Atemoya scions on sugar-apple rootstock

[elriba]

I have been grafting various atemoya varieties onto sugar-apple rootstock.  PHet Pak Chong took almost immediately, but the other varieties have not.  I did two PPK, and both of them worked after about a week.

I am wondering if some atemoyas are not graft compatible with sugar apples, or maybe I am just a lousy grafter      Or both…

I am growing some cherimoya seeds to try on these.  About how long do I need to wait before I can use the cherimoya seedlings as rootstock?

Thanks

In my yard, about 1/2 of cherimoya seedlings, when started around March, are ready for grafting by November.

Plan on a year, perhaps a little longer.

For me its is a combination of getting a decent size and getting a good time (spring) to graft.  I will let the Cherimoya I start early this year grow a whole year before grafting to it.
That said, I have grafted to a few small seedlings but I prefer half pencil diameter thickness or larger for the root stock.

I recently grafted 7 varieties of atemayos to my big tree and PPC  were the first to take. Today I noticed the rest like super African pride and dr. White are beginning to sprout. Just be a little more patient.

I'm curious as to the location of your grafting and date.  The reason I ask is because I did 12 grafts of various atemoyas in the last days of February first few days of March. I used Cherimoya, Reticulata and Squamosa for rootstock. The two failed grafts where on squamosa. Not necessarily because of compatibility (I think) but because at that time my squamosa seedlings where dormant and not actively growing or just beginning to grow again. The bigger the rootstock the better the take.

I did these mid-march in Panama.   Sugar-apples don't go completely dormant in Panama, but during the dry season (which ends in April), they lose some leaves and growth is delayed.

Makes Sense. Thanks
