Effects

• Azaleas need sun to bloom and grow properly, but they can get too much. Full sun is likely to reduce growth and make the flowers die quicker, while filtered sunlight will create fuller bushes with longer-lasting blooms. Morning sun, with shade during the peak heat of the day, also works well.
  
  

Features

• While azaleas need some sunshine to do well, they should not be planted where they have full sun or direct sun during the heat of the day. The perfect amount of sun for azaleas is that filtered through trees, so that it changes from full sun to shade as the sun moves.
  
  

Misconceptions

• Winter-sun exposure, when the plants are dormant, can be damaging, too. Warmer days can dry out the soil, which can cause root damage. It is a good idea to water the plants deeply during a warm spell in the winter.
  
  

Considerations

• It's more difficult for azaleas to thrive in full sun in the South or in full shade in the North.
  
  

Warning

• Being highly adaptable, azaleas will grow pretty much where they are planted. If the leaves begin to show signs of sunscald, the plant may need to be moved.
