when do azaleas bloom

Azaleas typically bloom in the spring, with the exact timing depending on the variety and local climate conditions. Generally, early bloomers start flowering from late winter to early spring (around February to April), mid- season bloomers flower in late spring to early summer (May to June), and late or fall-flowering varieties bloom from midsummer into fall (mid-July to October). Some hybrid azaleas can even rebloom multiple times from spring through fall. In temperate Northern Hemisphere regions, azaleas usually bloom in April and May, with flowers lasting several weeks. Weather plays a significant role in bloom timing: warmer, early springs lead to earlier blooms, while cooler springs delay them. In USDA zones 9 and warmer, some azaleas can bloom again in the fall. Overall, azaleas form flower buds in early summer if they receive adequate moisture, require a period of cooler temperatures below 50°F in winter to bloom all at once in spring, and typically stay in bloom for about two weeks, though this can vary by species and environmental conditions.
