Hey Bush2Beach, I've done 10 cleft grafts this Fall so far down in San Diego. They have been cherimoya on cherimoya grafts. Of those 10 grafts, 6 have taken, 2 definitely did not take, and I am still waiting on 2 more grafts. So my percentage of takes thus far could be as high as 80% or as low as 60%. An important side not, I sourced the rootstock from different places. I believe if my rootstock were my own, of size, and ready to go, the percentage of takes might be higher. The rootstock I acquired looked like some were actively growing but also some were not pushing new growth so I wonder if the latter made a difference.
