> Nether Wart Blocks are decorative blocks from the 1.16 Nether Update. They generate as part of huge crimson fungi or can be crafted from 9 nether wart. They cannot be uncrafted back into nether wart. Use a hoe for fastest mining. Composting gives an 85% chance to level a composter, but is less efficient than composting individual warts. Importantly, piglins, zombified piglins, and hoglins do not spawn on these blocks, making them useful for safe flooring.

## Primary Uses for Nether Wart Blocks

### Decoration
Nether wart blocks are a vibrant red building material. They look great in crimson-themed builds, redstone contraptions, or as a striking accent.

### Not a Storage Block
Unlike other crop blocks (like hay bales or melon blocks), nether wart blocks cannot be uncrafted back into nether wart.
> Nether wart blocks are not a compacted block as they cannot be crafted back into Nether wart.

So don't rely on them for compact wart storage – you'll lose the 9 warts permanently.

### Composting
Nether wart blocks can be fed into a composter with an 85% chance of leveling up the pile.

However, note that using a single nether wart block is less efficient than composting 9 individual nether wart items.

### Mob Spawning Prevention
One of the most useful properties of nether wart blocks is that piglins, zombified piglins, and hoglins do not spawn on top of them.

This makes them excellent flooring material for buildable farms and safe zones in the Nether. Other mobs like skeletons and endermen are not prevented from spawning.
