Stephanie from Tustin, Ca writes
After spraying our grass, my roses show stress and droop. Is it possible that over spray has harmed them? If so, can this be reversed?
The Turflon Ester label does not state any precautionary instructions for roses, but does advise, " Very small quantities of spray, which may not be visible, may seriously injure susceptible plants. Do not spray when wind is blowing toward susceptible crops or ornamental plants that are near enough to be injured. Spray drift can be reduced by keeping the spray boom as low as possible; by using higher volume sprays and lower pressures; using nozzles that deliver larger spray droplets; and by spraying when wind velocity is low." We recommend contacting your local Master Gardener for help and recommendations on what products to you use and when the best time fram for treatment is to help reverse any damage done.
