Coarse Dirt

"Dirt has a ruder, less friendly cousin called "coarse dirt" that won't grow grass under any circumstances. You can make it by combining dirt with gravel in a 2x2 crafting grid, or hunt some down in the Mega Taiga, Mesa Plateau or Savanna Plateau biomes."

- Duncan Geere

Coarse dirt is a variation of dirt on which grass blocks cannot spread.

Natural generation
Coarse dirt can be found as large patches in all Giant Tree Taiga variants, Wooded Badlands Plateau, Modified Wooded Badlands Plateau, Shattered Savanna and Shattered Savanna Plateau biomes.

Usage
Coarse dirt has the ability to grow saplings, sugar canes, mushrooms, bamboo, and sweet berries which can be planted directly under appropriate conditions.

Neither mycelium nor grass can spread onto coarse dirt.

Coarse dirt can be tilled to become dirt and tilled again to become farmland.
