Tutorial:Fern farming
Fern farming is a process of multiplying ferns by applying bone meal to existing ferns and mining the increased layer with shears.
Why bother?
Ferns, like grass and flowers, are natural blocks that are well-suited for outdoor decoration. However, being limited to jungles and cold biomes, they may not be easily obtainable in large quantities without a farm. Ferns can also be composted.
Manual farming
Using bone meal on a fern causes it to grow into a large fern, which can then be mined with shears. The process can then be repeated.
AFK farming
The system can be automated with a dispenser with bone meal and a minecart with hopper system to pick up the ferns. A larger fern farm is possible, which requires a minecart system to move the player around. A hopper clock can be used to dispense shears after the previous set of shears is broken.
