9B – 11. This tropical tree will usually recover from brief freezes after dropping its leaves. It will grow to its full height in tropical locations; however, will likely stay shrub like when exposed to frost and/or freezing temperatures. Avoid temperatures below 30° F (-3.3°C).


In order to bloom well, Orchid Trees require full sun to partial shade.


Water newly planted trees daily to establish the root system in the surrounding soil. Since orchid trees are drought tolerant, seasonal rains will provide sufficient moisture.


Propagation is by cuttings or air-layering – there are no seeds.


Bauhinia blakeana prefer fertile, well-draining soil.


Only minimal pruning is required to maintain shape. The best time to prune is after flowering.

Hong Kong Orchid Trees - Planting Tips

Dig a hole two feet wide and two feet deep (at least twice the size of the root ball). Place the root ball in the hole.

Back fill the hole with the native soil that was removed. You can finish the hole by making the surrounding soil an inch or two recessed to form a watering basin.

Supply nutrients to the newly planted tree by adding a thin layer of compost to the tip of the soil. This will also help to conserve moisture.
