Title: Chip budding

Derry,

 

The rootstock I'm using is B-9.  The trees have been benchgrafted, received and plant in a portion of my garden in May.  I intent to transplant them to their permanent site later this fall.  The union varies from 4 to 7 inches above the ground.  I wasn't concerned about height yet since they will be transplanted later this year.  When you say 2 to 3" above where the new growth started meaning above the shoot that sprouted from the rootstock?  Since the scion portion didn't take, I allowed one bud to break and grow on the rootstock to provide it nourishment in the event that I would perform surgery/grafting on the rootstock later. 

 

My question to you is, when I do finally transplant the seedlings to their new home this fall, how much above the ground should the graft union be, assuming I wish to achieve a full dwarfing tree that this rootstock is capable of.  Is there a recommended height to plant this at..? 

 

Thanks again to you and Ed for your help,

 

Brian

Brian,

 

Definitely take Ed Fackler up on his offer ... you must live just outside of his heaven!!

 

I bud into this year's wood about 6" from the ground.  I try not put the new bud exactly where the growth started this year because there will be a lot of auxin in that area, but 2 or 3" above where the new growth started should be fine and 4 or 5" will be even better.

 

You didn't mention what the rootstock was ... dwarfing?   Remember that the higher the graft, the more dwarf the tree

 

If you do a chip bud, the bark of the rootstock will more closely match the bark of the bud you are putting on and you can make a better match of cambium to cambium.    

 

Now if your new growth is really whippy and furry i.e. result of rapid growth in last couple of months, you may be better off going into old wood.

 

What type of graft was the first one?     bud?  whip and tongue?

 

How far from ground?

Yes, the new growth is about 2 feet and more.  I take it, then, by your question that I would be grafting on this years' wood rather that the older wood that the benchgrafts were grafted onto.  It would seem to me, though, that the new growth would be extremely fragile to cut into.
