They were doing fine until the past month when the leaves of both varieties got little brown spots all over them just like those of the maples and other trees around our property which has been attributed to the very high rainfall. A small portion of the azaleas' leaves are yellowing, but all of them look pretty ratty with brown spots and holes all over them. I don't see any sign of insects except for occasional spiderwebs.
My question is, since these are evergreen varieties, will the leaves stay crappy looking, or will the plant eventually grow new leaves in the spring to replace the damaged ones and look okay? I don't want to go spraying poisons on these plants. I am thinking that if they can't survive unaided where I have put them, I will replace them with something tougher like the yews which are flourishing beside them, as are my annuals.
