Balancing Water, Humidity, and Pests for Indoor Gardenias

Balancing Water, Humidity, and Pests for Indoor Gardenias

Gardenias need high humidity but hate wet feet. Your current setup—rocks in the pot bottom, pot on a rock tray—lets the soil reabsorb drainage water, keeping roots too wet. This causes yellow leaves when you water, and bud drop.

Fix the Drainage

• Elevate the pot on stones above the drainage water, or use a larger humidity tray under the drainage tray (which you empty completely after watering).

Control Spider Mites

Spray the plant with rubbing alcohol in a spray bottle. Keep night temperatures in the low 50s°F and days around 65°F. Place buckets of water in the room to raise ambient humidity.

Watering

Water thoroughly, then empty the drainage tray immediately. Don't let the plant sit in water. The "every 10–14 days" schedule is fine if drainage is correct.

Cool nights, good drainage, and alcohol sprays will stop the bud drop and mites.
