Azalea

How to care for azalea

• Light: Prefers partial shade, especially protection from intense afternoon sun. Some varieties can tolerate more sun in cooler climates.
• Water: Keep the soil consistently moist but well-drained, especially during blooming and dry periods. Avoid letting the soil dry out completely.
• Soil: Requires acidic, well-draining soil rich in organic matter. A pH between 4.5 and 6.0 is ideal.
• Temperature: Hardy in many zones, but generally prefers cooler temperatures, around 60-75°F (15-24°C). Protect from extreme heat or frost.
• Humidity: Benefits from moderate to high humidity, especially during hot, dry spells. Mulching can help retain soil moisture.
• Fertilizer: Fertilize in spring after flowering with an acid-loving plant fertilizer. Avoid over-fertilizing.
• Propagation: Propagate primarily through stem cuttings taken in early summer. Softwood cuttings root best with rooting hormone.

Is azalea toxic to pets?

Not pet-safe. Highly toxic to cats, dogs, and humans; ingestion can cause vomiting, diarrhea, cardiac issues, and death. See our guide to toxic plants for cats and dogs.

Common problems

• Yellow leaves with green veins (chlorosis): Indicates iron deficiency, often due to high soil pH; use an acidic fertilizer or iron supplement.
• Lace bugs: Cause stippling on leaves; treat with insecticidal soap or horticultural oil, focusing on the undersides of leaves.
