Brian from Louisville Kentucky writes
We would not recommend Tenacity Herbicide be applied to flower beds and ornamental plants. According to the product label: “Avoid over-spray or drift of spray applications onto ornamentals or flower beds and gardens. Roses and daylilies are sensitive plant species. Avoid applications over the top of exposed roots of trees and ornamentals." A product that can safely be applied to Liriope, landscaped areas, over the top of ornamentals is Fusilade II Herbicide.
