I sprinkled Merit granules around petunias now they look sick.
Merit 0.5 G Insecticide is labeled for use around flowers at a rate of 1.4 – 1.8 lbs per 1000 sq ft. Since this is just an insecticide, then it typically does not cause issues around flowers. If the granules were watered in very heavily, then that could encourage disease development around ornamental plants, but otherwise you may need to speak to a master gardener for assistance with any issues concerning your flowers.
