  • What’s wrong with white rose leaves?

    Created by Donna Kay on June 16, 2016 at 10:16 am

    My white rose bush’s leaves are deformed and don’t open completely. It’s several years old and used to have full healthy leaves and was covered in flowers.

    Hi Donna –

    Small, crinkled or deformed rose leaves are often the result of powdery mildew disease. Look for raised blisters on young leaves that cause them to curl and expose the lower surface. This common fungal problem will make plants and flowers look like they’ve been treated to an after-bath dousing of talcum powder, I’ve included a link to our Powdery Mildew Treatment and Control page.

    Hope it helps!
