Hi Anita, Did you add your rose to your 'plants I have' list in Shoot. When you are logged in there will be advice to combat powdery mildew Let us know if that helps or if you need more help. Thanks Nicola

Hi Anita, Robbie on Twitter says "fungus clear, fungus fighter, rose clear or pick off & dispose of effected foliage."

And Mark adds "if the rose is very bushy with foliage, try removing some foliage to increase more air into and around the bush and spray" "fungus fighter is the best as its systemic - any new growth should be mildew free"
