Choosing the Right Soil

When it comes to successfully propagating Rex Begonia in soil, selecting the right type of soil is crucial. This will provide the necessary nutrients and drainage for the plant to thrive.

Selecting a well-draining soil mix

Rex Begonias prefer soil that is well-draining to prevent waterlogged conditions, which can lead to root rot. A good soil mix for Rex Begonias is one that contains a combination of peat moss, perlite, and coarse sand. This will allow excess water to drain away quickly while still retaining enough moisture for the plant.

Ensuring proper pH levels

Rex Begonias thrive in slightly acidic soil with a pH level between 5.5 and 6.5. It is important to test the pH of the soil before planting or propagating Rex Begonias to ensure that it falls within this range. If the soil is too alkaline, you can lower the pH by adding sulfur or peat moss.

Adding organic matter for nutrients

Organic matter such as compost or well-rotted manure can be added to the soil mix to provide essential nutrients for Rex Begonias. This will help the plants grow healthy and strong, promoting successful propagation. Be sure to mix the organic matter thoroughly into the soil before planting or propagating Rex Begonias.

By choosing the right soil mix, ensuring proper pH levels, and adding organic matter for nutrients, you can set your Rex Begonias up for success in propagation.

Preparing the Begonia Cuttings

Selecting healthy stems for propagation

When selecting stems for propagation, it is important to choose healthy ones that are free from pests or diseases. Look for stems that are firm and have a vibrant color, as these are indicators of a strong plant that will propagate successfully.

Trimming the cuttings at a node

Once you have selected your stems, it is crucial to trim them at a node. A node is where a leaf or stem attaches to the main stem, and this is where new roots will form. Use clean, sharp scissors to make a clean cut just below a node to ensure successful propagation.

Allowing the cuttings to callus

After trimming the cuttings, it is essential to allow them to callus before planting them in soil. This process involves letting the cut ends dry out and form a protective layer, which will help prevent rotting and promote healthy root growth. Place the cuttings in a warm, dry location for a few days to allow this callusing process to occur before planting them in soil.

Planting and Caring for Begonia Cuttings

When propagating Rex Begonia in soil, it is important to follow a few key steps to ensure the success of your cuttings. One of the most crucial aspects of this process is planting and caring for the cuttings properly.

Creating a suitable planting hole

Before planting your Begonia cuttings, make sure to create a suitable planting hole in the soil. The hole should be deep enough to accommodate the roots of the cutting and wide enough to allow for proper growth. You can use a small trowel or your fingers to gently dig the hole, being careful not to damage the roots.

Placing the cuttings in the soil

Once you have created the planting hole, carefully place the Begonia cuttings into the soil. Make sure that the roots are fully covered and that the stem is securely planted. Gently pat down the soil around the cutting to ensure that it is stable and in place.

Providing the right amount of moisture and light

After planting the cuttings, it is important to provide them with the right amount of moisture and light. Begonias thrive in well-draining soil that is kept consistently moist but not waterlogged. Water the cuttings regularly, making sure to keep the soil damp but not soggy.

In terms of light, Begonias prefer bright, indirect light. Place the cuttings in a location where they will receive plenty of natural light, but avoid direct sunlight as this can scorch the delicate leaves. With the right care and attention to detail, your Begonia cuttings should thrive and grow into beautiful, healthy plants.


In conclusion, successfully propagating Rex Begonia in soil requires patience, attention to detail, and the right techniques. By following the top tips outlined in this article, such as choosing the right soil mix, providing adequate moisture and humidity levels, and using the correct propagation methods, you can increase your chances of successfully growing new plants from cuttings. Remember to keep a close eye on your plants, monitor their growth progress, and make adjustments as needed. With dedication and care, you can enjoy a beautiful collection of Rex Begonias in your home or garden.
