Why Won't My White Oleander Bloom?

Updated November 21, 2016

Oleanders are large shrubs that produce showy, white blooms. Oleanders are generally easy to care for when properly planted. When an oleander fails to bloom, it typically means a planting problem.


Oleanders prefer full sun conditions, with exposure to six to eight hours of sun per day. Inadequate amounts of sun contribute to decreased or no blooming on otherwise healthy oleanders.


Oleanders, like other shrubs, grow into a hedge-like structure when planted close together. While hedges form ideal windbreaks, excessive wind exposure can damage flowers and buds, contributing to less than normal blooming, according to the International Oleander Society.


The oleander tolerates drought conditions once it is properly established. While drought will not kill a plant, many drought-exposed plants fail to bloom. Water oleanders at a rate of about 1 to 2 inches per week to encourage blooming after a drought.
