How and when to plant oleander (Nerium oleander)
Nerium oleander, commonly known as oleander, is a Mediterranean evergreen shrub admired for its fragrant flowers that appear throughout the summer. It can be grown as a standalone specimen, in large containers, or as a decorative hedge. Drought-tolerant and easy to care for, oleander adds an exotic touch to gardens and terraces. For healthy growth, it is important to plant it correctly and at the right time.
When is the best time to plant oleander?
The best time to plant oleander is in spring (April–May), once the risk of frost has passed. In mild climates, it can also be planted in autumn, provided winters are not too harsh. Since oleander is sensitive to cold, in colder regions it is safer to grow it in containers that can be moved indoors during winter.
Where to plant oleander
Oleander prefers sunny, warm locations where it receives at least six hours of direct sunlight daily. The soil should be well-drained, sandy or stony, although it will also tolerate poorer soils. It is ideal for Mediterranean-style gardens and terraces. When growing in pots, use a large container with good drainage holes.
How to plant oleander step by step
- Dig a hole twice as wide as the root ball.
- Place the plant so that the top of the root ball is level with the soil surface.
- Backfill with garden soil mixed with sand to improve drainage.
- Firm the soil gently and water well after planting.
Aftercare
- Water regularly during summer, but avoid waterlogging.
- Fertilise monthly during the growing and flowering season to encourage abundant blooms.
- Lightly prune branches after flowering to maintain a compact shape.
- In colder regions, move containers indoors or protect plants with insulating materials during winter.
Summary
Oleander is best planted in spring, in a sunny, warm position with well-drained soil. In colder climates, container growing is recommended so the plant can be sheltered in winter. With correct planting and proper care, Nerium oleander will reward you with a Mediterranean feel and spectacular flowers throughout the summer.
