I have 5 weeping cherry trees and only one of them looks like it's dying. What can I do to save this one tree?
There are many things that could be killing the tree. The most common are pests, fungus and watering issues. Treat the plant with a fungicide and a pesticide for possible pest and fungus issues. Also, check the roots to be sure that there is not anything wrong with them that could be preventing it from taking up water.
I planted a weeping cherry tree in my garden about 6 years ago and for the first year it produced shoots that I pruned back off the ground. In subsequent years, it has produced blossoms every spring and also produces leaves, but for the last four seasons it has not produced any more shoots and seems to suffer from leaf curl during the summer. Any idea what may be wrong? Should I be using a fertilizer or some kind of spray?
Sounds like you have leaf spot or leaf curl and you're already on the right track. You should try spraying your tree with a fungicide.
I trim my cherry tree in the spring, it flowers, then gets its leaves as usual, but then the branches grow like crazy, branching out everywhere and all over the ground. What do I do with it?

I have a weeping cherry tree, approximately 1 1/2 meters tall. A new growth branch has been broken off at the point where it meets the trunk. Can it be saved? Appreciate any help.
I planted a weeping cherry tree this spring. It has dropped its leaves and some of the branches on the umbrella are dried and break off. However, there are shoots growing out of the trunk. Should I let them grow or trim them off? If I trim them, will this help the main tree come back next spring? Should I wait until fall to trim them? Also, I planted some Quaken Aspens, and they are growing nicely. Some of them have suckers coming up from the ground around the root base. Should I trim them?

My 12-year-old grafted weeping cherry tree has the bark 'peeling' back at the graft site. It almost looks like the graft is separating and it doesn't look healthy. In addition, it flowered less this spring than it did in previous years. Finally, we always have a bird nest every year at the site and this year we didn't have a nest. I now wonder if the robins thought the tree was 'sick' and didn't nest there because of this problem. Please help me cure my tree.
Your weeping cherry is rejecting the graft. You can try securing it with tree tape but it's most likely a wasted effort. You can learn more about grafting at: https://www.gardeningknowhow.com/ornamental/trees/tgen/can-grafted-trees-revert-to-their-root-stock.htm
