Here's my C. ovata 'Gollum' I have been training. I have used a combination of selective pruning and wiring, along with leave removal to get this upright/cascade look. I can't find images from many years ago when I first got it but here a few over the last couple years as it had begun progressing.
I also repotted it into a tall skinny pot a few years ago to get it to develop deeper roots to get it ready for cascade bonsai pots that way I do not have a succulent in a deep pot with only surface roots. And to slow me to start bringing down the cascade branch
Here's it after a growth period of about a year, I let it fill in. This was March 4th 2019
Here's it around 8 months later
And here's it today.
It will be repotted into this small cascade bonsai pot this week
As you can see I have been slowly able to bring the cascade branch down lower and lower. It's a slow process as jades like to break rather than bend like trees will do when training.
