Hi,

I have an azalea on which one section has started to die back (Brown branches / leaves fell off etc). The rest of the leaves have small white spots. Based on a few articles I read this seems like maybe some combination of lacebugs, boring insects, and/or fungus. Not sure.

It is also planted in a location where there used to be a tree stump, which we killed/removed with the help of epsom salt and a drill. The Azalea was planted several weeks after this was done. Could the residual salt have this effect (and only on a limited part of the azalea)?

I've attached photos. What should I do to save this Azalea? It was beautiful when healthy and was expensive!

Thanks

Epsom salt is magnesium sulfate so that shouldn't be the problem. Did anything else happen around the site?

Nothing else happened around the site, although the azalea does get less sun on the back (dying) part of the plant. I have other azaleas in part shade that do fine so didn't think that would be the problem. Wondering if maybe the root ball wasn't opened up enough before planting.

Is it a recent planting?

It was planted a few months ago in the Spring. It was very healthy when purchased from our area nursery (Behnkes), and flowered beautifully for awhile before this issue arose a few weeks back.

I'm not real sure what's going there. Did you check the soil ph? They like acid soil 4.5-6.0 is best.

I haven't checked the soil acidity, but will give that a try. Thanks for your help.
