The crop plot is used to grow plants from seeds. It can hold and grow up to three plants. To plant a seed, place it in your hotbar, select it, and press the use key on the crop plot. The plants will grow until they are fully grown, at which point the player may harvest them.
Currently only raw potatoes can be planted in the crop plot.
The crop plot looks like an old wooden crate reinforced with rope. It is also filled with dirt, whose source is unknown.
