Rick,
You don't know how lucky you are not to have bindweed (=wild morning
glory)! (Of course, I don't have to construct a Maginot Line to keep
gophers out of my iris beds, so I guess each of us has our own problems to
deal with).
Poast is a grass-specific herbicide. That is why you can spray it over the
top of other plants without ill effect. It has no effect on broad-leaved
weeds like bindweed. Roundup is the only thing I have found to be effective
with bindweed, but it has to be applied repeatedly at the highest
recommended concentration and at the proper growth stage (late summer-early
fall seems to work best here). And, of course, it has to be applied
judiciously if you are spraying among the iris rows or beds to avoid drift
getting on the iris. If you are in a really tight spot, you can apply the
Roundup to the target plants with a paint brush and avoid spraying
altogether.
Established iris are not killed by Roundup drift, but quite often the
flowers the following bloom season will be distorted, having the cupped
form somewhat resembling a tulip and a thick waxy substance to the petals.
