“Nerium Oleander” is a very hardy, vigorous growing, large shrub in the subtropics and makes an excellent screening plant.
They are low maintenance and drought tolerant growing up to 3-4 metres. They benefit from a good trim and fertilise at the start of Spring each year to keep them thick and bushy.
We grow Oleander onsite here at Ross Evans in Red, White or Pink.
Oleander thrives in full sun, so choose a location that receives at least 6-8 hours of direct sunlight daily. It can tolerate partial shade but may flower less profusely. Oleanders are versatile and can be grown in garden beds, used as hedges, or even planted in large containers. Ensure the planting site is well-drained and in an area with good air circulation to prevent fungal issues.
Oleanders prefer warm, Mediterranean-style climates and grow best in temperatures between 15°C and 35°C. They are highly drought-tolerant once established, making them a good choice for dry regions. However, they are also tolerant of coastal conditions and salt spray, which makes them ideal for seaside gardens. In cooler climates, consider planting them in a sheltered spot.
Oleander is adaptable to a wide range of soils but performs best in well-draining sandy or loamy soil. It can tolerate slightly alkaline soil and poor soil conditions but avoid heavy clay or waterlogged soils, as these can lead to root rot. Amending the soil with compost can improve growth, especially in poorer soils.
Feed oleander with a balanced, slow-release fertiliser in early spring to encourage healthy growth and prolific flowering. An additional application in mid-summer can help extend the blooming period. Organic options, such as compost or well-rotted manure, are also beneficial for overall soil health.
Oleanders are drought-tolerant but benefit from regular watering, especially during their first few years. Water deeply every 1-2 weeks in dry conditions to encourage strong root growth. Once established, they require minimal watering but will appreciate occasional deep watering during extended dry spells.
Prune in late winter or early spring to remove dead or damaged branches. Regular trimming helps control size, encourages bushier growth, and promotes more abundant blooms. Oleanders tolerate heavy pruning if they become too large or unruly.
Check for common pests such as aphids, scale, and spider mites. Treat infestations early with neem oil or insecticidal soap. Oleanders are generally hardy but may develop fungal issues in areas with poor airflow—ensuring proper spacing helps prevent disease.
