One thing I can add from the house plant forum. Make sure when you make your cut, do it at a leaf node going in the direction you want your plant to grow. Ex. if you want your original plant to grow out, cut above a leaf growing out. If you want your plant to grow to the right cut above a leaf pointing right. I prune my angel wing all the time and at first i didn't practice directional pruning and the growths went everywhere. Jack

Oh. Thanks Jack, I never would have thought of that.

Mrs B, there are many methods of rooting cane begonia cuttings and every propagator has a system of their own.

The easiest way to root the cuttings is to simply put them in water. Take a 4 to 6 inch tip cutting, cut off the bottom few leaves and leave several at the top. Put it in a glass of water, a situation on a bright but shady windowsill is fine. You should see roots in 3 to 6 weeks depending on your conditions. Once some good roots have formed, plant in your regular growing mix and keep it moist but not wet.

If you want to root in a potting medium....

Take tip cuttings about 4 or 5 inches long. I cut the lower leaves off the bottom half of the cutting and leave several at the top, but if the leaves are very large they can lose too much moisture and cause the cutting to wilt, so I cut large leaves in half across the width. Put the cutting into a potting mix, I prefer a soilless mix of peat, perlite and vermiculite but any light, peat-based mix is fine. Don't use the heavy, dirt-type mediums erroneously sold as 'potting soil'.

Cane begonia cuttings will root in a greenhouse or shadehouse in Florida with it's high humidity, but you may need to place your pot with the cutting into a clear plastic bag or some other kind of enclosure that will hold humidity. If you find the cutting wilted, you will need more humidity and it requires bagging or another enclosure. But put the cutting into water to rehydrate before putting it back into the pot and into an enclosure.

This might be clear as mud, so if I'm not clear on some points be sure to ask for clarification. There are many other begonia growers here that may also have suggestions.

A technical point here... before you take your tip cutting, be sure the base plant below your cut point is capable of branching. You mentioned your plant has been blooming, and most canes cannot branch at a node where it has bloomed. The nodes either produce a dormant bud or a bloom, but usually not both. So, look for a little spike at the nodes where the leaf joins the stem. These are dormant buds where the stem can branch. If the stem below where you're going to cut has these buds, you are fine and you can take the tip cutting.

I do in fact see one of these little spikes in the first large pic you posted above.

Hello you can propagate your begonia by leaf if you wish to watch a video about leaf propagation of a begonia please watch https://youtu.be/KQu_H3Yroa0 Thanks all

James, this thread is about cane begonias and they can't be propagated from leaves. Maybe a technical exception or two but I don't know about them. But a video of how to propagate rhizomatous types from leaves might be really helpful to some just tuning in here. Thanks!
