Does anyone out there know how to do this? I'm willing to pay someone who can do these things to assist me with my fledgling black walnut farm. I have a couple of trees that I think produce pretty special nuts, including the largest nuts I know of from reading the literature, and I want to have scionwood from the mother trees, about 70 years old, grafted onto young field stock.

Does anyone know someone near Ann Arbor Michigan who could do this for me?

To be clear ... you are interested in NUT production as opposed to simply timber production?

There is an extensive black walnut grafting program on black walnut plantation between East Jordan and Boyne City in northwest lower Michigan.  I can give you the name of a retired general surgeon who has been grafting black walnut for a couple of decades with excellent graft success.  This fellow is 92 years old, but going strong and is the best grafter I presently know.

In my opinion, this grafting MAY be valuable for nut production but is almost useless for producing timber type trees.

Is your superior mother tree a heavy and reliable producer?  Can you post or send pictures of the mother tree.  Full view and close up to illustrate nut production pattern?

How tall is the mother?  I ask because the best scion wood for grafting is likely to be high on the tree and difficult to gather.

Send me a PM or contact me at vinekeeper@forestfarm.org for contact information.  The effort "up north" consists of several thousand black walnut seedlings grown for future timber production.

I have grafted black walnut scion wood with success. I have done the bark inlay graft and the whip and tongue graft and they both worked. Success rate is pretty low so graft a whole bunch of stock. There is some prep work to do for bark inlay graft, such as cutting the trees a week or so ahead of time to let the sap run. Purdue and Missouri have some extension bulletins referring to black walnut grafting. You need to be careful how you collect the scion wood.

Yes, nut production. This tree produces massive walnuts that seem to be larger than the top end of the ranges I have found published in literature or on line. Only been watching the mother and paying attention for three years. It looks like she produces every other year, with some blanks in off years.

I will get some useful images this weekend. Not home right now.

The mother is about 70 feet tall and I know she was planted in the early fifties by a friend of mine. I have another friend who is an arborist 👍🏽
