duplicating textures to multiple objects

I have gone through and duplicated the same branch several times and aranged them on a single tree, my problem is that I forgot to add the texture to the original branch before duplicating and arranging them. Is there a way to apply the same texture to multiple objects in one go? I would really prefer to do this seeing as I spent about two hours getting the branches where I want them. I would hate to start over.

Thanks a lot for the help

If you’ve got your texture as part of a Material, just select all leaves and lastly one with the Material, press Ctrl+L and select Materials.
