Just like the other harvesting achievement, except this one require you to grow and harvest 1 of each of either: carrots, corn, lettuce, tomato, potato, wheat or onions. Those last two are semi-rare and will take some time to find 3 of each in order to plant 1 seed. You thankfully get enough when harvesting to cover the cost plus bonus extras.

To find the farming areas, zoom out the map fully and head to grid L38 and/or O34 to find two farms that are suitable for growing what you need.
