Celsius WG Herbicide is only labeled to be used in warm season turfgrasses, it is not safe for ornamental plantings. Certainty Herbicide is labeled to control certain broadleaf and grassy weeds in tolerant ornamentals as stated on the product label which include monkey grass (big blue & variegated varities). A non ionic surfactant is recommended for best results. Please review the product label for weeds controlled and application rates.
