I am restoring an urban garden that has seen about 30 years of
neglect. When
I started the garden was completely covered by ivy, briars and
nettles and I
am nearly finished digging out an ash trees roots whoose base covers
5' x
5'. The soil in this garden is perfect and the aspect is south-west
and
there are two mature plum trees I can recover.
However there are neglected plots on either side of the wall that
are home
to two very nasty plants whoose roots are starting to creep under
the wall.
On one side there is bindweed and the other is Japanese knotweed.
Both are
heavily infested with said plants and the sites are effectivly
abandoned,
one site has recently been sold, the other is the subject of a
squatters
dispute.
Digging the roots out like the others looks like a fruitless task,
so I'm
trying to figure out how to eliminate bindweed & knotweed. I'm open
to
anyone's ideas or experience in controlling these plants?

I suggest that your only hope is to apply doses of glyphosate at about
three-weekly intervals until you have beaten them. But you will have
to make sure that you treat the complete patches of the weeds, and not
just the psarts which are invading your garden.
