Curling leaves

10 years ago

Anyone know what causes this? How do I fix it? This is the first year it has happened to my roses. It only affects 2 bushes that are next to each other in the garden. The others seem to be fine.

Are they getting enough water?

Agree with 'kentucky_rose' as a preliminary diagnosis based on photo (I'd much rather be doing it in person)

Curling of the leaf edges is one of the early signs of powdery mildew infection.

What variety is this? Some varieties are more resistant than others.

Are you using a fungicide? Which one? Also some information on your cultural practices like watering and mulching would be helpful

If you are already using a fungicide labeled for PM, it may be that you have encountered a resistant strain of the fungus. PMs are notorious for developing strains that are resistant to certain fungicides.

I know I raised more issues for you than I settled, but I'd be hesitant to go further without knowing these.
