Leaf scorch on rhododendrons is a response to stress. Water stress can occur under both extremes of flooded, overly-saturated soils or under drought conditions when too little water is present. Root or stem damage due to disease or transplant shock can also cause scorch symptoms. High soil pH and exposure to drying winds are other possible causes of leaf scorch. Too much salt in soil or irrigation water, or using large amounts of inorganic fertilizers, or a combination of all three can cause symptoms as well.
Symptoms include browning of tips or margins of leaves, with the damage sometimes spreading to the center of the leaf. The south/southwest side of the plant is the most likely to be damaged by direct sunlight, but plantings also might be damaged by reflected sunlight.
Correct alkaline soil pH by adding organic matter or sulfur to make it more acidic. An easy way to do this is to switch from the Osmocote to a fertilizer specifically formulated for Azaleas/Rhodies.
Provide adequate soil moisture by irrigation where dry soil is a problem. If boggy conditions are at fault, it may be necessary to relocate the plant or to use raised beds.
Shelter susceptible plants from drying winds, either with other plantings or by planting near structures.
