Helena Crossbow Herbicide would harm your hydrangeas, rhododentrons and other desirable ornamentals, flowers or plants if they were directly sprayed or contacted through spray drift. If the berry vines you wish to treat DO NOT have direct contact with the hydrangeas or rhododentrons and are NOT within the drip line of the desriable ornamentals, direct injection treatments to the vines should be fine. As advised per the product label, “Do not apply Crossbow* directly to, or otherwise permit it to come into direct contact with cotton, grapes, tobacco, vegetable crops, citrus, flowers, fruit or ornamental trees, or other desirable broadleaf plants and do not permit spray mists containing it to drift onto them.
