Gardenia Bonsai Pair: Yellow Leaves, Overwatering Suspected

Two Gardenia bonsai in Phoenix, AZ; west window; daily distilled water + biweekly gardenia food; misting; one yellowing, then both.

Likely Overwatering

• Daily watering + humidity tray + misting = waterlogged roots.
• Gardenia needs moist but well-drained; let top 1 in. dry.
• West window in Phoenix = intense heat; may need more water but not constant saturation.

Fixes

1. Check soil daily; water only when top 1 in. dry.
2. Move outdoors (part shade) for better light/air.
3. Stop fertilizer until healthy.
4. Use organic fertilizer later (gentler).
