Minecraft wiki entry for Nether_survival, associated text: Vegetation farming is essential to tree farms, hoglin farms, and strider farms. When you bone meal nylium of any type, it generates vegetation on that nylium block and surrounding nylium blocks. The vegetation includes fungi of both types, roots of both types, and nether sprouts. Certain types of nylium generate more of their color type of vegetation, for example crimson nylium generates mostly crimson fungi and roots, but can generate warped vegetation. The only thing you need to obtain from these farms is warped and nylium fungus, used for breeding animals and growing trees. All other items are used only as decoration. There is no setup for this, but make sure you are doing it on the maximum amount of nylium possible so that there is space for it to generate. If your area of nylium is not wide enough, you can spread it by putting bone meal on netherrack adjacent to nylium. You can also obtain nylium in the Warped Forest, where endermen are often found holding it
