1: 1. Overwatering: Avoid soggy soil by letting it dry out between waterings. 2. Poor Drainage: Use well-draining soil to prevent root rot. 3. Improper Pruning: Trim after blooming to avoid cutting off buds.

2: 4. Lack of Sunlight: Place in a sunny spot for optimal growth. 5. Not Enough Fertilizer: Feed with a balanced fertilizer in spring and summer. 6. Ignoring Pests: Watch for aphids and whiteflies and treat promptly.

3: 7. Wrong Temperature: Keep gardenias warm in winter to prevent stress. 8. Using Wrong Soil pH: Aim for slightly acidic soil for healthy plants. 9. Planting Too Deep: Keep roots at soil level when planting to avoid suffocation.

4: 10. Neglecting Pruning: Trim dead branches to encourage new growth. 11. Not Mulching: Mulch to retain moisture and protect roots. 12. Overcrowding: Space plants properly to prevent competition for nutrients.

5: 13. Underwatering: Keep soil consistently moist, but not waterlogged. 14. Insufficient Drainage: Ensure pots have drainage holes to prevent root rot. 15. Overfertilizing: Follow package instructions and avoid excess nitrogen.

6: 16. Inadequate Sunlight: Provide at least 6 hours of sunlight per day. 17. Skipping Pest Prevention: Use organic sprays to deter aphids and scale. 18. Cold Exposure: Protect plants from frost and cold drafts indoors.

7: 19. Incorrect Soil pH: Test soil and adjust to pH 5 to 6. 20. Deep Planting: Plant gardenias slightly above soil level for optimal growth. 21. Infrequent Watering: Maintain consistent moisture levels for healthy roots.

8: 22. No Fertilizer: Feed gardenias with slow-release fertilizer in spring. 23. Pruning at Wrong Time: Trim after blooming to avoid cutting off buds. 24. Overcrowding: Provide adequate spacing between plants to prevent competition.

9: 25. Ignoring Signs of Stress: Monitor for yellow leaves and wilting. 26. Lack of Air Circulation: Ensure good airflow to prevent mold and pests. 27. Not Planning Ahead: Research care requirements before planting gardenias.
