I am letting some cool spring breeze into the home today. The curtain knocked over my dragon wing begonia and plopped my plant upside down. It broke off 16" lengths-right up to the edge of the pot.
I have cut them with "bud nodes" and put them in tepid water for now.
Please advise me:
1. Should I let them "root" in water?
2. Should I "root" them in Pro-Mix seed starting soil?
3. Some other medium? If so, where can I purchase your recommendation?
4. Under a baggy?
I don't know what to do, and I have actually been putting off pruning this begonia due to lack of know how. So, now, I have to do something with it. I have really enjoyed this plant, and it has done quite well (slow, but well) in front of a big north window. The leaf shape is triangular and have two quite long ends and one short end. The leaves are quite red underneath and the flowers are reddish coral. If anyone knows the name of this plant, please tell me.
I will try to put a picture below.
First of all - that begonia is not a dragon wing. Perhaps it is Torch or something similar.
Second of all - not sure what your plan is on the cut leaves. If you are thinking of starting this cane by leaf cutting then you would be wasting your time. Just throw the cut off leaves in the compost heap. For each cane cutting you would want to trim off all the bottom leaves and keep the top 2 or 3 in place. If the leaves are quite long you can even trim those in half.
You can water root the canes but take care that the water does not "sour". You should check it daily and if it looks murky or smells then dump the water, clean the cup, and put fresh water in. An easier way is to put a baggie over the cuttings (change the water before you do to get rid of any germs) so you don't have to continue changing water.
Another way is to put the canes in a cup with perlite or potting mix (make sure it has drainage holes), water, then push the canes in past the first node or two (this is where the rooting takes place). Do not keep the soil sopping wet though but don't let it dry out completely either.
Last suggestion is to take the very long woody stems and cut the green stems off (use the green stems as suggested above). Get a tray and cut the woody stems to the same length (or less) of the tray. Put holes in the bottom of the tray, fill with perlite or potting mix, lay the stems horizontally on top of the mix, and water in. Each node should produce a new cane. You may want to lay some plastic wrap or lid on top until the new canes start pushing the plastic cover off.
Thank you, thank you, thank you! Very good instructions. A neat idea with the woody stem.
Now, I am curious as to what Begonia I have. Could you direct me to a location where I can Identify this Begonia? I bought it at the end of the season and it didn't have an ID tag.
