I have about 4 cherry blossoms in my yard. 2 with burgundy flowers and 2 with pink flowers. My burgundy ones are dying but still having new growth. I do not know how to save the trees or heal them, so I took a couple of new growths in all respect to the tree and said to it that I will grow it again. I will make a new line of cherry blossom trees in it's honor.
The pink trees we have seem to be healthy. They are a different kind I suppose as they do not blossom the same as in your pictures. Yours are full and fluffy. Mine are smaller and not so thick.

I find it so interesting that there are many varieties of the same plant. It is fascinating.
I love your pictures and the last one is a picture of a thousand words. Beautiful, stunning, soft, tranquil, innocent... It matches with you perfectly and just makes it all so radiant. Bathe in flowers!
