Azaleas

These azaleas are ten years old and they have never produced beautiful flowers. I do give them food but their limbs and foliage look terrible. Right now their leaves are orange with spots of some sorts. I love azaleas, grew up with them at my childhood home. I live in Charleston, SC, don't know if I need to dig them up and throw away. There are six of them. What do you think? They are southern living plants. Thanks in advance for any help.

Cercospora leaf spot, Phytophthora blight, and Rhizoctonia blight are azalea diseases that can cause spots and discoloration on leaves. Azalea rust can also cause an orange appearance as fungi grow on the leaves. See these articles for more information:
