Azalea is a popular spring-flowering shrub that can put on quite a spectacular flower show. It does, however, need protection from cold winter temperatures. You can help your azalea get ready for the winter by withholding water, beginning in September. This helps the plant harden off before winter. Then, water heavily after the first killing frost. If it is going to be extremely cold and windy, the azalea requires extra protection.
Pound four stakes around the plant, 1 foot away from it and spread equally distant. The stakes should extend higher than the azalea plant.
Place the cloth over the stakes, adjusting it so that it does not touch the foliage and flowers. The fabric should reach the ground.
Staple or nail the fabric to the stakes if high winds are also expected.
Remove the covering if it rains or when the temperatures warm.
