I have been grafting my AM persimmon rootstocks the last couple of days. I have had hits and misses with grafting them. Is now a good time? What do you think?
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.
John: I opened up my big green binder and found copies I forgot to get to you, so I spoke too soon and therefore no need to respond for the first persimmon papers question. (sorry)
As it is I did find the same person's PDF document online and with much more help than my paper copy so just google fruitbook9.pdf then on page 25 you will find a pointer #3 (persimmons) under the heading "How Soon After Transplant Can I Graft?"
(ie. #3: Some plants do not transplant easily and will need a full year to recover from transplant for grafting. These plants include persimmons, pawpaws, and pecans)
