Indoor Azalea Tree: Pot Selection, Watering, and Year-Round Care

Don't Repot in Bloom

Dee's new azalea tree should stay in its current pot until flowers fade. Repotting now drops buds.

Ideal Pot and Soil

• Shallow "azalea pot" (wider than deep) or standard clay pot inside decorative cachepot.
• Clay allows root aeration; essential for azaleas.
• Repot after bloom into peat-enriched acidic mix, pot only 2 inches larger.

Watering Regime

• Use acidic water: 1 tsp vinegar per gallon.
• Bottom water: sit in water until soil surface damp.
• Keep petals dry; never let sit in drainage water.
• Water when top inch feels dry.

Seasonal Cycle

1. Bloom: Cool (55–60°F), bright indirect light.
2. Post-bloom: Repot, move outdoors to sun.
3. Summer: Full sun, regular water, biweekly fertilizer.
4. Fall: Bring in before frost.
5. Winter dormancy: 35–50°F, bright light (fluorescent ok), minimal water.

Outdoor Option (Portland, Zone 8b)

Plant in ground with winter mulch and frost blankets on freezing nights. Or keep in whiskey barrel on balcony for easier protection.
