Today’s update is a fun little English Elm that was styled last season. Post on that styling below:
Today’s work was a fairly simple repotting into a lovely Koyo pot. I really love these pots and am always happy to use them with my trees.
The tree is probably ready for a re-wire but as English elms are one of the later trees to leaf out I will try to squeeze that in between repotting my remaining trees and bud burst.
I really like this lumpy little tree. its a bit ugly and has some strange bumps but I think that they all add to its character. I recently sold its brother to a friend so i will likely be hanging onto this tree for a long time.
I have begun to re-pot some of my deciduous bonsai. I like to re-pot my pines closer to spring time so I do my deciduous species a little earlier in order to leave plenty of time for the conifers.
The tree in today’s post is an English Elm (Ulmus procera). I picked it up at a local bonsai show last year. I have always liked clump style bonsai and am always on the lookout for suitable stock (which is quite hard to find). When I saw this little clump I quickly grabbed it.
The Elm after a year in my care.
Since owning it, I have fed, pruned and wired a little. It proved to be a very strong grower so I defoliated 3 times during the growing season. After the 3rd time it did not bud out as strongly as I would have liked which means I will only do two defoliations this coming season.
As the tree had been in a rather large terracotta pot it had developed a large rootball, as a result a fair amount had to be pruned off in order to get it into a bonsai pot.

This re-potting I concentrated on removing all downward growing roots. This lead to a large percentage of the rootball being removed. Although Elms are strong trees I thought that I would not prune the surface roots as much as I might otherwise due to the large amount I had already removed from the rootball.

As you can see from the above image there are a number of large un-tapered roots. In the next re-potting I will be looking to reduce these roots to introduce some taper and delicacy to the rootbase. For the time being though, these roots will help the tree recover from the loss of the larger part of its previous rootmass.
If you read my post “Two pots” you will be familiar with the two pot options I had for this tree.
The two pots I had to choose from.
Although I like both choices I ended up chosing the left hand pot. What i found interesting was how each pot gave the tree a different feeling. The left pot (Yamafusa ) gave the tree a more spreading feeling while I felt that the right pot (Ina Genzou ) made the clump appear much taller. The beauty of liking both the pot/tree combinations is that I will happily alternate which pot I use in future re-pottings to give the clump a new feel each year.
The prepared pot (minus tie-in wires)
For its size the Yamafusa pot had a good number of drainage holes, each of which needed mesh screening to prevent the soil media falling out and to prevent some of the larger pests getting in.

The Elm was then tied in firmly and soil worked in around the rootball. I feel the pot is a good fit to the clump and the green of the pot should work very well with the yellow autumn colours I hope to get next year. This clump has a long way to go before it is a good bonsai but it is now firmly on its way. Hopefully heavy feeding combined with defoliation will add a fair amount of twiggyness and branching to the tree to further enhance its image.
