The same thing happened to my friends Dogwood tree. I wouldn't be surprised if it had something to do with last seasons winter.

Quite spectacular every year for almost 40, with this Spring only a few blooms. The natives on the property behaved the same. Few flowers. I only assume that weather interfered, somehow, in the making up of buds, last Summer. Not something I expect will occur again, but we will see.

I have several varieties of dogwoods, some bloomed well, some sparsely and my pink stellar one not at all. I thought it had to do with all the cloudy, rainy days we had last year. Maybe not enough sunlight to set buds properly?

I had the same experience this year. My dogwood which is usually the showpiece of the neighborhood was very disappointing this year. I got about half the flowers I normally do. Not sure what the cause is but it definitely worried me. I'm hoping it was the cold...and long winter.

My dogwoods flowered normally, but I water regularly. Last summer was very hot & dry, possibly interfering with bud set.
