Wheat
Wheat is the first crop you grow. Herm sells Wheat seed from the start; plant 4 seeds in a Garden Bed from Gardening (5 green), and the bed grows the wheat by itself. When you harvest you get the Wheat back along with new seeds and 2 Leaves.
Herm asks for 5 Wheat in Planted and Delivered, and the Wheat he sells himself only appears after that quest, when his store reaches its second tier. So the 5 for the quest have to be grown.
Planting needs Farming mastery, at least 1, which the rusty shovel on your hotbar gives. Planting is scored with stars like cooking, and its full requirement is Farming 2.
A bed grows in about 16 minutes, a little over two in-game days. Growing has 12 steps, but the 4 planting steps count toward them, so 8 are left, at 2 minutes each.
Garden Upgrade I more than halves that. It shortens each step to 105 seconds and raises the garden’s growing skill to 4, twice what wheat needs, so every tick moves a wheat bed two steps: 4 ticks, about 7 minutes.
At the Millstone, 4 Wheat make 5 Flour, and 4 Wheat seeds make 2 Seed oil for Melted Fat.
