Hi. I live in the sandhills of North Carolina. I have 8 Carissa Holly which were planted about 5 years ago. Last year I noticed one of them was looking sparse. This year the two next to it are very sparse. There was no new growth on any of the three. But, on the other side of my porch stoop there are 5 holly which had vigorous new growth and look good. It's as if a disease invaded one then transferred to the other two. Both sides are drip irrigated. I am attaching a picture. I would appreciate any help I gan get. Thanks! Emerson
