My weeping cherry tree bloomed then went through a frost and snow. The blossoms are now all brown. Will the tree survive?
A lot depends on the age of the tree and the overall exposure of the cold temperatures.
Newer cultivators are less likely to suffer from the cold exposure.
The blossoms may have been lost but the leaves may be fine.
A sheltered location with protection from the wind will help your tree survive cold snaps.
If you do not see growth on the tree do the scratch test. Scratch the bark of the tree. If you see green they are still alive.
If you do not see green and the branches snap and break, you will want to remove the tree and start again.
Look for cultivators that are hardy to your growing zone.
