3g Soursop Guanabana tree graft on Cherimoya rootstock

[Tony714]

Hi,

I have 3g soursop guanabana grafted on Cherimoya rootstock. It's 3+ feet tall and ready to uppot. Please note Soursop Guanabana graft comes from UNFRUITED tree. 
Pick up inly in fountain valley and asking for $90.

Thank you for looking

Hate to say this, but the soursop graft may die when the cherimoya goes into dormancy. The soursop needs to keep growing. I've had numerous other anonna species die on cherimoya rootstock ie: Montaņa, Rollinias, Soursop, Pond Apple, and neolaurifolia. I have no problem with squamosa and reticulata.

Thanks for the tip. I have a rollinia survivor over winter dormancy on atemoya rootstock.

Yeah, Atemoya rootstock is better with those "harder" species. I have had luck also with Atemoya.

Last year was fine.  I'll see this year.

Good luck. I take everyone's experience with a grain of salt. There are a lot of moving parts and farming can be nonlinear to human activities. It can be pretty tough sometimes to pinpoint where it went wrong. Everyone's geological setting is slightly different, which can cause varying results with rootstock-scion interactions. Apparently at Mark Lee's location, the scions can't survive past dormancy. It can't hurt to try. I've had canistel grafts not make it past winter dormancy either but the seedlings keep on trucking ..

Yes, it depends on many things. Some cherimoya do not go into a full dormancy where I'm at. Right now I have Annona Montaņa grafted on cherimoya and we'll see if they make it through the winter. The main tree is fine outside and has fruit, the tree didn't suffer any damage.

Mark, so if I have a large cherimoya tree that doesn't go into dormancy then would a grafted soursop survive in my area?
I have a seedling soursop (for 3yrs) and it keeps dying back every winter and then comes back about April, so can I graft it to my large cherimoya that never goes dormant, and would the soursop have a better chance of growing more than 3-4 ft each year before dying back to 1 ft?

Tony, how many years has it been since you grafted the soursop onto the cherimoya rootstock?
It looks very healthy.

[Tony714]

It's about 1 1/2 graft on 2-3 yrs rootstock.

Pretty sure he already gave his answer. We are waiting for you to report back with results.
