I like to share another progression of one of my trees. Its a Zelkova Serrata, THE classic species for a Hokidachi, or broomstyle.
The story started in 2010, when I saw a 'normal' young Zelkova tree in a local gardencenter. It was about one meter in height and the trunk was about 2-3 cm in diameter. The nebari of that tree was bad, so I decided to place a marcot.
In 2011 I separated the upper part from the lower part. Unfortunately I have no pictures of the tree that time, but the marcot had developed roots at all directions of the trunk. I placed it in a big pot to strengthen the fresh roots.
The Hokidachi style tree I wanted to make couldn't become too high, because of the thickness of the trunk; 45cm in height for the finished tree was a nice size in my opinion. The ideal trunk height for this style has a ratio of 1 to 3, so I chopped the trunk at a height of 15 cm. I did that one year later, in 2012.
2013- New shoot were formed, and I selected 2 to become stronger. I also wired the base of the shoots to minimalise the expanding of the outer part of the base of the shoots.
Here the trunk in 2014, after the first prune.
