Yellowing leaves are generally an indicator of watering issues. To little or to much.
If the area is dry, I would add some additional water. 2 to 3 inches of hardwood mulch can help with moisture retention.
Also check for insects or fungus issues. Neem Oil is a good treatment for either as it works as both an insecticide and fungicide.
