Minecraft wiki entry for Nether_survival, associated text: You'll want wood for tools and torches (and perhaps to smelt into charcoal), so make a tree farm as well. Wood also provide charcoal for torches and smelting. Oak trees also provide the occasional apple for golding, but that's not really a food supply. If you want Nether woods variants, you can grow Huge fungus as they don't need dirt, but nylium to grow. Also Nether wood is inflammable.
