Oleander Guide: How to Grow and Care for Nerium Oleander

Oleander (Nerium oleander) is prized for its beauty and resilience in gardens, but caution is crucial due to its highly toxic nature to humans and animals.

Oleander Plant Care

Light

Oleander thrives in full sun for prolific blooming; tolerates partial shade but may reduce flower production. Regular watering essential in bloom season.

Soil

Oleanders adapt to various soils, preferring well-drained types but tolerating sandy or clayey ones. Avoid waterlogged soil to prevent root rot.

Water

Oleanders are drought-tolerant; water deeply weekly in summer. Poor soils or drought may require more watering, but let soil dry to avoid diseases.

Temperature and Humidity

Nerium oleander thrives in hot climates, full sun, and drought, tolerating poor soils with good drainage but may suffer in very humid conditions.

Fertilizer

Oleanders thrive in poor soils with minimal feeding needs. Use slow-release fertilizer in summer for lush foliage and flowers; wear gloves due to toxic sap.

Pruning

Prune Nerium Oleander in mid-autumn after flowers fade but before new growth starts. Use caution due to toxic sap. Pruning controls pests and disease.

Overwintering

Prepare oleanders for winter: stop feeding before mid-autumn to avoid frost damage, reduce watering to prevent root rot, mulch for insulation in harsh climates.
