Birch from high altitude
« on: July 22, 2012, 03:58 PM »
Hi All,

This is a birch that I recently got from a flat roof that was going to be renovated.
It was the beginning of June and the tree had much more foliage than it has now. The rootspread was incredible. It was well over 4 m2, under the insulation on that roof. The insulation was pushed up as good three inches, the thickness of the roots. Although it was high summer, I needed to have it and I needed to get into my car with as much roots as possible. I managed to get about 2 m2 of rootmass in the back of my car and drove home. I selected as much fibrous roots near the base and managed to bend more flexible roots so that the fibrous roots were near the base.
In order to make it survive a lot of foliage had to go.
Now, about 6 weeks later, its growing and I fertilized it with a low dose of chemical fertilizer.

It will be at least another full growing season in its container. After that I hope to be able to work the roots.

Obviously it's going to be a multitrunk bonsai. With 5 of 7 trunks. Should be possible in 4 to 5 years to get a basic structure.
Preserving the deadwood might be a problem. Anyone ideas about this?

The main trunk is likely going to rot.  What does the view 180 degrees from the sticker look like?

Hi Owen.

This view looks good to me.  I think a 7-13 trunk clump would be nice.  They do "shed" branches, but they will stay a long time if they get good light.  Maybe partially destroy the main trunk and include in design.  It would look real.  The fun part will be spacing out the trunks  ;).

Thanks for your reply Owen.

Yes I'm looking forward to selecting and placing future trees/stems! I hope the old stumps remain long enough so I can include them, with some carving in the design.

Last week I worked on my birch clump again.
Cleaned up a lot of dead small shoots and branches and wired 9 shoots in place.

The clump starts to rot allready: there were a lot of elves benches on the old trunks.
My plan is to let the shoots/stems/trees grow as fast as possible next summer, and then bring some shape in the remaining deadwood.

I've seen wood-hardeners and jin-seal.
Would this be appropriate to stop the rot?

A quick follow up on my birch. Last pics were three years ago.

The old trunks are all gone.  The remaining wood is firm and forming callus.
It was repotted last month.  The big roots that were folded into the pot after  colecting are removed.
I will let it grow free for another year to thicken the trunks a little more. Final hight of the tallest trunk will be around 30 cm. Hight now is way over one meter.
Like v to hear your suggestions.

It is really good how the tree has progressed in 3 years.  Definitely think you are on the right track there.

Well done.
