I have had Shocking Blue in two very different climates. I have not had a powdery mildew problem in either place. Blackspot is a different matter. That I have had in both places.

How big of a root ball and was it intact or broken? A short conifer such as this should not have taken a tilt in high wind if the root ball was substantial enough to anchor it in the ground. The needle drop is from stress and probably not enough root mass to support topside foliage. I see browning out midway up the plant which is not a good thing. There is a good chance this plant won't be a survivor. A good rule of thumb is never by plants that have been sitting around all Summer especially if root B&B. It was probably dead when you planted it. Buy early ,March/April, when planting B&B. Save your warrantry and replace next Spring. Dave

I've always considered G. wallichianum to be more sun/heat tolerant than most other Geraniums. I know up here, for example, Geranium 'Rozanne' (which has G. wallichianum as a parent), prefers full sun. I would suggest trying to position your new 'Shocking Blue' in a similar environment as your 'Rozanne' and go from there.

I just finished my bathroom after an eternal search for the right blue/green spa-like color. I tried about 7 different colors and I'm thrilled with the outcome. I used Para Paints "On a Cloudy Day" P5166-24. Benjamin Moore made the paint for me. The result is a soft color that reminds me of the ocean. I found Ocean Air which I originally loved to be fairly bright when I tried it out on the wall. These pictures are taken in a very sunny day so it looks a bit lighter but I think you'll get the idea.
