Can I spray OVER THE TOP II over the top of my breaded Iris without damage to them?
Ferti-lome Over the Top II Grass Killer is a post-emergent selective herbicide that kills annual and perennial grasses in ornamental landscapes and desirable plants. Iris plants are tolerable per the product label. You will use 1 fl. oz. per gallon of water and add a surfactant such as Hi-Yield Spreader Sticker.
