Wow I never expected to get a response like this.
I personally don’t graft at all myself. I want to learn one day, but I have a condition called an essential tremor. it just means my hands shake when unsupported or stressed so if I had a lot of scion wood to practice (and likely fail), I would try, but it will likely never be my thing.
While I can’t volunteer anyone to come help you, I don’t doubt there are several locals on the forum that would consider visiting Upakrik Farm and help you propagate the Patapsco persimmon. @scottfsmith is a wealth of knowledge who might know people that can help you continue the legacy. @hambone isn’t far away either. here is a map of local members in our community.
