Question
Our camellia plant has small, oval and circular shaped rust-colored spots mostly on the underside of the leaves.  However, some spots are now beginning to show on the top side of the leaves as well.  This does not match the description I read for root rot or petal blight.  The blooms on our plants are beautiful (at least, the ones that are blooming).  They are newly transplanted from a nursery.  So ph may be an issue.  Do you have any ideas or thoughts on this, or what this could be? If so, do you have a pesticide free solution?

Answer
Camellias are prone to suffer from oedema, a condition where there is too much water in the leaves and the pressure actually causes blisters on the leaves that appear corky and rough.  This condition does not harm anything and there is no way yo make it go away.  You will have to wait for the new growth to replace those old leaves.
