How to Use

• Step 1: Before each OH2 Ornamental Herbicide application, remove any existing weeds with a post-emergent herbicide. Determine how much OH2 Ornamental Herbicide to use by measuring the square footage of the treatment area. To do this, measure the length and width of the treatment area in feet then multiply them together (length X width = square footage). For acreage, take the square footage and divide it by one acre (square footage / 43,560 sq. ft. = acres). For individual ornamental container applications the rates will vary based on container size and surface area. To treat 1 gallon containers (6” diam.) with a 0.20 sq. ft. surface area use 1/8 tsp. of OH2 Ornamental Herbicide. For 2 gallon (9” diam.) containers with 0.44 sq. ft. surface area use 1/4 tsp of product. For 3 gallon containers (10" diam.) with a 0.55 sq. ft. surface area use 1/4 tsp. of product. For 5 gallon containers (12" diam.) with 0.79 sq. ft. surface area use 1/4 tsp. of product. For 15 gallon containers (17" diam.) with 1.60 sq. ft. surface area use 1/2 tsp. of product. For field grown ornamentals, apply 2.3 lbs. of product per 1,000 sq. ft.
• Step 2: Load the measured amount of OH2 Ornamental Herbicide into the properly calibrated spreader.
• Step 3: Spread the OH2 Ornamental Herbicide across dry foliage as an over the top or soil directed application. Water in with 1/2-1 inches of irrigation immediately after application to wash the particles off the plant foliage and to activate the herbicide.
