Persimmon depends more than anything on elapsed time when last transplanted. Remember the educationals that I handed you that were stapled together at our last scion exchange? They were my favorites of all favorite few articles some of which classed the more difficult fruits to graft (ie. persimmons). I had hoped it would be kind of a cheat sheet to you at your booth, and no, I never grafted persimmons my whole life. They recover from transplant shock very slowly compared to others and need more time to be happy about being grafted upon. The scion couldn't care less as in the case of whip and tongue because they will always be dormant.

On another note, I sure could use some fungal compost tea at this point for pear rust. Please shoot me a PM note if your brewing any. I could pay. My strain of pyrus betulafolia had been crossed by pollen of malus baccata with lots of work and a good set in these California like conditions and at this point rust is threatening to kill all the fruits.
