Q.weeping cherry tree
My tree is 3 years old. It bloomed this spring, but then we got some strong northwest winds with cold temps down to 35 degrees. The new leaves, which were very tender, are just wilting up and drying. Will it recover this spring or this year?
Thanks,
Denise

The cold weather and wind certainly harmed or killed off the foliage.
I would give the tree some time to recover.
Do the branches bend or break off when bent?
Do not fertilize until you see active growth.
Give the tree time and hopefully it can recover.
Here are some articles with care and pruning information.
