Cmeg1,

I don't think it's too late to defoliate. Boon had someone in his workshop defoliate a zelkova on Saturday.

Maybe try it on one or two of your trees.

I have defoliated my zelkova broom three times this summer. Each time, it responds with more and more back budding and tiny twigs!
Thanks for the nudge!I gave it a shot on one of them.I bet it sprouts.
Here is the pic.Also added a pic from start of season.
Thanks

When you defoliate a zelkova do you take the entire leaf out all the way to the tiny stem? Also I assume we are talking about entire defoliation and not just partial (ie. only the exterior leaves)?
I just took the nudge from Adair and tried it on one of mine. I cut it down to the tiny stem and had to be careful not to damage the buds.
It is somewhat of a partial,but practically complete.I left the smallest foliage on the inner parts as recommended in a magazine.I have seen full defoliation recommended in the same magazine too though.

Defoliated one more

I took a chance and Defoliated this one also.That makes two total.
Will be interesting to see how they turn out.
Here are pictures from start of season and then today,after defoliation.

12 days after defoliation.

This zelkova was defoliated for the first time 12 days ago.
I like the way it has budded and am excited for a nice Autumn with small leaves that I hope to color well.
Here is a before and after and also a video link.

Wow! It works!

Thanks,Adair.I am glad I tried it.Really gave me a sense of timing with the technique for these trees.We'll see how it looks by first of September after they have started to harden off a bit and I will maybe pinch a last time or so.

Next year start doing it a lot sooner. You can get 3 or 4 defoliations in, and have 4 times as many branches. Which is the name of the game with zelkova. You want lots of twig going, and good taper.

Zelkova 1 progress(or mistakes perhaps).

This tree was my favorite tree,I still like it,but I thought I would share the mistake I believe I made this year with it.
At the start of the season it was two years old and I was proud of the primaries I built.For some reason I decided to let it grow out when what I should of done is start defoliation around start of summer.
Though I was able to catch it in time and defoliate on 8/5/14.
It seems there is a time when you need to forget about primary branches and let shoots go longer to edge of a silouette.And defoliate a lot.
I am going to just keep filling in the canopy on this one.Probabaly would of looked better if I got three defoliations in this year.I love the short internodes I get after a defoliation.
Photos of late Winter, and on through the growing season.

Zelkova 11 progression

I am happy with this one.I got to experiment with defoliation for the first time.It is about 16 months old.I am going to take Adairs advice and defoliate a few times next season to get it twiggy.Who knows,it may need a bit of wire,maybe not.
Photos from last Autumn then through late winter and the rest of this season.

Moss on a training plant

Any reason to have moss growing on a plant that is still in development?

Hi,TX.Yes the picture of the colander is kind of misleading.There are inverted clay saucers in them and the trees are only in about 1" of soil.I actually feared them drying out while I am at work.So I thought the moss was a good solution.

Both of these will need to be cut back this winter. After the V, there's little taper. Gotta have taper.

Search through Jonas' blog, Bonsai Tonight. There was a post within the past couple months of a garden he visited last winter, where there were hundreds (if not thousands) of zelkovas about the size of yours that were tied up for the winter. Some were tied up with zip ties. To bring that V in tighter. You don't want a wide V nor a U.

Your little trees are progressing, and it appears you are really learning from the process! And since you start new ones each year, they're getting better and better each year!

Keep it up! You're doing great!

Yes thanks,Adair.
I do look forward to the winter trimming.The buds are always plump and everywhere at the end of Winter storage.
I do plan to start yet ten more from seed next spring.I had a horrible batch of seeds this year,so that is why I made the 18 cuttings.They are for clump style.
I am going to visit the local park this autumn and get seeds from the many Zelkova trees that are growing.That seems the best way to get viable seed.
Thanks again!

Dont you want to fatten them before defoliation? Defoliation slows them down...
I tried an experiment byt removing the lower leaves and leaving only the tips....versus trees which were left to grow...the internodes drastically reduse if you remove the leaves.

Hi,Neli.I actually did want to fatten them at the start of the season.And I did use the technique of only leaving leaves at the tips of sacrifice growth.Great technique,thanks.
Looking back at this photo at the start of the season when they were approaching a year,I often wonder if I should of started defoliation right away.I was happy with the image on most of the trees.
All is not lost though,as you can see in the following post.The trees did fatten up a bit and the shape can be regained with guy wires and such.Then I am going to defoliate next season and try to put some canopy's on these trees.

The trees I did not defoliate

I have around ten of these 16 month trees.I made the decision to prune to shape this Autumn and Winter and apply guy wires and such to bring the branches back into -V - shapes,not L's as Adair has pointed out.
I am quite happy with these.They have the bones to make some nice brooms next season.I am going to defoliate as much as possible and try to put some canopy's on them too.We'll see about that.
Thanks,Adair and Brian too for the guy wire technique from his blog.
8" colanders and a standard brick for size reference.

My first canopy.....kinda'

This tree popped out at me today,so I shortened the larger leaves down to 2/3 their original size on the more vigorous side of the tree and it evened it out some and resembled a real canopy.My first.
It should only get better from now on and steadily get more uniform.It also gave me hope for the rest of my zelkova's.
Freshly defoliated less than a month ago,it is nice having fresh new leaves this late in the growing season.
I do not expect too much more growth as I am starting Autumn fertilization 1st of September.
Here are the photos and also a video link for 3-D.

Windy day, huh?

Looking good!

Here are some tips for cutting back: When you cut back, cut back to 2 leaves. This will remove most of the big leaves, keeping the smaller ones. You should get new sprouts from the base of each remaining leaf, increasing density. They also have shorter internodes.

Then, when you do want to make a leaf smaller, there's a technique to make them not look so "chopped off". Kinda tedious, though. Fold each leaf you want to make smaller in half, along the center vein. Then cut the folded leaf back on the diagonal. This makes a shorter pointed leaf.

Yes,thanks.It was a breezy day yesterday.Has been a rather cool Summer,only one day that I know of that approached 100.We usually have several heat index days,but not this Summer.
Thanks for the leaf tip,I knew I was forgetting something.That will look nicer.
