COFFEE WITH AN ARCHITECTTake a Breath, Relax — It's Just Design
Some prescriptions for some perspective, by an architect who has a hard time letting go
Full StoryAll the recent posts on grafting made me think I would throw this variation into the mix.
I don't have any pics right now, the drawing at bottom (left side) is the best I could find
The drawing does have several errors:
-when the scion is split (unequally) the thinner more flexible side comes down over the understock slope cut and then tucked UNDER the bark as a normal bark graft. Helps to put a small slope cut on the outside of scion to smooth the insertion and increase contact.
-the thicker half of the scion is cut back shorter and inserted at the top as you would any normal bark graft.
It's a relatively labor intensive graft which I almost never hear about. Sort of a combination of bark grafting and saddle grafting. I did a number of them last year in places where my understock was 2-3X larger diameter than my scion. The extra labor pays off on several levels:
-You get a LOT of cambium contact...nearly 100% of the scion's end grain heals in, which is rare with mis-matched caliper
-the grafts healed very fats and well, completely (or nearly so) healing over the cut understock within the first seaon.
-once callused, the graft is very well self supported. I have lost so many bark grafts to windstorms half way through summer....admittedly because I didn't provide some type of splint.
-the graft is visually smooth and clean...like W+T. I know this is just cosmetics but I like it!
Anyhow, just thought I would share a fun option for those who like to whittle scions.
