|2 weeks ago my husband sprayed weed and feed on all myknockout roses and impaitients. Now everything looks like its dying is there any hope?|
It all depends on how much of the product was used and how much of the plants foliage or root system was contacted. The impatiens will not likely survive but the roses being a woody species might make it. Your best bet it to wait and see. There is nothing you can do to remedy the product now but there is some small chance that after some time next spring the plants will recover and gradually resume normal growth. If you want faster results you'll need to replace the plants.
