Melons are naturally generated in jungle biomes, villages, and woodland mansions. When you break a melon you will receive melon slices. Once eaten, melon slices will give you melon seeds that can be then planted in farmland blocks in order to grow new melons. You can make melons by filling up the 3x3 crafting grid with 9 melon slices.

Melons are also a reliable source of melon seeds that can be used to farm melons. You can also sell melons to villagers for emeralds in return.
