Of course, it is good to make analysis of the soil in which grows your azaleas, and make sure that the substrate is not really suitable for plants belonging to the family Ericaceae and the genus rhododendron.
If it is impossible to check the soil for chemical composition, and if factors such as incorrect irrigation and the presence of pests is possible, try to acidify the soil. To do this, once a month watering the azaleas with water, which added to the vinegar or citric acid (juice).
