Hi Paolo,
Sorry to play the black craw, but hoping for you that those trees are adapted to your zone.
Why the hell, did they have a figtree in a greenhouse the whole year long ? Did I miss something ?
Did you get information on when the fruit would ripen for them ? Black, green, yellow ?
Since the tree has been dug out, now is a good time to separate each trunk/root-shoot and turn it into a new tree.
