I agree with the article that sweet cherry trees are easier to grow than the cherry trees that produce sour cherries. I couldn't figure out why some of the trees I planted were growing so well and some of the others simply would not take root and grow.
I eventually determined that the trees that were dying were the sweet cherry trees. They could not withstand the hot summer months and they also suffered from the large amounts of rain we sometimes get in late fall. The bottom line was that the sweet cherry trees couldn't stand the drastic changes in weather from one season to the next.
I don't like the sour cherries as well for eating, but I do like the way the trees look when they are in bloom.
