Kelp is an underwater plant that generates in most oceans.
Kelp can be bought from wandering traders for 3 emeralds.
Kelp can be placed underwater by hand, or anywhere by the use of commands such as
/setblock. Placing it by hand gives it a random
age value between 0 and 24. Kelp can be placed only in water source blocks or downward-flowing water, not horizontally flowing water.
When placed in downward-flowing water, the flowing water transforms into a water source block, which can be useful for faster bubble column elevator creation.
Any building block can be placed on top of a kelp plant, which is useful for building structures over a deep ocean without needing to build from the ocean floor.
Blocks of dried kelp can be used as fuel for furnaces.

Placing kelp into a composter has a 30% chance of raising the compost level by 1.
Kelp can be planted on a broad variety of blocks. It grows underwater if it has either a source block of water or flowing water above it. If flowing water is above it, the kelp plant transforms the flowing water into a water source block when the plant grows into it. Neither players nor dispensers can remove the water source block a kelp grows in without breaking the kelp first.
Kelp, when planted, is generated with a randomly chosen age value, which can be checked when pressing F3[Java Edition only]. The age value of a newly planted kelp plant varies randomly from 0 to 24. Each time the kelp grows in height by one block, the newly generated top of the kelp plant increases its age by 1. When the top block of the kelp plant reaches an age of 25, it stops growing. This means that kelp can naturally grow to a height between 2 (if the first kelp plant had an age of 24) and 26 blocks (if the first kelp plant had an age of 0).
When a kelp plant block is broken, the age of the kelp plant block underneath is randomized to a value from 0 to 24 and the kelp continues growing until it reaches age 25. It is possible to use this mechanic to cultivate a kelp plant to increase its growth height beyond its natural maximum height of 26 blocks. This can be done by breaking the top-most block of the kelp plant each time it reaches age 25. A kelp plant cultivated by a player in this way repeatedly grows until it reaches the water surface.
Each time it receives a random tick, kelp has a 14% chance of growing.
Kelp farming is similar to farming sugar cane, although kelp must be placed underwater. Automation of harvest is easier because items float up in water.

|age||A freshly-planted kelp starts with a random age between 0 and 24.|
Below age 25, a kelp may try go grow more kelp above it with the same age value incremented by one.
Kelp stops growing at age 25.
|Name||Default value||Allowed values||Description|
|age||The age of the kelp. The kelp renders as a non-top piece if there's another kelp above it.|
