Threadgrafting _modifications of standard technique ( part 2 )

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.
