I have heard that you should let the plants grow as much as possible then
drench them with Round Up-in that way the weedkiller will spread into their
extensive root system.
It would be sensible to remove flowers in the course of the operation.
Round Up residues will disappear off before next year.
My experience with Round Up and couch grass is that small sections of root
do survive, so I would imagine your plot would have to be tightly monitored
in the years following treatment.-Bindweed will grow from small fragments of
root.

We have Bindweed covering most of our garden and plants, it seems
impossible to get rid of, every time we clean it from the garden it is
back (I know to try and remove the roots at the time time but it is so
well entrenched that this is proving very difficult). Is there anyway
to get rid of it or is it a case of clearing the garden completely and
restarting?!

It depends on the size of the garden, of course, but I used a broad-leaf
weedkiller where it was growing in grass, a "no lasting effects"
weedkiller where the plants growing with it didn't matter too much, and
then treated individual cases where it was entangled in things I wanted to
keep by pinching the bind weed off to "one pair of leaves showing" and
then I painted glyphosate gel onto those.

It will recur and you have to be persistent, but my system means that I
now only have a few areas that still need attention from time to time.
