Our north facing, 13-year-old Holly is dropping its leaves. No insect problem that I can see. Nothing different has been done to the bush. We live in southwest Ohio. The stems of the affected area is just drying up and dying. Any suggestions?

This could be a watering or nutrient issue. Give it more water and have the soil tested to find out if it is deficient in anything, then fix as needed.
