Watering & Care

Caring for a Rex Begonia requires attention to its specific needs, but following these guidelines will ensure it thrives:

  1. Light: Rex Begonias prefer bright, indirect light. Too much direct sunlight can scorch the leaves, while too little light can result in poor growth and dull leaf colors. A north or east-facing window is ideal.
  2. Watering: Keep the soil consistently moist but not waterlogged. Water the plant when the top inch of soil feels dry, and avoid letting the soil dry out completely. Be careful not to overwater, as this can lead to root rot.
  3. Soil: Use a well-draining, lightweight potting mix. A mix containing peat moss, perlite, and regular potting soil works well.
  4. Temperature & Humidity: Rex Begonias thrive in temperatures between 60-75°F (16-24°C) and prefer high humidity. They can be sensitive to temperature fluctuations and drafts. Increase humidity by misting the plant regularly or using a humidifier.
  5. Fertilizing: Feed the plant with a balanced, water-soluble fertilizer every 2-4 weeks during the growing season (spring and summer). Reduce fertilizing in the fall and winter months.
  6. Pruning: Remove dead or yellowing leaves and spent flowers regularly to encourage new growth and maintain the plant’s appearance. Pruning can also help control the size and shape of the plant.
  7. Repotting: Repot your Rex Begonia every 1-2 years to refresh the soil and provide room for growth. Use a pot that is only slightly larger than the current one to prevent excessive moisture retention.
