Grass Block

A grass block is a natural block that generates abundantly across the surface of the Overworld.

Obtaining
A grass block can be obtained by mining it using a tool enchanted with Silk Touch. Otherwise, it drops dirt. It can also be obtained by killing an enderman that is holding a grass block.

Natural generation
Grass blocks generate naturally in most biomes in the Overworld and as part of villages.

Spread
Grass can spread to nearby dirt blocks, but not coarse dirt. Grass spreading without player intervention depends heavily on the time of day. For a dirt block to accept grass from a nearby grass block, the following requirements must be met: When Grass is Random ticked, it spreads by checking 4 blocks within range and converts any dirt blocks selected into grass.
 * 1) The dirt block receiving grass must be within a 3×3×5 range of the source grass block where the source block is in the center of the second topmost layer of that range.
 * 2) The source grass block must have a light level of 9 or brighter directly above it.
 * 3) The block directly above the dirt block must allow light to pass through it and hit the dirt block, even though the actual light level does not matter. That means blocks that partially let light through such as stairs and slabs must not have their light-blocking side(s) facing the dirt block.
 * 4) The block directly above the dirt block must not be lava, water, or a waterlogged variant of a block.

Though water and lava are both light-filtering blocks (meaning they decrease skylight by 1 level but do not affect block light), other light-filtering blocks such as ice and slime blocks do not block grass from spreading to the dirt block. Grass blocks can grow under all other transparent blocks like glass, fences, or torches. Grass jumps directly from one block to a neighbor and is not affected by gaps or other blocks being "in the way." Grass blocks spread at random intervals and have an equal chance of spreading to any suitable dirt blocks that are in range. Because grass can spread as much as 3 levels downward, it tends to spread down slopes much faster than it spreads up them.

Mob loot
Endermen can pick up grass blocks, and drop the blocks they are holding if killed, making it the only way to obtain grass blocks without the use of Silk Touch.

Appearance


The coloration of grass blocks is dependent on the biome they are in. A grass block always uses the color set to its location, regardless of how it was placed or of its source. This affects the side and top of the block. Grass and leaves similarly change color with the biome.

These biome-specific colors also appear on maps.

List of colors
These values are generated by the biome dyeing algorithm. See Biome colors for more information.

Usage
Using bone meal on grass blocks causes grass, tall grass, ferns, large ferns, and flowers to grow.

Passive mobs tend to wander toward grass blocks. They also wander toward light.

When a sheep eats a grass block, the block becomes dirt, and a sheared sheep regrows its wool.

Tilling a grass block with a hoe converts it to a farmland block.

Dirt paths can be created by any type of shovel on the side or top of a grass block with air above it. The shovel loses 1 durability for each dirt path block created.

Death
Grass dies and changes to dirt a random time (when a random tick lands on the block) after it has been covered by any opaque blocks. Transparent blocks can kill grass in a similar manner if they cause the light level above the grass block to be four or below (like water does), and the surrounding area is not otherwise sufficiently illuminated.

Spawning
In Java Edition, animals occasionally spawn on grass blocks that have light level 9 or brighter in the space directly above. This is quite rare and requires that there be few other animals nearby or in the spawn chunks. Most animals are instead created along with the terrain.

In Bedrock Edition, most animals require surface grass blocks (grass blocks with no solid block anywhere above them at the same x, z coordinate) to spawn. Animals regularly spawn in most overworld biomes on surface grass blocks that have light level 7 or brighter in the space directly above.

Turning into a snowy grass block
Grass blocks instantly turn into a snowy grass block if a layer of snow or a snow block is placed on top of the block. Removing the snow layer instantly turn the block into a normal grass block. You can also use a debug stick (/give @p minecraft:debug_stick) to turn it snowy with no snow.

Composting
Placing grass blocks into a composter has a 30% chance of raising the compost level by 1.

Trivia

 * Grass blocks and dirt blocks changing between each other is a common cause of chunk updates.
 * A grass block has become the favicon for minecraft.net, and is the icon for the Minecraft launcher and the app.
 * In MINECON's goodie-bags, grass, along with the creeper, diamond, and the player, were given as foldable decorations.
