Azalea Dorothy Corston
Notify MeAzalea Dorothy Corston is a compact, deciduous azalea prized for its profuse late-spring flowering display. Its vivid orange-red, funnel-shaped flowers are carried in generous clusters, creating a fiery splash of colour that contrasts beautifully with its fresh green foliage. In autumn, the leaves take on warm tones of red and bronze, adding seasonal interest.
Ideal for mixed borders, woodland gardens, or as a vivid feature in acidic soil beds, this variety suits a wide range of garden styles, including cottage and Japanese-inspired plantings. It thrives best in dappled shade or morning sun with protection from harsh afternoon light. Prefers moist, well-drained, humus-rich soil. Space approximately 1-1.2 metres apart for optimal growth and airflow.
Mature size: Forms a rounded shrub reaching around 1.2 metres high and wide.
Trimming: Lightly trim after flowering to maintain a compact shape and encourage bushy growth. Avoid heavy pruning as azaleas form flower buds on old wood.
Deadheading: Gently remove spent flowers by hand to tidy the plant and prevent seed formation, which can sap energy.
Fertilising: Apply an acid-loving plant fertiliser in early spring and again after flowering. Avoid high-phosphorus fertilisers, which can harm root development.
Watering: Keep soil consistently moist, especially during dry spells and the establishment phase. Azaleas dislike drying out but also need good drainage to prevent root rot.
Pest Control: Watch for lace bugs and spider mites, particularly on the underside of leaves. Treat infestations with neem oil or insecticidal soap.
Disease Management: Azaleas can suffer from petal blight and root rot. Remove affected flowers promptly and ensure good airflow. Avoid overhead watering and improve drainage to reduce fungal risks.
