Bindweed is known as "the devil's weed" here in Virginia. I dont know
how much you have, but I have used this technique with poison ivy. Any
weed killer full strength in a glass bottle. Place end of weed in bottle
and the weed will suck up the solution and die back roots and all. This
was before roundup etc, so I'm sure that it will go much faster. Re:
poast. I'm assuming that this will work on all perennials, e.g. mums
and vinca. I'm the only gardner in the neighborhood and my beds are
continually invaded by goose grass and all other nasties from my
non-gardening and non-working neighbors. A while back someone mentioned
using Preen as a deterent. Last summer I transplanted iris to virgin
former lawn area. The neighborhood hardware was going out of business
and was selling a big box for 2.00. I figure what the heck. Comparing
iris beds this spring the new bed had about 10 % of the weeds as the
older beds and this was at the edges.
