Gardenia Indoor Care: Light, Humidity, and Aphid Control

Critical Light Correction

Your gardenia needs a south, east, or west window with coverings OPEN all day. North window + vent proximity = insufficient light. Weak plants attract pests (aphids).

Immediate Action Plan

1. Move to sunny window (vent proximity acceptable)
2. Run humidifier next to plant
3. Treat aphids: Take outside, apply garden center insecticide, return
4. NO repotting—recent upsize + Miracle-Gro = root rot risk

Gardenia Requirements

• High light (direct sun OK indoors)
• High humidity (humidifier essential indoors)
• Acidic soil (avoid Miracle-Gro standard mix)
• Consistent moisture (not wet, not dry)
• Cool nights preferred for bud set

Why Buds Drop

Low light + low humidity + pest stress = bud blast. The plant aborts reproduction to survive. Correct the environment, and new buds will hold.
