I have some tame mayhaw trees but I know nothing about getting the scions. I am familiar with camellia scions.
Tell me what to do and I'll send some to you and tell me when to gather them.

Florence,

Sorry, I haven't looked at this site for a while. Good scion wood for whip-and-tounge grafting is obtained from the current years growth.
Usually between 3/8" and 1/2" in diameter. You collect the scion wood, (at least with deciduous plants), when the plant is dormant. With mayhaws, that would be during the winter...I'd collect the wood during early February.
You can send me an email at the following address:

Thanks...
