The basics of fall work on ume are straightforward: remove the old leaves and prune to silhouette and/or the desired internode length.
Before removing the leaves – no signs of fall color
Fall has been mild this year so the leaves remained healthy into December. By removing the leaves, I could better see what branches had grown since I last pruned the tree in spring.
After removing the leaves
Although it’s hard to see from the photos, I made a lot of cuts to remove dead branches and stubs. I also shortened the relatively small number of branches that extended beyond the desired silhouette.
After cutback – 16″
When I finished the pruning, I applied cut paste to the wounds and returned the tree to the bench.
For a reminder of the progress the tree has made over the years, I dug up a photo from when I first planted it at this angle in 2015.
Establishing the current planting angle in 2015
This, of course, reminded me of how the tree used to look. Here’s a shot from 2003 when the tree was grafted with branches that produced white flowers.
2003 when all three trunks were still alive
Going further back, here’s a photo of the tree after I wired it for the first time.
1994(ish) – initial styling
I was about a year or two into bonsai when I acquired the tree as part of a workshop with Kathy Shaner. The tree was field grown by George Muranaka and sourced for the class by Max Cooperstein.
About a year later, I removed all of the branches and grafted new foliage as I prefer white single flowers to double pinks. I kept the tree that way for several years until two of the three trunks died. That’s when I turned the tree on its side, selected a semi-cascade form for it, and began training the remaining branches.
Over the next few years I’ll aim to improve the branch density on the lower branches in hopes of showing it, when it’s ready, in a winter exhibit.

Hi Jonas, I thought there was a small ‘window’ for fall pruning? Also could you share and article about changing deciduous foliage? Do you do it in stages having both varieties at some point?I have got a shishi maple grafted on a mountain maple trunk which I will like to change for another variety perhaps Deshojo.
Thank you for sharing.
Jonas Dupuich says
Hi Paolo! The window is to prune before the tree goes fully dormant. Since the leaves were still green when I removed them, I’m well within this window. (It doesn’t always get cold enough for my trees to go fully dormant in winter.)
As for the changing deciduous foliage, that’s a good idea for a topic. In general, I treat each graft separately. Once I have enough total grafts to support the future branches I want to develop, I can remove the old foliage.

Hi Jonas, do you know why 2 of 3 trunks died at some point? Or any hypothesis? (in case you already answered to this question and i missed it, sorry)
Jonas Dupuich says
It appeared to be a fungal pathogen – several trees in my area were affected the same year. I didn’t send it to a lab so I don’t know the exact culprit.
Neo says
how do u know that the plant is still alive ? i’m a noob
Jonas Dupuich says
The tree is deciduous, it loses its leaves in fall and they regrow in spring. This year I removed the leaves to force the tree to briefly go dormant.

Hi Jonas,
May I ask you what is the best period for repotting Prunus mume?
Where I live (Italy) it usually flowers on February 15/20.
I was thinking of repotting it a month before and keeping it protected from the weather and the intense cold that could come in February.
What do you think about it?
My compliments for your work and your site!
Jonas Dupuich says
Hi Saverio, thanks for the note! I usually repot ume just before they flower when the buds start to swell. Repotting a bit early, if you protect the roots, sounds like it wouldn’t be a problem.
I don’t know if repotting before flowering has an effect on the flowers. You’ll have to let us know how it goes!
