Sabamiki_directing the growth of callus tissue to improve the appearance

-
This was the damage done by a caterpillar to one of my birch.  The entire chunk of trunk has passed through the digestive tract of the beast .  The remains of the trunk looked a bit strange - too weak to hold the mass of foliage I have planned to build.

August 2015


Luckily the birch was very keen to close this wound with a callus.  So I have decided to take an advantage of it and have tried to form an uro.   Using an adjusted piece of wood squeezed between both sides of  newly developed callus and fixed firmly to the trunk.

October 2019

This is how it looks like from the front:




And from the right side.
Nearly 3 cm of new wood added forming nicely shaped Uro.   Surely not very often seen on a birch but very happy with it :)

  Stupid or Greedy?   Well, why not both... For a good number of years I am planning to reduce the number of my trees.   And yes, some of them have gone, just to be fair with me.   Few of them left for free to my brothers in arms - bonsai enthusiasts and some of them via the European bonsai auction to bargain hunters. Sounds good, doesn't it? But at the same time I have started few projects ( seedlings cutting_Pinus nigra, Taxus cuspidata and Pinus parviflora_Zuisho cuttings, bought some interesting varieties of satsuki...   So at the end there is more leaves/needles than before.   And  NOT enough of that - I was about to give away a little mahaleb that was a honorable member of the Downsize club.  On the D day I have taken it from the shelf with the plan to let it go to some new place with more attentive hands.    I know this is the moment I should close my eyes and to armour my heart...  What do you think?   Neither of that was the case.   I have started to look on the tree from

 The first few days of the new year are a bit lazy. So why not to take the advantage of it and share some other trees? The mahaleb Zorro is one of my largest trees.  Well, better to say heaviest ones.  It is not very large, in fact it is just about 50 cm in height and about 70 cm in width.  But the trunk is quite massive and the pot needs to be quite large to accomodate the long surface root.   The shape  is not very typical for deciduous tree but I do like it that way.  And that counts...   Still long way to go...   The "new part" clashes with the old one - just looking like a baby's arse.  Not to mention  a better taper and finer ramification... Hope to find some time later on to repot it and while there to change the planting angle. The left side is right now planted too deep. Height: 50 cm Width:  70 cm Pot: China
