Hi Jimmychao,
I have some trees with 2 figs on one node . And that is already rare.
The problem still is that on those nodes, one fig will take it all, and the second barely really grows to be something edible.
My Sultane and my BT both did that, and on those nodes one of the figs fell to the ground after some time.
So for now, I haven't had twins figs both ripening.
Now to have 4 figs on one node, that is really unusual for ficus carica. Is that tree a ficus carica ? Can you show us the leaves ?
The internodal spacing looks weird to me .
By the way, just wondering : how far are you form the nearest nuclear plant :) ? Do they glow in the dark ?
