If the leaves first turned yellow, then this may be a symptom of
iron deficiency, which is sometimes encountered in acid soils, where
the iron stays locked in the soil. This can be remedied by
feeding the plant sequestered iron, which is reckoned to be
a good all round "tonic" for camellias, azalias etc. As it
would need to be, judging by the price they charge for individual
sachets. However a single feeding appears to eliminate yellowing
leaves on quite large bushes 5ft plus, for many seasons to come.

That goes against what I understood, which is that acid loving plants
have difficulty in taking up iron in *alkaline* soils, as evidenced by
yellowing of leaves, when sequestered iron may help.

Someone please un-confuse me!
