I have two of the Giant cherimoya and I dug up the one that was in the ground.
It was pushing 6' and it seemed miserable in Florida. They have some new growth in the
Winter but in the humid Summers they are definitely not happy. I was figuring they
would never flower here? Last Spring I trimmed it to try to induce flowering and nothing.
Both of mine are in 15 gallon pots and starting to put out new leaves when all the other
annonas are shutting down.
