🌱 How to Care for Gardenia to Prevent Mealybugs?

💧 How to Water

Water when the top inch of soil feels dry. Keep soil consistently moist but never waterlogged. Use room-temperature rainwater or filtered water, as gardenias are sensitive to hard water. Reduce watering in winter but never let the soil dry out completely.

☀️ Lighting

Provide bright indirect light or morning sun with afternoon shade. Gardenias need 4-6 hours of filtered sunlight daily. Too much direct sun scorches leaves and causes bud drop; too little light reduces blooming significantly.

🪴 Ideal Soil

Use acidic, well-draining soil rich in organic matter. A mix of peat moss, pine bark, and perlite works well. Maintain pH between 5.0 and 6.0. Avoid planting near concrete foundations, which can raise soil pH and cause chlorosis.
