Wheat is an item obtained through farming and crafting. Seeds for growing wheat can be obtained by breaking tall grass, with a 30% chance success rate, or can be found in chests in dungeons (one to four wheat found at a time).
Creating a wheat field around the player's shelter can be highly beneficial, as it provides a steady source of food (bread, cake, etc), and is essential for breeding certain animals (sheep and cows), should the player decide to build a farm containing pototoes and carrots as well. When you click on two animals near each other with wheat, hearts will appear, sometimes called Love Mode, and it will make a baby.
Before planting wheat, the user must till the ground with a hoe. Wheat grows most efficiently when planted on a damp tilled dirt block, the 'damp' state is achieved by having a water source within four blocks of the tilled dirt block, or rain. When harvesting wheat, the player will collect one to two wheat and zero to three seeds, which can be replanted to grow more wheat. If you use the 'pick block' option on a full grown crop, it will give you the 'crops' item. This item is not found in the creative inventory, it is instead used like seeds so it will grow.
