I have issues with grass in Day Lilies and Iris. These are beds I do
not want to renovate.

I don't mind weeding, but the grass has me buffaloed.

Anyone have any experience using Poast herbicide in Iris or Day
Lilies?

I use it for strawberries, but have not tried a test on flowers.
Product label is no help on this.

Any help much appreciated.
