Using bone meal on netherrack that is placed next to or adjacent to warped or crimson nylium transforms the netherrack into nylium of that type. No block can be above the netherrack during this process. This transformation can also be done by activating a dispenser with bone meal directly into that netherrack block.
Similar to grass blocks and mycelium, nylium decays (immediately on a random tick) into netherrack when an opaque block is placed above it. However, unlike grass blocks and mycelium, it does not decay underneath water and lava.
Similar to grass blocks, the player can apply bone meal to nylium. This nylium, along with nearby nylium, generate vegetation that occurs in their native biome (crimson nylium generates crimson forest vegetation and warped nylium generates warped forest vegetation).
Nylium can be placed under note blocks to produce "bass drum" sound.
