How does the begonia reproduce?

How does the begonia reproduce?

A particular group of begonias, called the rex begonias (Begonia rex cultorum), propagate themselves through leaf cuttings. Unlike other plants that use specific stem portions for reproduction, the rex begonia uses its leaf veins to create new plantlets. The plant thrives outdoors in warmer Mediterranean climates.

Can I split begonia corms?

Begonia tubers increase in size each year and after three years or so, the flower display will begin to deteriorate. It’s best to divide the tubers in the early spring, after the buds have begun to swell. Use a sharp knife and divide into as many pieces as you like, as long as each piece has at least one bud on it.

What type of propagation is begonia?

leaf cuttings
Propagating begonias is actually quite simple and easy. This can be done by tip cutting, by rhizome, or by leaf cuttings. Rooting tips (the plant tops) is simple, and can be done in much the same way as rooting tip cuttings for other plants (see, for example, the lesson on kohleria).

Do begonias need nodes to propagate?

No need to use a soilless mix and rooting hormone, these plants want to grow. You can start them in a glass of water. Keep the begonia cut stems cool and moist until you get them into a clear vase or jar of water. You want as strong a piece of stem as you can find with at least 2-3 nodes (joints).

What is a leaf node on a begonia?

On a begonia stem, there is a node above each leaf. This node can have a bud that will grow into a new stem someday, a flower cluser or remain dormant. Any node that doesn’t have flowers or the scar left after the flowers have fallen off, has a bud inside.

What causes begonias to rot?

Caused by the Pythium ultimum bacteria that becomes activated in wet soil conditions, begonia stem rot is usually fatal to the plant. Keep the risk to your plants low by ensuring your soil is well-draining and that you do not overwater.

How do you multiply begonia tubers?

Begonia tubers can be forced to propagate by dividing stem and tuber cuttings and will propagate on their own by seeding and by naturalization in the landscape. Even under the best circumstances, begonias can be finicky to propagate and the failure rate can be quite high.

How do you split large begonia tubers?

How to split the tubers

1. Step 1 – Find a suitable tuber. A tuber ready to divide should be large and also have at least two clear stems.
2. Step 2 – Cut with a sharp knife. Cut the tuber with a sharp knife directly between the two stems.
3. Step 3 – Leave to dry.
4. Step 4 – Replant.

How do you keep begonias from getting leggy?

Pinching and Pruning Pinching back your begonias is the first step to correct legginess. For small plants on windowsills, or seedlings for the garden, pinching out the tiny new leaves on the growing tips of the begonias will force new growth along the stem and encourage dense, compact plants.

Can you start a begonia from a cutting?

You can grow begonias from seed, but it’s much easier to propagate them from cuttings instead, and you can do this with most kinds of begonias. To make babies from cuttings, start by snipping a few healthy leaves from your favorite begonia. You can get a lot of baby plants with this method.

What does an overwatered begonia look like?

Look for the following symptoms and conditions that make it more likely that overwatering is the cause of your begonia drooping; Yellowing leaves, particularly affecting the lower leaves first. Brown leaf tips despite good humidity and soil moisture. Leaves dropping from the plant, often with soggy, limp petioles.
