When hydrangea leaves turning yellow turn yellow it is a sign that the plant needs to put its energy into the most important task, producing blooms. This means that it can’t give enough attention to its lower leaves, which also need sunlight to photosynthesize, so it lets them go and puts all of its effort into flowering.

One of the main reasons for hydrangea leaves turning yellow is nutrient deficiency. Hydrangeas are heavy feeders and they need a steady supply of nutrients in order to thrive. This can be caused by a lack of water, soil deficiencies, improper fertilization or even pests and disease.
