Hi Kurt
We struggle with the related Greater Bindweed (Calystegia sepium) here
and one very effective low effort and relatively safe (ecologically
speaking) way to deal with it among other plants is to put the
weedkiller in a bucket or other wide-based container which is unlikely
to fall over and then unwind the shoots of the bindweed and arrange them
so the tips are immersed in the poison. In a few days it translocates
down into the rhizome and eventually kills it.
In order to get it free of one's precious plants I have sometimes found
it necessary to first manually pull out a length of the rhizome as far
as some open space. One then has to wait a short while until a new
shoot tip grows before applying the poisoning treatment. I have also
found with our particular species that rhizomes in winter when the pest
goes dormant seem to be much easier to pull out without snapping and
whole plants will sometimes come out of the ground in one piece.
It is rampant in one border of mine just now and trying to make its way
into the adjacent veg. beds, so I am myself about to embark on a
killing spree. I have had to wait much longer than I wanted as we have
had so much unseasonable rain this summer so far that it has been pretty
impossible to put out buckets of weedkiller without immediately getting
them diluted. However we are now promised some normal settled conditions
at last so I am going to risk it. It will be a grat pleasure when i can
see my poor plants again!
