Threadgrafting _modifications of standard technique  ( part 2 )
I know. I have promissed.
And I have missed it.
No excuse.  OR?

I have spent the last few days just rambling in the vicinity of the place I live  as the weather was great..  

 Just a poor excuse to cover the  fact that I HAD A GREAT TIME

Please fell free to enjoy  with me...

One of my maples (Acer pseudoplatanus) in early morning  sunshine



How many colours can you see?  One of my favourite spot.  Just behind the slope there is Prague...

In fact I was not the only one who took a break to enjoy the warm autumn sunrays.  A crowd of firebugs  Pyrrhocoris apterus in the insect private sun spa...




Well, back on the horsebacks now ...

In this part of the article I am going to cover the so called OPEN THREADGRAFT and  THE TWO WITH ONE Threadgraft

OPEN THREADGRAFT

This is a method that combines an approach graft with a threadgraft and can be used later in the season  BUT it is limited to the grafted branches that are not too thick so you can bend them.

  1. Drill a hole in the grafted branch with a drill bit that has the same diameter as the graft
  2. Make a cut that connects the surface of the grafted branch with the hole.
  3. Bend the grafted branch so the cut will open 
  4. Insert the graft ( with revealed cambium all over its circuit ) through the open slit to the hole
  5. Close and  seal with a grafting tape

With this technique you can get a much bigger area where the cambiums of the graft and the grafted branch get into the contact ( similar to the approach graft ). And in the same time you will get better position of the graft on the grafted branch.

  TWO WITH ONE   

Two branches/roots with a single threadgraft

A standard threadgraft. You only need to plan the position of the threadgrafting hole so the new branches/roots are in the required position. Easy.

  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?...

Prunus mahaleb_Zorro

 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
