Lifespan of Azaleas

Azaleas love cool weather.

The azalea is a classic perennial that delights with its beautiful and unique flowers every spring. When planted in a cool location, the lifespan of azaleas can be somewhat prolonged.

Lifespan of Azaleas

Azaleas in Japan have been reported to live for hundreds of years. Shorter lifespans of azaleas occur without proper care.

Geography

Azaleas start to grow buds and leaves, then bloom starting in late winter and early spring before hotter summer temperatures hit. Some varieties also bloom in the fall.

Best Temperatures for Azaleas

Azaleas prefer cooler temperatures, peaking when the outdoor temperature stays between freezing and about 60 degrees.

Considerations

Azaleas do better in bright, filtered light, such as on the north side. Morning sun, with afternoon shade, provides the best combination.

Requirements

Azaleas prefer to be in moist, well-drained soil, with a pH of 4.5 to 6.0. Keep plants well-watered and regularly check pH to extend the azalea lifespan.
