QuestionWhy are my pink and white camellia leaves going yellow and how do I treat them? AnswerCamellias are ericaceous plants, which means they require acid soil, that is a soil with a pH of seven or lower. They can grow in slightly alkaline soils but the tell-tale sign of a camellia growing in the wrong pH is a yellowing of the leaves. There are many different formulations and brands on the market but all are based on chelated iron. Apply several times during the growing season and the leaves should develop the dark green hue, over the next few months.
