Overwatering: Begonia Rex plants are susceptible to root rot, so avoid overwatering. Ensure the soil is well-draining and allow it to dry out slightly between waterings.
Direct Sunlight: Begonia Rex plants prefer bright, indirect light. Direct sunlight can scorch their delicate leaves, leading to damage or discoloration.
Low Humidity: Begonia Rex plants thrive in high humidity environments. Mist the leaves regularly or place a humidifier nearby to maintain optimal humidity levels.
Cold Drafts: Begonia Rex plants are sensitive to cold drafts. Keep them away from drafty windows or doors, especially during the winter months.
Poor Drainage: Ensure the pot has proper drainage holes to prevent water from pooling at the bottom, which can lead to root rot.
Overcrowding: Avoid overcrowding Begonia Rex plants with other plants in the same pot. Give them ample space to grow and spread out.
Overfertilizing: Begonia Rex plants are sensitive to fertilizer. Use a diluted, balanced fertilizer sparingly during the growing season, and avoid fertilizing during the winter months.
Ignoring Pests: Keep an eye out for pests like spider mites, mealybugs, and aphids, which can infest Begonia Rex plants.
