I'll second what @Ecks from Tex said. Also, make sure you're using a fertilizer designed for camellias. They have ingredients to increase the acid in the soil. You can use spent coffee grounds as well.
Camellia with Yellowing Leaves
2
Based on some reading I have done on this topic, several things can cause a camellias leaves to yellow... does anyone know what this is or what I should do? (See photos) The plants are about 2 years old. Not all leaves are this way but there are more and more each day....
