Tree roots cracking wall

i have two very beautiful palms growing in a retaining wall and one of them is very close to the wall and causing it to crack,  it's a breeze block wall that has been rendered and is only two years old but a block shaped crack is appearing in the render. I don't want to loose the tree it's beautiful it's one of those that looks like a giant pineapple. My question is how long do you think I have got if I do nothing before the wall is pushed out completely and does any one have any suggestions to slow down the process  image

    i'm assuming you not in the UK, or at least on the mainland.

    the bigger the palm gets the more the roots will spread, its only a matter of time before the wall loses it battle with gravity and comes down unfortunately.

    It's not the answer you want but as far as I can see you have two options - move the tree or move the wall image

    You're fortunate indeed to live in the SW and cultivate P.canariensis to such a stature !

    You might only be 'buying time' , but is it feasible to alter the structure of the wall ? i.e. extend further outwards . The possibility of moving something of that size would be a major problem .

    If this has happened after only 2 years I would be questioning the construction of the wall.  It should have been reinforced to support the weight of soil behind it.  If that had been done properly I wouldn't expect 2 years of root growth to have that much effect.

  • The wall can be rebuilt further away from the tree root and give it more room to spread so I expect this is what we will have to do. I suppose I knew there was no easy answer but thank you all so much for taking the time to reply to my questions.
