Ask-a-Dave's-Gardener: Dying Azalea Help, 1 by ABSinger

So our new azalea(planted late last Summer) didn’t bloom much and then started dying back. Leaves on one side curled up and fell off. Thought it might be a soil or root issue. Dug it up and remediated the soil with peat, poop and topsoil as it is in a clay rich spot. Seemed to be doing ok.

We went Away for a few days and it took a turn for the worse. I think it may be lace bugs or some other pest. Any suggestions?
