its actually a pretty drought tollerant species.
a close relative lives in Africa and has been known to survive and fruit
with very little water.
That said, i have heard they like more water when fruiting.
i had a large one i lost 2 years ago
it was abotu 10ft, in the ground only 2 to 3 years, but very healthy looking.
it put out lots of nice fruit, then one day it turned up its toes.
the only thing i can think of, is either i had planted it too deep
(i had noticed ,mulch had crept up around the soil line a good inch)
or
the fact that it had rained for at least a week straight
and we had a little standing water for a few hours on and off.
and it was in a bit of a low spot.
or, a combination .
after i pulled it up (6 month later)
the roots did not appear rotted, so i have no idea what killed it.
lat month we had a tropical storm come through New Orleans
its been raining every day for a month
ive been watching my 5 Juju closely.
They actually have been putting out new growth.
fingers crossed.
i have heard they will abort fruit when they are young at times.
a couple of mine flowered profusely in spring, but ive only 3 fruits to show for it.
i am getting a few flowers with this new growth, so i am hoping i can get a few fruit.
they seem to like good drainage. the last one i planted, i had raised the area with a few bags of soil
its a good 3 inches above grade... i added some mulch around the base
it seems very happy now... i like the tree, i love the fruit.
good luck
