Gentle Harvest Mod is a small mod that attracts players keen on farming. In this mod, crops will be automatically replanted as you harvest them (by right-clicking them). In vanilla Minecraft, these crops are wheat, potatoes, carrots and cocoa pods. Besides, you should remember that only fully grown crops are affected. It should also be compatible with any mod-added crops that extend BlockCrops or BlockCocoa.
