Grass is a block that was introduced very early in the game. It uses 3 textures: a grey one for the top which is then tinted to the correct colour according to what biome the block is in, one borrowed from the dirt block for the bottom, and an edited dirt texture with grass on the top edge on all of the sides. When covered by snow the side texture is white. On natural maps, grass appears on topmost blocks of dirt with no fluids or opaque solid blocks above them.
In mining, grass behaves just like dirt as it drops dirt resources and is best dug with a shovel; however, it makes a different sound when harvested and takes slightly longer to dig up. This can be used to tell when the player is about to break the surface when tunneling upwards.
Requirements
Grass grows spontaneously only during map generation. Afterward, it must spread from a nearby block. A dirt block must be placed with no opaque solid block or fluid on top of it and have a light level of at least 4 immediately above it to accept grass. There must also be a light level of at least 9 immediately above the source grass block. Grass can spread to any of the immediately adjacent blocks in the same layer, including diagonally. Grass can also spread to blocks one level above or three levels below the source block, even if the grass/dirt blocks are hovering in the air with nothing else directly touching them. It travels downwards much faster than it does upwards, and the more grass blocks that are in range of a given dirt block, the faster it will spread there. For example, it is possible for grass to directly "jump" to a dirt block three blocks below and one block to the side of the source. It can also spread directly downwards, so long as the target dirt block has no solid block directly on top of it (stone, for example, as opposed to torches).
Grown grass will soon revert back to dirt if an opaque solid block or fluid is directly above it, although transparent solid blocks (like Fences or Glass) will not kill grass when placed on it. As of Beta 1.6, grass will now spread to a dirt block with a transparent solid block above it.
Depriving grown grass of all light without setting another opaque solid block directly above it will not kill it. Tilling grass with a hoe will remove the grass and convert it to a Farmland block, which can then revert to a dirt block from excessive foot traffic or time left unplanted, which can then return to grass. Before the 1.6 update tilling grass would also drop seeds; however in the 1.6 update seeds can only be obtained from breaking Tall Grass.
Uses
- Passive mobs spawn only on grass blocks, with light level 9 or brighter in the space directly above. One can create a farm that will spawn animals using grass, or exclude passive mobs from an area by ensuring there is no grass.
- Passive mobs tend to wander towards grass blocks. They also wander towards light, but they ignore light over grass blocks and prefer them to any light levels below 10.
- Grass and Bone Meal will grow Tall Grass and Flowers.
- Grass can be used to make lawns, gardens or as a shade of green in Pixel Art that is on the ground.
History
Grass was one of the first two blocks in Minecraft, together with Cobblestone. When first introduced, Grass had it's top side texture on all sides. Later on, the side textures showed a signature 'tuft' of Grass overlaying Dirt. When Biomes were added in the Halloween Update the color of the top of the Grass corresponded to whatever Biome it was in. Attempting to place grass blocks by means of hacking one's inventory in Classic Creative Multiplayer will cause the server to automatically kick the player. Due to Creative mode's lack of dynamic lighting, grass that is in shadow will eventually die and change to dirt. Grass in one's inventory used to have a green colour on all sides of the block. Before the Beta 1.6 update, seeds could be harvested from grass with a hoe. Seeds can now be harvested by destroying tall grass.

Grass in inventory
- Grass and dirt changing between each other is a very common cause of chunk updates.
- Grass is one of the first seen blocks made in Minecraft, seen here. It had the top most face on all sides, resulting in "grass cubes".
- A grass block has become the favicon for Minecraft.net and the icon for Minecraft.exe and Minecraft.app.
- In Indev, placeable grass blocks were stored in chests for a short time, and when placed, no matter where, the grass would never die. The only way to kill the grass was to mine the block.
- In Survival Test mode, sheep would eat grass to regrow wool on their bodies, reverting it to dirt. Often, the grass would regrow just as quickly as sheep would eat it.
- Grass has a different texture when obtained in the inventory using an Inventory Editor or the /give command but will look normal when placed. The strange inventory texture appears to have the side face on all sides, or at least all sides that are visible.
- Grass will not disappear if a glass block or half block is placed on top of it.
- Despite common misconception, grass will grow onto a block with a torch placed upon it.
- As of Beta 1.5, the grass textures on the top of the sides are the same hue as the grass on top on Fancy mode.
The grass textures on the top and sides are the same as of Beta 1.5
- Tall Grass will spawn on grass blocks in certain biomes.
- Before 1.6, you could harvest seeds from grass. After 1.6, seeds can only be harvested from tall grass. 1.6 changelog
- As of Beta 1.6.6 Tall Grass can be grown on grass by using Bone Meal on a Grass Block. 1.6.6 changelog
