Thirsty Trees

Post by Rampage »

We have a couple of mature Mimosa tress and one other type that I don't know the name of (bronze coloured leaves/blossom ar the end of green leafed branches) in our back garden in CVO. They are beautiful trees but unfortunately roots from one or all of them regularly invade the underground drainage pipes from the villa and cause blockages. The agent has a machine on call that quickly clears the system but I am afraid that the damage could become more permanent and start to impact on the building foundations.

Does anyone know a tree expert in the area who could advise the best way to deal with this problem? I am loath to uproot healthy trees if at all possible so a selective surgery or removal may be the best option. However, some expert advice is needed.

You will find that most of the trees in the Algarve (and other dry climates) have a wide rather than deep root system which will always become a problem to infra-structure after a few years (Palm trees are the worst) as they tend to spread towards house and pool installations clogging up the pipes.

The only permanent solution, if these trees are too close to the house or the pool, is to uproot them. Alternatively, you can cut off the roots growing in the direction of the house, but that may well kill the tree aswell.

The second issue as the trees grow older will be the strength of the roots. These roots can cause serious damage to terraces and pools and ultimately will start to affect the structure of the house if they get too close.

No matter what you do, as long as the trees are left standing close to the house the roots will always find a way in.
