I've had more luck growing atemoyas than cherimoyas here.
If it's a cherimoya, I have it on an atemoya rootstock.
Dr. White, Booth and Honey Heart grow well for me here.
They're more resistant to rot with the amount of rain and overcast we get here.
IIamas don't grow well here, even on atemoya rootstock.
Rollinia, very cold hardy here for some reason.
Soursop, haven't had any luck unless they're grown from seed or on atemoya rootstock.
I have several sugar apples, they are very cold hardy for some reason.
Frost does damage their leaves, but they bounce back very well.
