How Fast Does Cercis Occidentalis Grow?

Climate Requirements

• The western redbud occurs naturally along foothill slopes below 4,000 feet across California, Arizona and Utah. It is adapted to cold winter weather and requires temperatures to drop below 28 degrees Fahrenheit to induce blooming. Drought and coastal exposure will not affect its growth, although the latter may have an impact on the tree's blooming. It cannot tolerate high humidity for extended periods of time because the ambient moisture creates an ideal environment for gray mold, a potentially debilitating fungal infection.

Growing Conditions

• Adaptable and robust, the western redbud will tolerate a range of less-than-ideal growing conditions. It is not fussy about soil type, although whatever soil in which it is grown must be well drained. Full sun exposure is best, but it will tolerate some light afternoon shade with minimal impact to its growth rate. Although coastal exposure is not typically an issue, western redbuds should be shielded from strong or consistent salt spray because it may damage or discolor the foliage.

Care

• Little care is required to cultivate the western redbud, although some moderate attention during its first few years will help ensure its health, attractive appearance and long-term survival. Water deeply and regularly during its first summer in the ground to help promote a deep root system, then water only during periods of drought thereafter. Pruning to remove low side branches will create a more tree-like shape, although it is not necessary if a shrubbier tree is desired. Do not fertilize western redbuds because they will grow too quickly and produce weak, breakable branches.

Considerations

• Several infections and diseases may afflict western redbuds, including crown rot, root rot and gray mold. While typically not lethal, these diseases may slow the tree's growth and impact its appearance. Good cultural practices will prevent most illness in western redbud trees, although sometimes disease may occur despite all preventive measures. Removal of the affected branches will halt most early-stage disease, but more in-depth professional treatment may be necessary if the disease has advanced beyond one or two branches.
