Hi Mario,
These trees are very hardy, they survived NY coldest winters a few years ago, also survived Super Storm Sandy, around 4ft in the back yard.
I have learned that it is nearly impossible to root cuttings from this because the clippings are very dry and woody. I have tried several times with no success and an old timer gets a chuckle when he comes over and see what I am trying to do. lol
I have now two trees, this was a very bad year as most of my fruit dropped, its been drought like conditions in this part, perhaps that has something to do with it??
I know Pino was also interested, but unless you know that it can be done some other way? I can send you some, I think Spring is the only time to make an attemp.
