A colleague told me that in a region where all tree removal required consent he had processed many consents for removing lemon trees and concluded they (and limes) are particularly bad at damaging concrete paths and foundations.
This is of particular interest to me since just a few months ago I planted a lemon tree not much more than 1m from the concrete foundation of our house. I don't have a lot of space so it makes sense to keep things tightly spaced, and I was intending to keep it heavily pruned.
We have a 600mm eave and it's usually quite dry under it, so towards the house is probably an undesirable direction for the roots to grow.
Can anyone confirm whether lemon trees are any worse at damaging concrete than other trees?
