After the blooms fade, Christmas Bells can be planted in the ground in a full sun area (in the appropriate climate zone.) In warmer climates, plant in lightly shaded areas. After blossoms have faded, cut the plant back without cutting into leafless wood. Periodic feeding with iron sulfate will keep the pH acidic but discontinue this before buds appear. Ericas cannot tolerate freezing temperatures; therefore, they would not survive outdoors in cold areas.
