Per the label, Grass Out Max (Clethodim Herbicide) only kills grasses and does not affect flowers, shrubs, broadleaf crops or other broadleaf plants. Since only Iris and Azalaes are listed as tolerant ornamentals on the product label, we would suggest doing a small test application around other plants not listed as tolerant on the product label.
