I have an azalea in a large pot on the E. side of the house
(So. Calif coastal), that has turned chlorotic. I gave it
iron twice, but has had no effect; leaves still have that
tell-tale appearance.

Light, water and fertilizer are normal.

Any suggestions?

FWIW, here's the reply I received from my local nursery:

Ironite is the right way to go, but if the roots do not get enough
oxygen to enable the plant to take in the trace elements (Iron,Zinc,
Manganese etc) it will not help. What I mean with enough Oxygen, is
that Azaleas could easily be planted too deep - they like to have the
root ball be exposed, so I would recommend scraping the top layer away
from the trunk and not keeping the soil soaked. A liquid fertilizer
sprayed on the leaves such as soil acidifier should rectify the
problem faster than if the nutrients were to be absorbed by the roots
and transferred to the leaves.
