Propagating Rex Begonias

Rex Begonias are a popular choice for indoor plants due to their beautiful foliage and low maintenance requirements. If you’re looking to expand your collection of Rex Begonias or share them with friends and family, propagation is a great way to do so.

Propagating through leaf cuttings

One of the easiest ways to propagate Rex Begonias is through leaf cuttings. Simply select a healthy leaf from the parent plant and cut it into smaller sections, making sure each section has a vein running through it. Place the leaf cuttings in a pot filled with a well-draining potting mix and keep them in a warm, humid environment. Roots should start to develop within a few weeks, and new plants will eventually sprout from the leaf cuttings.

Propagating through division

Another method of propagating Rex Begonias is through division. This involves separating a mature plant into smaller sections, each with its own roots and stems. Carefully remove the plant from its pot and gently separate the root ball into smaller sections. Plant each section in its own pot with fresh potting mix and water thoroughly. With proper care, the divided plants will establish themselves and continue to grow.

Tips for successful propagation

  • Choose healthy parent plants with strong growth.
  • Use a well-draining potting mix to prevent root rot.
  • Keep the propagating plants in a warm, humid environment to encourage root growth.
  • Water the new plants regularly, but avoid overwatering to prevent root rot.
  • Monitor the plants for any signs of pests or diseases and take action promptly.

By following these tips and methods for propagating Rex Begonias, you can easily expand your collection and share the beauty of these plants with others. Happy gardening!

Caring for Propagated Rex Begonias

After successfully propagating your Rex Begonias, it is important to continue caring for them properly to ensure their health and vitality. Here are some essential tips for caring for your propagated Rex Begonias:

Light and humidity requirements

Rex Begonias thrive in bright, indirect light. They should be placed near a window where they can receive plenty of sunlight, but be sure to avoid direct sunlight as this can scorch their delicate leaves. Additionally, Rex Begonias require high humidity levels to thrive. You can increase humidity by misting the leaves regularly or placing a humidifier near the plant.

Watering and fertilizing tips

When it comes to watering your propagated Rex Begonias, it is important to keep the soil consistently moist but not waterlogged. Water the plant when the top inch of soil feels dry to the touch. Additionally, fertilize your Rex Begonias every 2-4 weeks during the growing season with a balanced, water-soluble fertilizer to promote healthy growth.

Common pests and diseases to watch out for

While Rex Begonias are relatively low-maintenance plants, they are susceptible to a few common pests and diseases. Keep an eye out for pests such as aphids, spider mites, and mealybugs, which can be treated with insecticidal soap or neem oil. Additionally, watch for signs of powdery mildew or leaf spot diseases, which can be prevented by ensuring good air circulation around the plant and avoiding overhead watering.

By following these care tips, you can ensure that your propagated Rex Begonias remain healthy and vibrant for years to come.


In conclusion, propagating Rex Begonias can be a rewarding experience for any gardener.
