Figs are one of the most common plants in Greece. I've seen them growing wild at almost any place. Sometimes i even saw realy huge fig trees, like 10-12 meter broad crowns growing at the most unfavorable and dry places, like rocky sandy slopes at ancient ruins.
I do have a small tree myself in Greece (i live abroad though) in the garden. Don't ask me plz what sort it is, someone of my relatives whose house is in the same garden planted me that tree a few years ago along with a pomegrenade. I also heard from two friends of my parents who live in Austria that figs are also able to grow outdoors there, as long as they are somehow protected, like next to a wall or in a corner. The fig tree in their garden in Austria, not a particularly huge nor very productive one (i think its record were 3 figs in a year) :blush:has survived there many winters so far and last year's winter was exceptionally cold and frosty for a very long time.
For my tree in Greece, i only occasionally water it during summer, and so far i never gave it any fertilizer, not even dung. I do suppose that they are a bit like cacti, best with little care on their own and with few additives. I also never saw a pest on my tree so far. I must warn you though, fig trees have a nasty sap that can cause blisters, irritation and itching of the skin.
