Grass is a type of block which covers most of the above-ground landscape. It enables many different plants to grow on it.

Natural grass types

These types of grass occur naturally throughout the world. They can also be planted manually with their respective seeds. Regular grass can furthermore be planted with the Staff of Regrowth or Axe of Regrowth(Desktop, Console and Mobile versions).

If there is room below a grass block, the respective type of vine can grow downward from it. Acorns planted in grass (except Mushroom grass) will grow into the respective type of tree.

Wild plants on grass

These weeds and flowers grow naturally on the different types of grass on the surface. They do not grow below the surface (except on Jungle, Mushroom, and Ash grass), and do not grow on mowed grass. Plants growing on painted grass blocks will take on the block's color.

Some of these plants can be planted manually with Flower Seeds(Desktop, Console and Mobile versions), Flower Boots(Desktop, Console and Mobile versions), and the Rubblemaker(Desktop, Console and Mobile versions). The rest cannot be planted manually.

Hallowed grassHallowed grass
  • Contributes to the Hallowed biome tile count.
  • Drops 1–2 (tile ID 110) / 2–4 (tile ID 113) Hay if cut with a Sickle.
  • Only grows when there are proper walls or no walls at all.

Walls eligible for plant growth

When trying to grow some types of plants, the tile of the soil block and the tile above the soil block must not occupied by walls, or occupied by one of the walls listed below.[1]


This section is about grass spreading onto bare soils. For details about grass types converting other grass types, see Biome spread § Grass.

Grass of any type spreads from existing blocks to other blocks of the correct soil type. The following restrictions apply:

  • Pure, mowed, and mowed Hallowed grass does not spread below the surface whatsoever.[2] The player needs to be at least at 4 feet (on the Depth Meter) on the surface for these types of grass underneath to be able to spread.
  • Grass only spreads to an adjacent block, i.e., a block within the eight tiles directly surrounding the grass block.
  • Grass does not spread to blocks that have lava in one of their adjacent tiles.
  • Grass only spreads to blocks that have at least one tile of open space within their adjacent tiles (i.e., grass does not spread to blocks that are fully surrounded by eight solid blocks).


  • Dirt Blocks and Mud Blocks are both eligible soils for both types of the evil grasses. For instance, Corrupt Jungle grass can spread onto Dirt Blocks (resulting in regular Corrupt grass), and regular Corrupt grass can spread onto Mud Blocks (resulting in Corrupt Jungle grass).
  • The mowed grasses also spread to adjacent Dirt Blocks (only above the surface), but the resulting new grass will not be mowed.
  • Painted grass will spread its paint, too.
  • Corruption and Crimson thorny bushes can create Corrupt/Crimson grass on adjacent Dirt Blocks (Desktop, Console and Mobile versions) and Corrupt/Crimson Jungle grass on adjacent Mud Blocks.


  • When mining blocks with grass, the grass will absorb the first hit from the pickaxe/drill. Hence, unlike mining most blocks, a tool with high mining speed will actually always outperform a slower tool, even if the slower one has higher pickaxe power. This means that the best pre-Hardmode item for digging grass would be the Bone Pickaxe. In theory, the Shroomite Digging Claw(Desktop, Console, Old-gen console and Mobile versions) has the best speed out of the Hardmode tools.
    • This becomes particularly important in the Jungle biome, due to the prevalence of Jungle grass.


Examples of the two unused grass graphics.
  • There are unused graphics for two other grass types in the game's files. One is a yellow-green grass akin to Jungle grass, although it is tiled on dirt. Its internal name Tiles_2_Beach.png implies that it was originally intended for the Ocean. The second is a variation of Flesh Blocks, tiled to work as a grass.
    • Crimson grass is referred to as FleshGrass internally, so the second grass variation may have been an early Crimson grass sprite.



  • Desktop 1.4.4:
    • Added Ash grass.
    • Corrupt grass and Crimson grass can now grow and spread on mud.
    • Mushroom grass can now glow different colors when painted.
  • Desktop
    • Artificial Jungle biomes now require 140 Jungle grass blocks instead of 100.
    • Added mowed grass.
    • Wild plants on Jungle grass and Glowing Mushrooms no longer grow on actuated blocks (which used to result in their items immediately breaking off and falling to be collected).
  • Desktop 1.2.4:
    • Replaced grass graphics for when they are surrounded.
    • Grass is now removed when a player covers it in solid tiles.
  • Desktop 1.2.3:
    • Acorns can now be planted on all grass types.
    • Corrupt grass, Crimson grass, and Hallowed grass wall spreads further.
    • Fixed bug where the player can not pick up Crimson grass and Hallowed grass with Dirt Rod.
