Just my two cents from someone growing in a colder climate. Sugar apples, cherimoyas, and atemoyas are definitely doable but you need to have your processes and setups dialed in. Ultimately you'd be wasting your time if you don't have a decent amount of space to provide them and a heated greenhouse, or possibly a really sunny southern facing bay window or sunroom. As for a lot of these newer annonas and duguetias, you have to look at them as almost a novelty. I think there's been only one person to fruit a duguetia in mainland US and that's in southern Florida. Thats the way I look at it, I don't have high expectations for fruit but if I can get the plant to thrive that's cool, if it flowers even better.
100% agree
Need to use right rootstock and rootmakers to prevent root rot🥲
Now duguetia definitively needs more trials and different sp. But in general it’ll take a while and very though and who cares anyways?
The one that fruited in the USA tasted like blue cheese ( of course not a fair sample since it was first fruit, but it gives you a general idea)
Hopefully some better ones we can fruit instead.
