Begonia conchifolia, commonly known as the shell-leaf begonia, is a beautiful plant that is relatively easy to care for. Here are some simple care tips:

1. Light: Begonia conchifolia prefers bright, indirect light. Avoid direct sunlight as it can scorch the leaves.

2. Watering: Keep the soil consistently moist but not waterlogged. Water when the top inch of soil feels dry to the touch. Begonias are sensitive to overwatering, so ensure good drainage.

3. Humidity: Begonias thrive in high humidity. You can increase humidity by misting the leaves or placing the pot on a humidity tray.

4. Temperature: Keep the plant in a warm environment, ideally between 65-75°F (18-24°C). Avoid cold drafts and sudden temperature drops.

5. Soil: Use a well-draining potting mix that retains some moisture, such as a mix designed for African violets or begonias.

6. Fertilizing: Feed your begonia with a balanced, water-soluble fertilizer diluted to half-strength every 4-6 weeks during the growing season (spring and summer).

7. Pruning: Regularly pinch back the growing tips to encourage bushier growth and remove any leggy or yellowing leaves.

8. Propagation: Begonias can be propagated from stem cuttings. Simply cut a healthy stem with a node, dip it in rooting hormone (optional), and plant it in moist potting mix.

By following these care tips, you can enjoy a healthy and thriving Begonia conchifolia in your home or garden!
