Good question. I used tro think sulfur would adjust the pH.

Beware of so-called tree experts who do not understand tree biology.
Storms, fires, floods, earthquakes, and volcanic eruptions keep reminding us
that we are not the boss.

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?
TIA
