Why are my rhododendron leaves turning yellow?

When rhododendrons turn yellow between leaf veins it is generally a sign of low pH in the soil. Rhododendrons are acid-loving plants. If they are not grown in soil with proper acidity, the plants can exhibit symptoms of iron deficiency, which causes the breakdown of green between leaf veins, and yellowing.
