mexican heather trouble
Hi, I live in South Florida, and planted, a little over a year ago, several borders of Mexican Heather, purple. They were doing very well until recently when the leaves began to turn yellow. Now several of the plants have been reduced to "sticks" and the rest look just awful. I have had a fungus problem on my grass so I thought that it might be related.
How can I tell for sure what the problem is, and if it is a fungus, does anyone know the best way to treat.
