the nocull parameter means that faces are rendered in the front and in the back. If your model is a ball, it´d be stupid to use nocull because the inside of the ball would be textured too, which is unnecesary. But for fences, trees and other things like canvas maybe, nocull allows you to save polygons by making each face using that material to render both sides. The downside of this is that the backface will be as bright as the front face. So if you, for example, create a canvas roof and use nocull on it, if the normal aims to the sky then when looking at it from the bottom it´d be lit too. It is better for your situation to make two paralell polygons aiming to opposite directions than to use one with nocull. What you should do now is first remove or comment (adding two // at the beginning of the parameter) the line that reads nocull, then go to your modelling program select all leaves polygons, duplicate them and then invert the normals of the new generated polygons.
