American Brand Herbicide Granules Containing Treflan Is A PreEmergent Herbicide For Use In Vegetable and Flower Gardens And Around Trees And Shrubs. Stops weeds and grass from growing. Eliminates back-breaking hand weeding. Apply Treflan around most annual flowers after they have been established. Many vegetables including peppers and tomatoes must be transplanted before applying Treflan. Apply as early as possible in the growing season (around early April in the upper MidWest). For garden application till the soil first. Sprinkle like salt on soil surface at the rate of 1 oz. per 10 sq. ft. Mix into the soil at 1" to 3" deep. Make a second application mid June. Do not use on ground covers. Keep children and pets out of the area until the Treflan has been mixed with the soil. 1 Lb.
