A few years ago I read a story about a ancient japanes Sakura tree around 1000 years old that had begun to decline around 100 years ago. As it was a national treasure and upon the request of the emperor of Japan they took cuttings from the tree and grew many mature trees for the purpose of root grafting. A few springs later they dug trenches around the roots and grafted on many young cherries roots. The tree began to thrive again.
So I was thinking about species and vigor in general in regards to my possible move to the west coast. Could you take say a old ponderosa and graft japanes black pine roots onto it? Would it become more heat tolerant by doing this? Would grafting black pine foliage onto a ponderosa give it the heat tolerance of black pine? If so why not graft trident roots onto Japanese maples for better vigor? I would think of techniques like this were possible we'd be doing a lot more of it... After all no one ever sees a well done root graft as its below the soil line.
