Back in the spring of 2015 I started with 150 cherimoya seedlings in 1 gallon bags. Ninety one plants survived their first summer. About half were up-potted to 5 G pots to go into their first winter. The remaining plants were left in 1 gallon bags.
A couple dozens survivors were planted in ground (by the building wall) in the following spring (2016). More trees died in the following years. Now there are only one strong vigorous tree that bloomed and fruited in 2021. The tree experienced the range of temperatures between 23F - 114F. It grows by the Southern wall and does have some protection from the building.
The first fruit was produced in fall of 2021 without hand pollination. There is another small fruit developing on the tree. The ripe fruit was very pleasant in flavor and sweet, medium in size. I collected all seeds and started germinating them.I plan to start propagating this tree in spring of 2022.
