Hi Roxette,
This has been our rainiest season for years, that didn't help my poor curled up dogwood, plus I think I actually helped kill mine. I planted him in the full sun, too..... yes, I did. I am a new gardener and I was just so happy to finally get a dogwood I didn't pay attention to the tag til after he died. My dogwood wanted to be moist not soaking wet, like our weather was, and most important of all, my dogwood wanted shade. our front yard was in complete sun. It seemed like it rained here every day, but when it wasn't raining it was baking hot. Kansas weather. So unfortunately, my poor dogwood didn't have a chance. If you have planted yours in a partial shady place and it is the pink one that is the one that needs the shade, hopefully it will come out of it. I have learned so much!
We have a Bradford Pear, now, ornamental, that LOVES the sun. he is doing great. loves the sun, and doesn't seem to mind all this ridiculas rain we keep having. Good luck with your dogwood. They are so beautiful. Hang in there this is the best site for information on any and all plant needs!
