The azalea thrives when grown in acid soil in mild, humid climates. If grown in filtered sunlight, it profusely blooms in an array of colors. Azaleas cannot tolerate abrupt changes in temperature or high winds. Winds cause leaf scorch and split bark, so it's best to plant the azalea where a building will provide protection from the wind. Some gardeners will plant the azalea on a slope, or provide wind barriers such as evergreen trees planted to the south and west of the plant. If your azalea is already in the ground and you need to protect it from the wind, there are several things you should consider.
Protect the roots from drying winds by applying a 3- or 4-inch layer of mulch around the base of the azalea. Keep it 2 inches away from the bark and spread it to the drip line of the azalea.
Construct a screen over the azalea to block the wind. This can be as simple as a small pile of pine boughs loosely laid over and around the bush or a large piece of burlap draped over it. Whichever material you choose to use as a screen or blanket, it must be porous enough so it doesn't trap heat underneath.
Water or mist the azalea's foliage on windy days. This will provide an increased level of humidity and keep the foliage from drying.
Bring the azalea indoors on windy days, if it is potted.
