Indoor Gardenia Care: Demanding but Rewarding

Gardenias need a simulated subtropical environment: acidic soil, constant moisture, high humidity, cool nights (60–62°F) for buds, and no drafts.

Essential Requirements

• Soil: Acidic (pH 4.5–5.5), porous, moisture-retentive. Use gardenia/azalea mix.
• Water: Keep soil slightly damp always. Use soft, tepid water. Empty saucer after 1 hour.
• Temperature: Days 70–72°F; nights 60–62°F critical for flowering.
• Light: Bright with morning sun.
• Fertilizer: Acid fertilizer monthly; fish emulsion biweekly. Iron chelate if leaves yellow with green veins (chlorosis).
• Pests: Watch for scale, aphids, spider mites, thrips, whiteflies.

Biggest Challenge

Cool nights without drafts. In a Florida condo, this is very difficult. Consider if you can meet these needs before committing.
