Oleander Plant Care

Oleander (Nerium oleander) belongs to the Apocynaceae family within the Nerium genus. Oleander is native to Mediterranean region, Africa, southern Europe, South East Asia. Oleander is also known as Rose Bay, Rose Laurel, Rosebay.

Oleander displays an upright, bushy growth habit, reaching up to 10 inches tall with a spread of approximately 8 inches. Oleander produces showy, five-petaled, funnel-shaped bloom that comes in various colors, such as pink, white, red, or yellow.

Leaf size: approximately 3 inches.

Nerium oleander requires watering every 7–14 days. Allow the top layer of soil to dry between waterings to prevent root rot. Reduce watering frequency during winter when growth slows.

Oleander thrives in full sun light conditions. The optimal light range is 2000–5000 lux. Avoid placing Oleander in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Nerium oleander grows best at temperatures between 50°F and 90°F. Oleander prefers humidity levels of 40–60%.

Well-draining soil mix. Good drainage is essential for Oleander to prevent waterlogging, which leads to root rot and fungal issues.

Repot every 2-3 years in early spring. Choose a pot one size larger than the current container, and ensure it has drainage holes to allow excess water to escape.

Oleander can be propagated through stem cuttings or seeds.

Oleander is susceptible to aphids, scale insects, spider mites. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Oleander grows outdoors in USDA Zone 8b – 11b. Native to Mediterranean region, Africa, southern Europe, South East Asia, Oleander is adapted to warm climates. In cooler regions, grow Oleander as a houseplant or bring it indoors before the first frost.
