I followed that with interest because I gardened for a woman whose neighbor
had a yard full of bittersweet and knotweed that was encroaching on her
lawn. My employer wanted me to go to the neighbors yard and spray roundup
which I refused to do (so later when I abandoned her she did it herself).
The only solution in my opinion was to make a moat of landscape fabric and
mulch, and mow often.
On my own property, I put some rain barrels collecting water off the roof
and a drip hose to the perimeter, and I have espaliered fruit trees growing
very well near the roots of my neighbor's trees. They just need more water
on the edge, near trees, more than any other area of the garden. As long as
I water regularly they do fine. Also I have hazelnuts there, and they are
quite drought resistant, I don't even water them, just mulch them, and they
compete with the trees very well.
