Crop farming allows players to plant any of several crop plants on farmland, which then grow over time and can be harvested for food. This page covers four separate crops, all of which share essentially the best minecraft vanilla servers growth mechanics, though they produce different crops. All four seeds need to grow to maturity to produce more crops.
Each crop requires an initial «seed stock» for planting, and getting those first few items can be non-trivial. After the first few seeds, or the first carrot or potato, are planted, they will eventually produce more seeds or vegetables than you started with. Carrots and potatoes are usually not found until somewhat later in the game. Wheat is grown from seeds, which can be collected by destroying tall grass. Harvesting a mature wheat plant yields 1 piece of wheat and 0-3 seeds. In contrast, carrots and potatoes are their own seed, and the plants are not found in the wild.
