[nafex] Re: Important detail on bridge grafting

Thanks Hélène.

I'm the disappointed grafter.  Thanks for the extra tip.

What I can't decide is whether to attempt more bridge grafting, or to 
encourage growth from below the damage, to recreate the tree 
structure since the one attempt (at 3 grafts) just ended in 
frustration and a botched job on my part.  I'm leaning toward 
the "encourage growth from below the damage" as I've limited time and 
I feel my chance of success to be low [for the bridge graft].

Since I'm in a one tree of each variety situation, I have taken the 
step of taking scion wood of each of the damaged varieties 
and "banking" it on the standard size Stayman Winesap I've been 
pruning down to a manageable size.  My eventual goal on the Winesap 
is to have it produce no Winesap apples.

too long. But the curve creates a tension which keep the limb in 
place under the bark at both ends and a good contact.

each end and later the limb which now carries the cadmium accross the 
gap also gets wider and stronger.
