Rhododendrons are susceptible to various diseases and can be damaged by winter weather. Leaf drying and browning can occur as a result of winter exposure and the small holes you see may be associated with a fungal disease. If this is the case, the leaves may turn reddish brown and remain attached to the plant. To manage this disease, cut out the affected branches a few inches below the affected area and then destroy the branches. You can then spray with a basic copper sulfate fungicide after blooming. Repeat 2 or more times at intervals of 14 days. Best wishes with your rhodie.
