When Does Nerium Oleander Flower?

Oleanders flower from early summer until mid-autumn with large clusters of 2-inch single or double blossoms. Colors range from pure white through pale-yellow, peach, salmon and pink to deep burgundy red. Some varieties (mostly doubles) are fragrant.

What month do oleanders flower?

Flowering occurs in late summer (July to October) on new shoots of the current season's growth, so prune in late winter or early spring. Gloves should be worn when pruning as the sap is potentially harmful.

How do I get my oleander to flower?

Oleander flowers bloom on new growth, so when pruning leave enough new growth to allow buds to develop. Cut just above the leaf nodes. Prune off small suckers and broken or dead branches. For mature shrubs that will not bloom, cut back to 1/3 to stimulate vigorous growth on the branches.
