My house I recently moved back into has a tree in the side yard that has over-grown the small retaining wall after 10+ years. I didn't know this was going on as I was an absentee owner for a while, but now am faced with roots that have squeezed on top of the wall bricks. I'm trying to widen the retaining wall to give the tree more room, but should I try and remove the bricks? I'm a little worried that if I remove the bricks the tree will become unstable. I see one root has managed to grow out of the bricks. I will try and make the wall taller too so the roots have dirt up to the bottom of the tree.
This is a beautiful tree and I don't want to have to cut it down, but it was certainly an error to plant it in this small of an area. Bad landscaping company for not planning ahead.
Anyone have any suggestions?
