Azalea Another One

Thanks for sending this long shot; we can now see it’s a Rhododendron. The odd thing is that it’s right next to another Rhododendron which looks healthy. If not for that, we’d suspect winter burn because broadleaf evergreens are very susceptible to wind burn in winter. Winds wick moisture out of the foliage, but because the ground is frozen, the plant can’t absorb more moisture from the soil to replace what it has lost. This often occurs in Jan-Feb. The damage will not heal, so your best bet is to prune off the damaged foliage and stems and wait for new growth. In the future, you could spray with an antidessicant like Wiltpruf in winter. This slows the evaporation of water from the foliage and can help prevent winter wind burn. However, since you have one healthy Rhodie next to one ailing Rhodie, we suggest you show this photo to a local garden center or coop extension agent. You may need to have someone come examine the soil or your shrub’s root system. Good luck!
