About Azalea
Rhododendron indicum, commonly known as Japanese or Indian Azalea, is an evergreen or semi-evergreen shrub distinguished by its showy, funnel-shaped blooms, ranging from pure white to intense pinks, reds, and purples. Its leaves are small, oval, and bright green, often turning reddish in autumn or with cold. It is ideal for partial shade gardens, patio pots, or as a low hedge, providing a vibrant splash of color.
Native range
Japan, China, and Taiwan
Care tips
It requires bright but indirect light, avoiding direct midday sun which can scorch its leaves and flowers. Watering should be regular, keeping the substrate consistently moist but never waterlogged, preferably with rainwater or decalcified water, as they are sensitive to chlorine and calcium. It prefers acidic, well-drained, and organic-rich substrates; a common mistake is planting them in alkaline soils, which causes chlorosis and poor growth. It benefits from light fertilization with azalea-specific fertilizer during spring.
