Seagrass is a non-solid plant block that generates in all oceans, except frozen oceans.

Obtaining[edit]

Seagrass can be destroyed instantly with any tool, item or the player’s fist, but it can be only obtained using shears, or it will drop nothing. Regular seagrass drops 1 seagrass when harvested with shears and tall seagrass drops 2 seagrass when harvested with shears.

Turtles[edit]

Turtles will drop 0–2 seagrass when killed. The Looting enchantment will increase the maximum number of possible seagrass drops by 1 per level.

Natural generation[edit]

Seagrass generates in either its tall or small form in ocean biomes near kelp, and will also generate in rivers, underwater caves and swamps by itself, replacing ice^[1] and planks^[2] as necessary.

Bone meal[edit]

Using bone meal underwater will generate seagrass. The bone meal must be used on a non-transparent block under at least 2 blocks of water, with the water directly above the block being non-flowing. If these conditions are met, a one-block tall seagrass will generate on that block, and if available, seagrass will also generate on surrounding blocks.

Usage[edit]

The seagrass item can only be placed on non-transparent blocks.

Like grass, snow layers and other such blocks, placing blocks inside seagrass will delete it. However, it will block coral fan placement.^{[Bedrock Edition only]}^[3]

Breeding[edit]

Seagrass can be used to breed turtles.

Bone meal[edit]

Applying bone meal to a one-block-tall seagrass will turn it into a two-block-tall seagrass, assuming there is enough space. It can also be used to completely waste bone meal if no such space exists.^[4].

History[edit]

Java Edition Classic
May 21, 2009			Notch shows interest in adding a "seaweed" block.
Java Edition
1.13		18w07a	Added "sea grass".
		18w07b	Sea grass is now used to breed turtles.
		18w07b	The block that sea grass occupies will now behave more like water. For example, mobs can now no longer spawn within the plant underwater, nor can they replenish their breath by swimming through it.
		18w08a	Sea grass will now no longer have an animated texture as an inventory item.
		18w14a	Sea grass can now generate in rivers and swamps.
		18w19a	Sea grass will now generate in underwater caves.
		18w19a	"Sea Grass" has now been renamed to "Seagrass".
		pre2	Seagrass can now be destroyed by sponges.^[5]
		pre6	Conduits and kelp can now replace seagrass.^[6]
		pre6	Added 5 new sound events that apply to seagrass: `block.wet_grass.break`, `block.wet_grass.fall`, `block.wet_grass.hit`, `block.wet_grass.place`, and `block.wet_grass.step`.
Bedrock Edition
1.4		beta 1.2.14.2	Added sea grass. It has the same texture as regular grass, rather than the texture of seagrass in the Java Edition.
1.4		beta 1.2.20.1	The sea grass texture has now been changed to the Java Edition's texture.
Legacy Console Edition
TU69	1.76	Patch 38	Added sea grass.
