I'm in between zone 5 & 6 in southwestern PA. (near Oakmont, PA) The tree is planted on a flat hilltop lot. It gets nearly every minute of sunlight. It is also very windy. I looked closely at the blooms today. Many have one petal that is much smaller (underdeveloped?) than the other three. Some have two such petals. A little more history... I bought the tree in 2007 after blooming season. It had many large deep pink blooms in 2008. It grew well, however the 2009 blooms were small and the color weak. The same happened with this year's blooms.

This is July 2020. I have two "pink" dogwoods that bloomed in April, normal, but now in late July they are blooming with large beautiful "white" blooms. I understand the change in color may be due to soil PH but to bloom this late and such large blooms is welcomed. Normally these two pink dogwoods have small pink blooms, pitiful. Maybe they heard my threat, if they don't start making better blooms, they're gone. Hopefully this is also a sign that my blueberry bushes will produce more fruit next year.

Thanks Madrone - The tree sits on a bank over the sidewalk on the north side of the house. I added a sprinkler system 3 years ago, but the tree had already stopped blooming a few years prior. I did remove sod from the area around the tree and turned that area into flower beds. Because the tree stands alone and rises above the house, it seems to get plenty of sun - at least on its upper branches. Last year we had @ 6 blooms on the tree, this year none. Some years ago the tree picked up a fungus, but its been sprayed for several years now and still no blooms.

I hope they'll be okay. We had the same thing happen here last year. It was April 16th and we had a rare and unexpected freeze for that time of year. There were a lot of buds and blooms. Fortunately most plants and trees weren't adversely affected. Maybe you will be as fortunate. Those azaleas are so pretty. Linda
