Growing Azaleas Indoors: Tips for Beautiful Houseplant Blooms

Florist azaleas (Rhododendron simsii hybrids) bring spring color indoors with proper care. They need cool temps, bright indirect light, acidic soil, and consistent moisture.

Essentials

• Pot: Clay with drainage.
• Soil: Peat-based, acidic potting mix.
• Light: Bright, indirect (east window); 55–60°F prolongs bloom.
• Water: Keep soil damp, not soggy. Mist daily if buds unopened. Use vinegar-water (1 Tbsp/gal) if tap water is alkaline.
• Deadheading: Remove spent flowers/leaves daily.
• Fertilizer: Acidic houseplant feed monthly after flowering.
• Repotting: Every 2–3 years in late summer/early fall; larger clay pot, fresh peat mix.

Cool, moist, acidic conditions mimic their mountain origins and keep them blooming for weeks.
