Grass Block

"Grass is probably Minecraft's most iconic block (suck it, Mycelium!) Along with cobblestone, it was one of the first two blocks in the game. Originally the grassy top texture was used on all sides, but it wasn't long until the block was given a side texture too, showing the dirt below. Grass blocks have changed a surprising amount throughout Minecraft's history, and today they're one of the most feature-packed blocks around."

Grass block is natural block that generates abundantly across the surface of the Overworld.

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

Post-generation
Grass grows spontaneously only during map generation. Afterward, it can spread only to a nearby dirt block. 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: Light-reducing blocks include any opaque block, as well as lava, water, ice, and partially transparent blocks like stairs and single slabs. 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.
 * 1) The dirt block receiving grass must be within a 3×3×5 range of the source block where the source block is in the center of the second topmost layer of that range.
 * 2) The source block must have a light level of 9 or brighter directly above it.
 * 3) The dirt block must have a light level of at least 4 above it.
 * 4) Any block above the dirt block must not reduce light by 2 levels or more.
 * 5) It cannot spread to coarse dirt.

Obtaining
A grass block can be obtained by mining it using a tool enchanted with Silk Touch. Otherwise, it drops dirt.

Endermen
Endermen can pick up grass blocks, and drop the blocks they are holding if killed.

Death
Grass dies and changes to dirt after a random time if directly covered by any opaque block. Transparent blocks can kill grass in a similar manner, but only 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 lit up.

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

Grass blocks also change to dirt when sheep eat them.

Grass dies when turned into a grass path.

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. Grass and leaves similarly change color with the biome.

These biome-specific colors also appear on maps.

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

Usage
Using bone meal on grass blocks causes tall grass 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 shorn sheep regrows its wool.

Grass 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 grass path block created.

Spawning
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.

Composting
Grass blocks can be used to fill up composters.

Trivia

 * Grass block, along with cobblestone, were the first two blocks added to Minecraft.
 * Grass blocks and dirt blocks changing between each other is a very 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 Bedrock Edition app.
 * In MINECON's goodie-bags, grass, along with the creeper, diamond, and the player, were given as foldable decorations.
