yellow spotting on rose bush leaves
I really don't kill all plants! My rose bushes are now getting yellow spots on leaves. Before this gets worse, I would like some help, please! How can I fix?
Yellow spots could be fungus starting to attack. Spraying them with a fungicide such as Green Cure would be a good thing to do. Turn the leaves over and make sure nothing is munching on the backside. If you find some little bugs or worms, then spray with an insecticide or get some Bayer Tree and Shrub granules, apply per the label for ornamentals. Once scratched into the soils, water in well.
