Sugar Cane

Sugar cane (Formerly reeds, also known as bamboo or papyrus) was added in the v1.0.11 patch. It can be found randomly on grass, sand, or dirt blocks that are near water and grows to a maximum height of four blocks as of Beta 1.4, and additional layers may be added manually by the player, or spawned during map generation. More sugar cane may be placed on top of them, and they will also support other blocks. There appears to be no pattern to the spawn algorithm. Sugar cane may occasionally grow in tundra Biomes, but is extremely hard to find because Ice replaces nearly all water next to land. Sugar cane can also be found naturally underground, although this is very rare because it requires dirt blocks next to a subterranean lake.

Like cacti, removing the bottom section causes all sections above it to be removed as well, allowing for quick harvesting; one can also "shave" off the upper sections and leave the bottom section planted for saving time. It can be crafted into paper and sugar. Bone Meal doesn't work on sugar canes and won't speed their growth.

Farming
Farming sugar cane is similar to farming crops. Like the real plant, sugar cane must be planted on a grass/dirt block immediately adjacent to water. It cannot be placed on blocks diagonally adjacent to the water, or on a different level. If it can be placed on a tile, it will grow there. Unlike wheat, it does not require a tilled field to grow. Sugar cane, like saplings, wheat, and cacti, will only grow if the chunk they are on is loaded into memory.



If the water source is removed, the sugar cane will not break instantly. When the sugar cane tries to grow, the game will realize it has no adjacent water, and the sugar cane will disintegrate, leaving two sugar cane items instead of one. This is not as efficient as growing sugar cane normally, because you must replace the water supply to re-plant the sugar cane.

Sugar cane is impervious to water and lava. It can block water/lava flows, and when water/lava hits it from above, the water/lava is spread out as by a normal block. Neither the sugar cane nor the block they stand on can be lit on fire with the Flint and Steel, although attempting this still lowers the durability of the Flint and Steel, in a manner similar to glass.

The water/lava blocking ability of sugar canes includes being placed in the middle of an existing flow (they still need to be adjacent to water).

Sugar cane used to block projectiles as any ordinary block, which means projectiles shot at anything inside or past the sugar canes would be blocked. However, if you stood in a patch of sugar canes and fire arrows/throw snowballs, those projectiles would ignore the sugar canes where your head was located. A Ghast's fireball will not pass through sugar cane, but will collide with the sugar cane as if it is a normal block. As of update 1.6, sugar canes and projectiles interact differently, and arrows are no longer blocked by the sugar canes.

When planted underwater, sugar cane, like Slabs, displaces the water, leaving an air pocket. If a sugar cane block is placed next to or on top of another sugar cane block, they will both be instantly destroyed if underwater. This will still drop the two sugar cane blocks that were destroyed as resources.

Trivia

 * You can plant sugar cane on a tile covered in snow even if there is no water adjacent to it. It will break when it grows.
 * When sugar cane gets activated by a redstone wire the sugar cane breaks. See Sugarcane Farming.
 * In Beta 1.6, the max height that sugar cane could grow to was increased to 4.
 * Before Beta 1.2, sugar cane was officially called "Reeds." The name change was a result of Notch needing a way to craft sugar to make Cakes.
 * Ghasts cannot see through sugar cane, which would make it a safe block to make walls out of despite its transparent nature. Unfortunately, sugar cane cannot normally be planted in the Nether due to the lack of water.
 * It has been verified that sugar cane grows more rapidly in areas with a great amount of lighting than in areas with less lighting.
 * When farming, it is recommended to hit the second block instead of the bottom to avoid the need to replant.
 * Sugar cane can be placed on the side of an ice block.
 * In previous versions of Minecraft, Automatic Reed Farms could be made, as Reeds could be washed away with water currents or instantly destroyed by removing the water adjacent to them. Since the change to sugar cane, neither of these techniques work. However, removing the water adjacent to a fully grown sugar cane and then breaking it manually will break all adjacent sugar canes (provided the water adjacent to them is also removed).
 * Sugar cane can be used underwater to provide air for extended periods of time. The technique involves rapidly placing two blocks of cane directly at your feet, creating a 1x1x2 pocket of air. If on flat surface, the cane will break after your air is replenished and return to your inventory. However, on a ledge it will stay in place providing a reusable air pocket. This also works on blocks other than Dirt.
 * Sugar cane can be planted away from the water if planted on a block currently on fire.
 * The sugar cane block is called "Sugar cane", but without a capital C at cane, unlike the item.
 * Sugar cane can be used to make underwater doors and walls. This relies on the unique ability of sugar cane to allow the player to pass through, but not allow water to flow through it. This can be used to make a Creeper proof house, provided the rooms underwater are well lit. It is advised to have these sugar cane walls be 2 blocks thick, so that if you accidentally break one sugar cane plant, it can be replanted without having to fight the flow of water rushing into your house.
