This preserves the rhododendron's natural look. You might need lopping shears or a saw depending on how thick the wood has become at that level.

Facts About Azaleas

Identification

Azaleas have five to vi stamens in their flowers. Evergreen azalea bloom colors range from purple to cerise and deciduous azalea flower colors range from white to pink and yellowish to ruby.

Effects

Rhododendron wilt effects include yellowing leaves, drooping foliage and stunted growth. Petal blight causes tiny rust- or white-colored spots to appear on the petals, while powdery mildew creates a white or gray coating on the leaves.

Prevention

Sun scorch can be prevented by providing belatedly season irrigation before heavy frosts occur. Additionally, planting rhododendrons near buildings or evergreen copse provides shelter from wind, harsh lord's day and cold temperatures. Rhododendrons are more vulnerable to stalk die back when they've experienced water stress. While rhododendrons don't tolerate waterlogged soils, they need evenly moist soil. Assuasive them to dry out makes them more than prone to disease. Curled leaves are the first sign that rhododendrons aren't getting enough water.

• Sun scorch occurs in the winter and is acquired past harsh winter sunlight and cold temperatures, combined with inadequate watering.
