virginiana rootstock rejects kaki scion
I had an Evelyn persimmon that I decided to topwork last year. The tree is about one and one half inches in diameter, and growing vigorously. If I remember correctly, I grafted 3 or 4 kakis onto it last year. Most sprouted, then all died, and the rootstock grew more branches suitable for grafting.
This year I grafted 6 varieties onto it, 3 virginiana and 3 kaki. The 3 virginiana have taken and grown very well, one has 3 branches over 2' long.
Of the 3 kakis, one took, I re-grafted another with a fourth variety, and it took.
Then with only an inch or so of growth, they both died.
It seems to me that this particular rootstock will not grow kakis, and I am wondering if sometimes when a kaki graft fails on a virginiana rootstock, that the problem might be with the particular rootstock, and not with the graft union or the quality of the scion wood.
Anyone have similar experience?
