Melted wood?? Yes, melted wood. How else do you describe this hunk of mountain hemlock below? As the Covid-19 virus spreads around me here in Seattle, I have some extra time to also call the melted mountain hemlock below the subject for this week's Throwback Thursday. Today's post is short, so if you're curious about

how a tree can become as mangled as this one, read on.





From this view, we can appreciate some of Dan's deadwood carving, which starts to look more natural as it naturally weathers over time.





Returning readers may guess correctly that this tree is one of the many beautiful yamadori (mountain/wild trees) collected and styled by Dan Robinson , on display at Elandan Gardens . This throwback is timely as I can use it to remind you, dear readers, that we are in the peak of the repotting season in Seattle right now!

Next week I promise to have a more thorough repotting tutorial for all you beginners out there.





Below you see our subject before the repot operation. The pot has begun to fall apart or "delaminate" after years of exposure to cold (it may not have been a high-quality pot, as some clays fired at higher temperatures hold up fine for decades). Here you can prominently see that there is several inches of soil above the lip of the pot before we reach our trunk. In this repotting session, we worked to reduce that unnecessary height to fit the tree into a smaller pot.

Below again you can see the melty hemlock before we took any action. You can see the tree is very healthy!

Hemlocks become bushy with little effort. This tree will no doubt recover from our root pruning quickly. In the above and below pictures, you can also tell our hemlock bonsai has a young volunteer azalea

in the pot. Now it's more like a Chinese penjing landscape!

Above you can see also see some of the fine white root tips in the pot. These "fine feeder roots" are the powerhouse of our bonsai's root system. They import all the water and nutrients that sustain the rest of the tree. We will be sure to leave plenty of them on our tree once we are finished to ensure it recovers easily.

Below you can see several views of our finished tree in its new home! We began by working our way through the top layer of soil in search of major structural roots that could add to the nebari (the Japanese term for surface roots). In doing so, we managed to reveal an extra few inches of snakey trunk folded onto itself.

As you can imagine based on the fact that you don't see trees like this around your city block, this sort of structure to a tree is highly unusual. Most naturally formed bonsai trees (yamadori) are naturally stunted because they exist in an extreme environment. This tree came out of an intersection of

extreme environments - a highly acidic bog AND a mountainous area with heavy snow loading. Canada really is magical, if you can hack it through the government bureaucracy to bring live plants back over the border that is. The acidity of the soil does the work of slowing growth by inhibiting the uptake of Nitrate and other essential nutrients. The wetness does the work of limiting the space that roots can occupy to grow as the roots of a normally land-dwelling species would drown themselves if they stray too far into the water. And lastly, the heavy snow load did the work of bending the leading trunk or branch which became the leading trunk down on the old trunk. This is the power of naturally formed bonsai. A whole life story that spans centuries all told in one pot by the evidence of the trunk and the deadwood and the remaining branches.
