Azalea Problem

Does this look like a nitrogen deficiency? I'm planning on top dressing with sheep manure in the next couple of days and I hope it corrects the problem.
Thank you!

RE: Azalea Problem

Nitrogen deficiency would be (dark) green new leaves with pale or yellowing older leaves.

So, no, not nitrogen deficiency.

The pale leaf edges suggest a root problem. Perhaps due to unfavorable pH, perhaps to something else.

RE: Azalea Problem

It is planted on either side of emerald cedars. There is also hostas, potential, hydrangea, and cotoneaster around the azalea and nothing else is having problems. Perhaps tomorrow I can do some exploratory digging to see if anything is bothering the roots.

RE: Azalea Problem

Azaleas do better with more acid soil than all the others you named.

What's your prevailing sol pH?

RE: Azalea Problem

Yes, symptoms look more like iron chlorosis than anything else and that is a direct effect from soil that is insufficiently acidic.

RE: Azalea Problem

I have added iron chelate to the soil and top dressed with sheep manure.
