Contorted filbert trees

Question

Will 90 degree heat damage the leaves on a contorted filbert tree and turn them yellow? What can be done about this?
I don’t have a photo.

Answer 1

Heat won't directly cause the leaves to yellow, but during heat like that, the tree could be experiencing water stress, which could cause the leaves to yellow.

I would recommend increasing the water to the plant. This article will also help:
