Azaleas – Protection During Winter
Q: After last year’s cold weather our azaleas really took a beating. They have come back but I don’t want to stress them again this year. Would it be a good idea to cover them with burlap?
A: If the shrubs are healthy going into winter, they should withstand normal winter cold just fine. Consider covering them in winter if temperatures drop into the low ‘teens or if it is very windy and cold. Burlap is too heavy for a plant covering, particularly if rain or snow is expected. Instead, lay in a supply of spun-bonded polyester that’s sold as “frost cloth”.
