Azaleas erupt in spring color that stops traffic. Evergreen types dominate southern gardens; deciduous natives thrive in colder zones. The key is acidic soil — test before planting and amend if needed.
Sun: Part shade. Water: Moderate. Zones: 5–9. Height: 2–10 ft. Bloom time: Mid-spring.
Plant in acidic (pH 4.5–6), well-drained soil with morning sun and afternoon shade. Mulch to keep roots cool and moist. Prune immediately after flowering — next year's buds form by mid-summer. Encore series reblooms in fall.
Câu Hỏi Thường Gặp
01 Why are my azalea leaves yellow?
Usually iron deficiency from alkaline soil. Test soil pH — if above 6, amend with soil sulfur or use a fertilizer formulated for acid-loving plants.
02 When should I prune azaleas?
Immediately after flowering — next year's buds form by mid-summer. Any pruning after July removes flower buds. Light shaping is all most azaleas need; heavy pruning should be reserved for rejuvenating overgrown plants.
03 Will Encore azaleas really bloom twice a year?
Yes — Encore series rebloom in summer and fall after the spring show. Need at least 6 hours of sun for reliable repeat bloom (more than traditional azaleas). In shadier spots they'll still flower in spring but not rebloom.
