Celero Herbicide cannot be applied over-the-top, around or within root zones to desirable flowers, ornamentals, vegetables, shrubs or trees per the product label. We would recommend contacting a local Arborist or the Master Gardner Division with your County Extension Office for their recommendations on active ingredients/products specific to the weeds you are treating and varieties of trees on the tree farm.
