Q.Jappenese Yew
We have two Jappenese Yews side by side. The one is fine, but the other one has leaves turning yellow. They are on the East side of the house.
What could be causing this to happen?
Thank you,
Karen

I would check soil drainage. Yews need a well drained soil.
Yellowing leaves can indicate watering issues, too much or too little.
It also can be caused by pests and disease.
Inspection of the infected plant for signs of issues would be the 2nd step.
