Propagate Begonia Stem Cuttings in water - Cane-like Angel Wing Begonia

Propagating by stem cuttings is just about the easiest way to make more begonias for next summer's garden. During the fall, I regularly trim off 3-node long cuttings and put them into the growing pots where they take root.

Now that cold weather has arrived, I root the stem cuttings in a vase of water. It's a great way to produce more pots of Begonias for next summer's garden.

Water the plant well the day before.

Take a cutting about 4-inches long, with 3 nodes, from a healthy stem.

Use a perfectly clean container. Rinse the container with a drop of bleach if you are uncertain about its spotlessness.

Remove all but the top leaf or two. There should be no leaves in the water.

The cutting should  have a healthy leaf node at the bottom. Don't leave a stub below the node. Place the cutting into the water, and place the container out of the sun. In a couple of weeks, you will see new roots beginning to form.
Check the water periodically to make sure it is still fresh. If it begins to smell, pour it out, clean the container, gently run water over the cuttings and put them in fresh water.

When the cuttings root, keep an eye on them. If they are left in water too long, the stem will rot.

Notice the long roots on the cutting on the right. Those little leaves grew under water!

Prepare planting pots by filling with potting soil. Make a hole with a pencil. I sprinkled some moisture retention crystals in the hole.

Water well and let the water drain out. The soil will settle when you water. You may have to remake the hole and add more soil.

Remove all but the top leaf or two from each cutting. Large leaves can be cut in half.

A few of these stem cuttings could or should be shorter, but they'll be OK. When they get settled in their pots and new growth emerges, I'll pinch it off to encourage branching and leafing out.

Even though their flowers are very pretty, Cane-like Begonias are grown mostly for their beautiful leaves. I keep pots on the kichen windowsill in the winter and in a shady seating area in the summer.

To keep your plants full and attractive, pinch off the top growth. Fertilize with half-strength houseplant fertilizer.

Nodes?....Nodes?,...explain nodes, I'm not some gardening genious but I've got this huge 4 foot baby that grew from a 10 inch dead-ish looking "thing" over the summer and people are screaming for babies off of it. I'd like to oblige them over the winter.

Nodes are where the leaves emerge. After the leaves fall off they are little bumps on the stem. Cut 6-inch pieces of those old stems with a node on the bottom of each piece. Stick them in water that covers the bottom two nodes and change the water regularly.
Plant in sterile potting soil when roots emerge.

Look at the photos here -

have you ever done this with dragonwing begonias?

Have you ever propagated dragonwing begonias?
I always cut mine at a node until A MONTH AGO when I read to leave about an inch below each node. Now I am anxious that I have wasted these new cuttings but I will still give them a chance. I have rooted cuttings from earlier so I am not bereft. Thanks for your good explanations and photos.

Hi - I'm back!
Begonia Gal - I propagate dragonwing begonias every year - in fact there are some stems in a vase in the photo. They are so easy!
Elizabeth - Where are you cutting the stems now? Is is working for you?
Looking forward to hearing back.

Thank you so much for the great info and photos. I have always loved begonias and usually have one or two hanging around my house! Right now I have an Angel Wing and a couple of those smaller ones that a lot of us buy for a spot of color in the summer. I have always been able to start cuttings from the Angel Wing very easily and quickly just in water. But, not the other smaller ones! (Sorry, I don't know their variety. The label just says "Bada Boom Scarlet". How could I resist?) But, every time I try to start a cutting from these, it either rots in the water or just does nothing in the soil! I was about to give up (which is not my nature at all) when I came across your web site. Now that I have some different pointers and new ideas, I will not be giving up, thanks to you! 😊 and I apologize for writing so much!

Nancy - I have found that the smaller begonias are easily propagated from a leaf placed on moist vermiculite and covered until the roots form.
Mill - I would plant those cuttings and keep them moist and away from direct light. Nothing to lose.
