Best Time to Plant Azaleas in Tennessee

In southeastern Tennessee (Zones 6–7), spring and fall are ideal for planting azaleas due to mild temperatures. However, with attentive watering, they can be planted in summer or winter too.

Key care: Water new plants with 5 gallons per week if no rain falls. Apply an acid-loving fertilizer like Espoma Holly-tone in spring and fall. Monitor for lace bug damage—treat promptly if seen. Azaleas are broadleaf evergreens; they prefer acidic, well-drained soil rich in organic matter. Mulch with pine bark or needles to conserve moisture and maintain acidity.

Choose a site with morning sun and afternoon shade for best performance. Local garden centers can recommend varieties suited to your specific conditions.
