We had been trying to identify a tree growing (very fast!) right next to
the wall of our daughter's new house --- and ailanthus it almost
certainly is! They have only been in the house a couple of months, and
in that time it has grown to some 3m.
I had not knowingly seen one before, but we're pretty sure. In any case,
whatever it is, it has to go. If anyone has successfully eradicated an
ailanthus, could you tell us how?
And as the house was surveyed just three months ago, surely the surveyor
should have warned them!
Thanks!
