Q.What is wrong with our weeping cherry?
We planted this weeping cherry 2 years ago. Last year it was fine. This year, it bloomed beautifully in the spring, but in early July the leaves started wilting and developed black spots (see attached picture). The bark looks fine, but a couple of long branch ends look dead. From this description and picture, do you have an idea if it can be saved?

It appears to have received a little too much water, leading to a fungal infection. You will want to treat the tree itself with a fungicide. This article will help: https://www.gardeningknowhow.com/garden-how-to/info/using-fungicides-in-garden.htm
My personal recommendation is to use DOLMITIC LIME and WETTABLE SULFUR. Just a cup of Dolomite lime and a teaspoon of wettable sulfur scattered around the root area will help, drastically. Do this once per year, and as a spot treatment.
