What to Do When a Potted Azalea Drops Its Leaves? Causes and Solutions

The main causes of azalea leaf drop are improper watering and fertilizing, alkaline soil and water, nutrient deficiency yellowing, and poor root absorption. Azaleas have fibrous roots and are not drought-tolerant, so you must water them promptly during cultivation, but be careful not to overwater; a moderate amount is enough. Normally, you should apply some alum fertilizer water to the azalea appropriately.
