rosemary leaves are turning black - hot weather - too much water
I have a rosemary in a pot in my home. It was doing great for a week or two, but now it is dying. I have read here, that it shouldn't be watered to much, but the leaves have started to turn black and dry out, so I have been giving it more water. This does not seem to be helping. It has been very hot and humid here (95 degrees) could it be the weather or does it look like it might have a disease.
I do not see any bugs or strange growths on it, I have no idea what I am doing wrong.
Here is a picture, is this plant a lost cause?
Thanks for any help!
