We have several shrubs/bushes around our house (front back left and right) and they all have this same common issue. Any idea what it is and how to correct it?
For these specific bushes, last summer we pulled out several adult shrubs of this flower bed and refilled the holes with new dirt. When giving away the shrubs, a lady who works at a local nursery said "I don't want these ones. They're sick" to shrubs which had this same yellow leaf.
