Blooms with Brown Edges
I have noticed this year more than any other that my white and light yellow roses tend to get some brown edges on the outer petals during the summer months. Before the blooms even open, I can see browning on the flower. Does anyone know why this happens? Could the soil be too wet? Too dry? Is something missing in the soil? Does anyone else have this problem? I do not spray and I have heavy clay soil, so drainage is not perfect. The temps have been in the 80's most of the time this summer, with a few higher and lower days.
Any help will be much appreciated.
