Problem With My Climbing Hydrangea

Question

I planted two climbing hydrangea last September and they were both doing well until two weeks ago when one started turning yellow. Please What is the problem and what can I do to correct it? Thank yoy

Answer 1

According to the second article below, their leaves turn yellow in the fall, before dropping. If you think it is something else, check for cultural problems like compacted soil, chlorosis of leaves, and inspect underside of leaves for insects.
