Azalea 'Sweetheart Supreme'

How to grow Azalea 'Sweetheart Supreme' in NZ

Azalea 'Sweetheart Supreme' grows best in part shade with moist, free draining, slightly acidic soil. Choose a sheltered position protected from harsh afternoon sun and drying winds to encourage healthy growth and prolific flowering. Incorporating compost or organic matter into the soil at planting time improves moisture retention and supports healthy root development. Water regularly during dry periods while the plant establishes. Applying mulch around the base helps conserve moisture, maintain cool root conditions, and suppress weeds throughout the warmer months.
