What with the cool temperatures and sporadic rain, I can stop complaining about aphids and move on to grousing about powdery mildew on those new roses. At first, I thought a couple of them just weren’t getting enough sun, but now I realize it’s the weather. This too shall pass, but at the moment those curling leaves and that suspicious white film creeping over the leaves is enough to curdle my insides. The back garden’s mature roses, however, WOW! Take a look: (That’s a variegated leaf weigela behind the rose)
