Been using Bayer Rose and Flower bug killer for my roses. I've got worms,
aphids and white flys. The aphids don't seem to want to go away... should I
just continue weekly administrations or more frequent? Also some of the
leaves have black areas on them? what could this be?
One more question, what is the consensus regarding watering roses? I live in
Southern Ca.
Thanks
