Hi everyone,
I’m hoping to get some advice on a bottlebrush tree we have at our rental property. I planted it in this little garden bed in the back corner of the property about 5 years ago, it was tiny at the time and I didn’t really do my research in finding out just how big it would grow and how fast! Anyways fast forward 5 years and it’s a tree.. I’ve pruned it back a couple times now but my main concern at the moment is the root system. I don’t know how destructive their roots are but it’s planted roughly 1.5m from the back fence, which sits on a retaining wall - it’s hard to see from the pics but behind the back fence is about a 2m drop off and then there’s a footpath at the bottom between the fence and the lake.
So my question is do you think that over time the bottlebrush could cause damage to the retaining wall?
Our tenants move out soon so I’m trying to decide whether or not I should remove the plant now or if I’ll be safe to just continue pruning it.
Thanks in advance. Jess
