What are the chances of success for side veneer grafts on a loquat trunk in a situation where I plan to multigraft the loquat and keep (ie not cut off) the named, grafted growth above? In my particular case, I would like to side veneer graft maybe two varieties 1-2 feet up the tree (and below the lowest existing branches) on my 5' Champagne Loquat tree. I'd like to keep the rest of the growth above as Champagne - for now.
I HAVE already done one cleft graft in the small canopy thus far, but am I wrong to think these lower side veneers on the trunk would be preferable to continually cleft grafting higher and higher on the few laterals currently available - which don't even begin until about 3 - 4 feet up the trunk? Also, if what I propose is doable, how low on the trunk above soil line should I begin? Thanks to any/all for input you can offer!
