Azalea Care: Growing Healthy, Flowering Rhododendrons

Azaleas (subgenera Tsutsuji, Pentanthera of Rhododendron) are spring-blooming shrubs for shade. They need acidic soil (pH ≤5.5), moisture, and moderate temps (68°F ideal).

Key Requirements

• Light: Dappled shade; near pines/oaks ideal.
• Soil: Acidic, organic-rich. Test pH; amend with peat/sulfur if needed.
• Water: Deep, regular soakings—not sprinklers. Keep soil moist.
• Fertilizer: Cottonseed meal (organic, acidifying).
• Mulch: 1″ shredded pine needles in late fall. No hardwood bark (raises pH). Keep off stem.
• Disease Prevention: Clean debris; organic fungicides for fungal issues.

Once established in the right spot, azaleas are long-lived, low-maintenance spring showstoppers.
