Hi, I have noticed apparent scorching on some oak trees too, I don't know if this is the same thing. I was wondering whether, as the season has been so late this year, that when the rose has put out it's young leaves (at last) whether it has been scorched by wind before the leaves have fully hardened up? We've had quite a few bouts of drying winds in the midlands and like I say some trees have had some leaf damage like this.
Plus the sun is stronger than it would have been if the growing season had started on time. Do you get my meaning?Is it just part scorching or whole leaf damage? And are your shrub roses ok? I assume they are somewhat lower than the standard and may not be in the firing line.
