The stuff I've had the best luck with so far are sub-tropicals and tropicals from non equatorial areas, including:
pomegranates
figs
strawberry and lemon guava
natal plums
eugenias
citrus
fig and POM indoors ?
do you have a small star to produce light ?
most ive talked to in the fig forum
had told me any fig they grew in shade had very low production.
ive been under the impression POM was the same way also... is it not ?
one trick i do use for any plant that is in shade a lot
is extra iron and magnesium
they darken the leaves allowing it to photosynthesize with less light.
my Feijoa 's leaves got much darker, and the plant looked a lot healthier.
its also helped, mulberry, katuk, citrus, persimmon... and fig too.
