How to care for your Oleander

Our tips for helping it grow healthy and strong

Oleander, scientifically known as Nerium oleander, is a fascinating shrub native to the Mediterranean region. In our nursery, we appreciate it for its ability to adapt to different climatic conditions and for its generous, colorful flowering. It is a plant that brings a touch of elegance and vibrancy to any garden or outdoor space.

The right position

Oleander prefers full sun, but can also tolerate light partial shade. Make sure it receives plenty of light to ensure lush flowering.

When and how to water it

During summer, Oleander needs a deep watering every 7 days, while every 14 days is sufficient in winter. It is important to let the top 2–3 cm of soil dry out between waterings to prevent waterlogging.

Temperature and humidity

Oleander thrives in a temperature range between 10°C and 30°C, but can tolerate lows down to -5°C and highs up to 35°C. Ideal humidity is between 40% and 60%.

The right fertilizer

During the growing season, from spring to early autumn, we recommend using a balanced liquid fertilizer every 30 days. This will help the plant maintain vigorous growth and abundant flowering.

The pot and soil

For Oleander, well-drained soil is essential. A mix of sand and loamy soil is ideal for ensuring the right balance of nutrients and drainage. Make sure the pot has adequate drainage holes to prevent waterlogging.

How to propagate it

Oleander can be propagated through cuttings or seeds. Cuttings are preferable and should be taken in late spring or early summer. This method is moderately easy and will allow you to grow new plants effectively.

Our final advice

Oleander is a hardy and versatile plant, perfect for those who want a flowering garden with little effort. Remember to check the soil drainage regularly and avoid overwatering. With the right care, your Oleander will reward you with spectacular blooms.
