Below is a walkthrough for the Harvest 6 Kinds of Vegetables task in Rune Factory 5.
Client: Fuuka
Objective: Harvest 6 different vegetables
Reward(s): New Shop Inventory (Sword Flower and Shield Flower Seeds)
After accepting the task from the Task Board, Fuuka will ask you to harvest 6 different kinds of vegetables at your farm. Any unique vegetables you’ve harvested up to the point will be counted as part of the task. Depending on what tasks you have completed, you can potentially buy turnip, potato, spinach, radish, yam, fodder and carrot seeds from the general store. Pick up enough different ones to satisfy the objective then plant them at your farm. Harvest them when they are ready and turn the task in at the Task Board.
