@LorettaNJ I'll be sure to update the thread if there's anything happening! I hope it's not anti-climactic. I've only had success propogating succulents and pothos, and a couple of the begonia cuttings are already losing leaves.
Yes, I did read about the little bulbs and see them on the plants.
@Adriennevs Haha! You just type "@" followed by the person's screen name. Thank you so much for your input and suggestions.
Wow, I had no idea how many begonias are available and the love that people have for them! I didn't know what they were until someone told me the "weed" I've been pulling in my garden is hardy begonia. I'm the worst.
Now, I think they're really pretty and interesting. So, the technique I used with the rocks and the plastic wrap I found in this video by this adorable Irish lady.
