The Oleander is highly prized for its dense foliage, generous flowering and rapid growth. It is often planted as a hedge to protect it from view, particularly in front of houses. But beware: beneath its harmless exterior, it can cause serious damage... especially if planted too close to a drain.
Can an oleander be planted near a house?
Yes, provided it is not planted above or too close to a buried pipe. It's not so much the house that poses a problem, but the presence of underground networks nearby. Even if there's no visible problem, a simple micro-leak in a pipe (such as a poorly done glue job) can attract rootseven if the pipe is buried more than 3 metres underground.
Distance between oleanders and pipes
If you want to create an oleander hedge, it is recommended that they be spaced 2 metres apart to ensure good growth and density.
But be careful:
👉 Never plant an oleander directly over a draineven if it is deep. The roots are very powerful and attracted by moisture.
👉 In the event of a leak, even a small one, they can sink very deep and cause a blockage, or even break the pipe.
Our recommendation: maintain a lateral distance of 3 metres minimum between planting and known pipes (wastewater or rainwater).
Why are oleander roots dangerous?
The Oleander has a very active root system. Its roots :
- extend far around the plant,
- actively seek out sources of moisture,
- can penetrate small cracks in pipes,
- grow inside until they create obstructions or breaks.
What can you do if your pipes have already been affected?
In the event of a blockage :
We usehydrocleaningA high-pressure water jet that cuts and clears the roots inside the pipe. It's fast, clean and highly effective.
In the event of a broken pipe :
The solution is lining. This technique enables the pipe to be repaired from the inside, without the need for earthworks. A resin sleeve is inserted, which hardens and creates a new watertight wall inside the damaged pipe.
Some practical advice for risk-free planting
Absolutely avoid planting oleanders above or near pipes.
Maintain a distance of 3 metres between the oleander and any buried pipes.
Use root barriers if you're in any doubt about the exact location of the pipes.
Have your pipes inspected before planting, to identify sensitive areas.
Consider other plants if your garden is small or if pipes are close by: some hedges also offer density without this type of risk.

Are oleander roots dangerous for pipes?
Yes. They're very powerful and actively seek out moistureThis can lead to blockages, leaks and even breaks. This can lead to blockages, leaks and even breakages.
Can an oleander be planted over a drain?
No, we strongly advise against thiseven if the pipe is buried deep underground. In the event of a micro-leak, the roots can reach very far down into the pipes. It's better to choose another area of the garden or a less aggressive plant.
What should I do if oleander roots block a drain?
A professional should be called in for a hydrocleaningThis effective, non-destructive method uses a high-pressure water jet to eliminate the roots inside the pipe.
What if the pipe is broken by a root?
No need to break everything! Visit lining is a modern solution that enables pipes to be repaired from the inside, without digging, by fitting a resin sleeve that forms a new watertight wall.
Which plant should I choose instead of an oleander near drains?
There are many less aggressive alternatives, such as photiniathe chalef (eleagnus)or certain varieties of non-tracking bamboos. A landscape gardener can help you choose a safe, decorative hedge.
