Most deciduous azaleas are hybrids, native to many parts of North America. There are evergreen varieties native to North America, such as plumleaf azalea (Rhododendron prunifolium), but most evergreen azaleas are Asian, native to China, Japan and Korea.
In respect to this, where do azaleas grow best?
A good location is where they receive either dappled sun all day or sun in the morning and light shade in the afternoon. What kind of soil do they like? Azaleas do well in moist, acid (pH 5.5 or so), well-drained soil with lots of organic matter, such as peat, compost, chopped leaves, or ground bark.
Also, how fast do evergreen azaleas grow? Evergreen azaleas, sometimes called Japanese azaleas, are smaller and slower growing, reaching up to 3ft ( up to 90cm) after ten years. Evergreen azaleas are suitable for container growing, due to their size, or smaller gardens.
Just so, how do you care for evergreen azaleas?
Evergreen azaleas do well in partial shade with some wind protection. Deciduous varieties flower more profusely in full sun. Provide well-drained, humus-rich soil that is slightly acidic (pH 4.5–6). Mulch well.
Why are my azaleas not growing?
Too much nitrogen fertilizer can prevent azalea blooming too. Too little sun can also impact flowering, so check to see if the trees around the azalea shrubs are blocking rays and, if so, trim them back. Container azaleas that fail to bloom may be root bound. Check the drainage holes to see if roots are growing out.
