From selecting the right stems to creating the perfect humid environment for new roots, we cover everything you need to know to be successful. Growing your own plants is a rewarding journey that turns a single purchase into a lifetime of beautiful blooms.

Why Grow Begonias From Cuttings?

Growing begonias from cuttings is not just about saving money; it is about preserving the plants you love. Begonias are incredibly diverse, and many of the most stunning varieties are hybrids. Because these hybrids do not always grow "true" from seed—meaning the offspring might look different than the parent—taking a cutting is the only way to ensure you get an exact clone of the original plant.

Cuttings also give you a significant head start compared to starting from tiny, dust-like seeds. A stem cutting already has a developed structure and the energy needed to produce leaves and flowers quickly. In many cases, a cutting taken in late summer can become a healthy, blooming plant by the following spring. It is a practical way to multiply your collection and ensure that if one plant struggles, you have several backups ready to take its place.

Understanding the Different Types of Begonias

Before you reach for your shears, it helps to identify which type of begonia you are growing. While almost all begonias can be grown from cuttings, the method that works best often depends on the plant’s growth habit.

Fibrous-Rooted Begonias (Wax Begonias)

These are the classic bedding plants often seen in garden borders and hanging baskets. They have succulent, waxy leaves and bushy growth. These are most commonly propagated via stem cuttings. They root very quickly in either soil or water, making them a great choice for beginners.

Cane-Like Begonias (Angel Wing)

Named for their long, upright stems that look like bamboo and their decorative, wing-shaped leaves, these begonias are favorites for indoor growing. They respond very well to stem cuttings. In fact, pruning these plants for cuttings often helps the parent plant become fuller and less "leggy."

Rhizomatous and Rex Begonias

Rhizomatous begonias grow from a thick, creeping stem called a rhizome that sits on or just below the soil surface. Rex begonias, a sub-group known for their spectacular leaf colors and patterns, fall into this category. These plants are unique because they can be propagated from a single leaf or even just a piece of a leaf.

Tuberous Begonias

Tuberous begonias grow from a potato-like underground structure. While they are usually grown from these tubers, they can also be grown from stem cuttings. This is often done early in the season to increase the number of plants you have for summer displays.

The Best Time to Take Cuttings

Timing is an important factor in gardening success. For begonias, the best time to take cuttings is when the plant is actively growing. For most gardeners, this is during the spring and summer months. During this period, the plant’s cells are dividing rapidly, and the "parent" plant has plenty of energy to heal from the cut while the "baby" plant has the vigor to produce new roots.

If you are growing begonias outdoors and live in a region with cold winters, late summer is an ideal time to take cuttings. By taking snippets in August or September, you can root them indoors and keep them as houseplants over the winter. This allows you to bring your favorite varieties back outside once the weather warms up in the spring.

Preparing Your Propagation Space

Success starts with a clean environment. Because a cutting is essentially an open wound, it is susceptible to rot if the conditions are not right. You do not need a professional greenhouse, but a few basic supplies will make a big difference.

Choosing the Right Medium

The "medium" is simply what you use to hold the cutting while it grows roots. While you can use standard potting soil, we often recommend a lighter, sterile mix. Good options include:

• Perlite: This volcanic glass looks like small white stones and provides excellent drainage, which means water leaves the soil quickly while still keeping things moist.
• Vermiculite: A mineral that holds more water than perlite but still allows for plenty of air.
• Seed Starting Mix: Usually a blend of peat moss or coco coir and perlite.

The goal is to provide a balance of moisture and air. If the medium is too heavy or stays too wet, the stem will rot before it can grow roots.

Containers and Tools

Cleanliness is vital. Always use sharp scissors or a razor blade to make your cuts. Dull blades can crush the plant's cells, making it harder for the cutting to take up water. Before you start, wipe your tools with rubbing alcohol to prevent the spread of any bacteria or fungus. For containers, anything with drainage holes will work. Small plastic pots, yogurt containers with holes poked in the bottom, or even clear plastic take-out boxes make excellent "mini-nurseries."

Key Takeaway: Using a sterile, well-draining medium and clean tools is the easiest way to prevent rot and ensure your cuttings survive their first few weeks.

Method 1: Growing Begonias From Stem Cuttings

Stem cuttings are the most common way to propagate wax, cane-like, and tuberous begonias. This method uses a tip of the plant to create a new individual.

Step 1: Selecting the Stem

Look for a healthy, vigorous stem that is not currently in heavy bloom. While you can root a stem with flowers, the plant will spend its energy trying to maintain those flowers instead of growing roots. Choose a stem that is firm but not "woody" or brittle. A cutting that is 3 to 5 inches long is usually perfect.

Step 2: Making the Cut

Locate a "node" on the stem. A node is the bump where a leaf or branch attaches to the main stem. This is where the plant's growth cells are most concentrated. Use your clean tool to snip the stem just below a node.

Step 3: Preparing the Cutting

Remove the leaves from the bottom half of the cutting. You want a clean stem to insert into the soil. If there are any large leaves at the top, you can even cut them in half horizontally. This sounds strange, but it reduces the amount of water the leaf loses through evaporation while the plant has no roots to pull in new moisture.

Step 4: Planting

If you have rooting hormone—a powder or gel that encourages root growth—you can dip the end of the stem into it, though begonias often root just fine without it. Poke a hole in your moist medium with a pencil, insert the stem so at least one or two nodes are buried, and gently firm the soil around it.

Step 5: The Humidity Tent

Begonias love humidity. To keep the air around the cutting moist, you can place a clear plastic bag over the pot or use a plastic dome. Just make sure the plastic does not touch the leaves, as this can cause them to rot. Place the pot in a spot with bright, indirect light—never direct sun, which will cook the cutting inside the plastic.

Method 2: Growing From Leaf Cuttings

Rex and rhizomatous begonias are famous for their ability to grow entire new plants from just a single leaf. This is a fascinating process that feels almost like magic.

The Whole Leaf Method

For this approach, you take a healthy leaf and its attached stem (called a petiole). Trim the stem so it is about an inch long. Insert the stem into your moist medium at a slight angle until the base of the leaf is just touching the soil. Over time, tiny new plantlets will emerge from the point where the leaf meets the stem.

The Wedge Method

If you want to create many plants from a single leaf, you can use the wedge method.

1. Lay a healthy leaf flat on a clean surface.
2. Identify the major veins that radiate from the center of the leaf.
3. Cut the leaf into wedges, making sure each wedge has a piece of a major vein.
4. Insert the "point" of the wedge (the part with the vein) into the moist soil.
5. Provide high humidity and wait. New plants will grow from the cut vein.

What to do next:

• Select a healthy, colorful leaf.
• Prepare a small tray with moist perlite or seed mix.
• Place your wedges or whole leaves in the tray.
• Cover with a clear lid to lock in moisture.

Method 3: Water Propagation

Many gardeners prefer water propagation because it allows them to see the roots growing in real-time. This is particularly effective for wax begonias and Angel Wing varieties.

To do this, simply place your prepared stem cutting into a glass of clean, room-temperature water. Ensure that no leaves are submerged, as they will quickly decay. Change the water every few days to keep it fresh and oxygenated. Once the roots are about an inch long, you can carefully transplant the cutting into a pot with soil.

While water propagation is fun and visual, keep in mind that "water roots" are slightly different than "soil roots." When you move the plant to soil, it may take a week or two to adjust to its new environment. Be extra diligent with watering during this transition.

Caring for Your Young Begonia Cuttings

Once you have your cuttings tucked into their new homes, the goal is to provide consistent, gentle care. They do not need much, but they are sensitive to extremes.

Light

Cuttings need light to perform photosynthesis and create energy for root growth, but they cannot handle the heat of direct sunlight. A north or east-facing window is usually ideal. If you are using grow lights, keep them a few inches above the humidity dome and leave them on for about 12 to 14 hours a day.

Temperature

Begonias are tropical plants. They prefer temperatures between 65°F and 75°F. Avoid placing your cuttings near cold drafts from windows or the direct blast of a heater or air conditioner. Consistent warmth encourages faster rooting.

Moisture and Humidity

The medium should stay damp like a wrung-out sponge, but never soggy. If you see heavy beads of water dripping from the inside of your humidity tent, it may be too wet. Open the bag or lid for an hour a day to let some fresh air circulate. This helps prevent "damping off," a common fungal issue that causes young stems to collapse.

When to Pot Up Your Cuttings

Patience is a virtue in the garden. Most begonia cuttings will begin to develop roots within three to six weeks. You will know your stem cuttings are successful when you see new leaves beginning to grow at the top. For leaf cuttings, wait until the new plantlets are about an inch tall and have a few of their own leaves.

To check for roots on a stem cutting, you can give it a very gentle tug. If you feel resistance, it means roots have taken hold. At this point, you can gradually "harden off" the plants by removing the humidity tent for longer periods each day. Once they are adjusted to the normal humidity of your home, you can move them into their permanent containers.

Troubleshooting Common Issues

Even experienced gardeners run into hiccups now and then. If your cuttings are not thriving, it is usually due to one of three things:

• Mushy Stems: This is a sign of rot caused by too much water or a lack of airflow. If the base of the stem turns brown and soft, it is best to discard it, clean your container, and start over with fresh, drier medium.
• Wilting Leaves: This often happens if the humidity is too low. Ensure your humidity tent is sealed well. If you are propagating in water, make sure the stem is actually reaching the water.
• No Roots After Several Weeks: If the cutting looks healthy but isn't growing, it may just need more warmth or light. Try moving it to a slightly warmer spot or closer to your light source.

Propagating Tuberous Begonias

Tuberous begonias are slightly more specialized. While we often think of them as growing only from the tubers we ship from our facility in Lakewood, New Jersey, they can be multiplied via stem cuttings in the spring.

When your tuberous begonias have sprouted and the stems are about 3 or 4 inches tall, you can sometimes remove a "surplus" stem from the tuber. By rooting this stem in a sandy soil mix, you can create an entirely new plant that will even develop its own small tuber by the end of the growing season. This is a great way to make the most of your favorite varieties.

Creating a Beautiful Display

The ultimate goal of propagation is to create a more beautiful yard and garden. Because begonias come in so many shapes and sizes, the possibilities are endless. You can use your new wax begonias to fill in gaps in a shady border or group several rooted Angel Wing cuttings together in a large pot to create a dramatic, bushy focal point for your porch.

FAQ

Can I grow any begonia in just water?

Most fibrous-rooted and cane-like begonias, such as the Angel Wing variety, root very well in water. However, rhizomatous and Rex begonias, which are often propagated from leaves, usually perform better in a solid medium like perlite or seed starting mix. While water is an easy way to start, transitioning the plant to soil once roots are an inch long is necessary for the plant to get the nutrients it needs.

How long does it take for a begonia cutting to grow roots?

The timing depends on the variety and the environment, but most begonias will show signs of root growth within three to six weeks. Stem cuttings in water or warm soil often root the fastest, while leaf cuttings can take a bit longer to produce visible new plantlets. Keeping the cuttings in a warm spot with high humidity will significantly speed up the process.

Do I need to use rooting hormone for my begonias?

Rooting hormone is not strictly necessary for begonias, as they naturally contain high levels of the hormones needed to produce roots. However, using a rooting powder or gel can act as an "insurance policy," speeding up the process and providing a small amount of fungicide to help prevent rot. For beginners, it can be a helpful tool to ensure a higher success rate.

Why are the leaves on my begonia cuttings turning brown or mushy?

Mushy or browning leaves are almost always a sign of too much moisture or poor air circulation. If the leaves are touching the sides of a humidity dome or the surface of the soil, they can trap water and begin to decay. Make sure your medium is damp but not saturated, and try to give the cuttings a little bit of fresh air every day to keep the environment healthy.
