I have issues with grass in old day lily and iris plantings.

I have been told that Poast is safe for both. Does anyone have
experience with Poast and either flower?

I am willing to pull weed, but the grass I can't handle by hand.

It'a been years but I think there are issues with Poast and monocots
google for full or expanded label

You might get more answers at the non-binary rec.gardens

Also I don't remember that poast was terribly effective on grasses
either. It may be time to lift the plants, clean out the grass, divide
and replant.
