Q.Snow fountain weeping cherry tree.
Bought a snow fountain weeping cherry tree last year,we planted it as the instructions said,we had a really long and cold winter, still had snow in the middle of April,it only had a very few blooms on it that the wind blew away,anyway it still has little buds that are black on it like it’s going to either blooms flowers or leaves,I have checked it the limbs are pliable and it has new shoots at the base I need to remove,but it looks healthy,what can I do to help my tree?

The shoots at the bottom are coming from the roots that the top is grafted onto.
If the tree limbs are still alive; bend do not snap off, you can give the top more time to recover. Remove the growth at the root line.
Make sure the tree is receiving enough water.
Most reputable growers will guarantee a new planting for 1 year, so if you do lose the tree you should be able to get a replacement.
