I'm so sorry for you. Hope they recover.

Marie in ME

I feel your pain BorS. I too have had mildew--this year most notably on Perle d'Azur, addisonii, glaucophylla, and the trio of mildew magnets--Gravetye Beauty, Princess Diana, and Etoile Rose. The last three have been cut to the ground and I am awaiting regrowth which will immediately be sprayed with fungicide. Pagoda has a little mildew but nothing drastic. Roguchi and Arabella which have had mildew in the past have none yet this seasaon.

I too have noticed that the type IIIs have the worse problems with mildew. My type IIs don't but I have horrible problems with severe brown out with them. Right now Piilu, Ramona, HF Young, and the President have come down with the browned out syndrome. They just don't like the southern sun regardless of how much water you supply.

My Roguchi has always been the only clematis in my yard to get mildew. This year the 2 clematis next to Ruguchi have it now, those being Prince Charles and Ville de Lyon. I think this is the last year for Roguchi for me. It is just a mildew magnet and now it is spreading it to other clematis around it. I don't spray, it's too much bother. I think if I get rid of Roguchi my other clems will be ok next year. I have Arabella and Betty Corning also.
Those have never had mildew on them for me so far. I hope yours recover. Karen

I'm not spraying. I'm cutting Arabella and Barbara Harrington down as they are mildewed the entire way and pruning off the mildewed sections of Betty Corning. I think I'm wrong about Princess Diana, I think it is Betty growing through her.

Karen, in the past when Roguchi got mildew, Arabella planted next to it also got it. This year both are free, so far, of the stuff. If I could only say the same for the terrible trio I related earlier- Gravetye Beauty, Princess Diana, and Etoile Rose.
