Plant a Green Cabbage in Sunsong Ranch. You can purchase seeds from Merchant Greenfield in the Halfhill Market.
Grandpa always said that the bellweather of a true farmer lies in the quality of his cabbage. Any time a new farmer came into town, he'd buy a few heads of cabbage to see what they knew.
Now, I'm the new farmer, and this is my big chance to prove myself. Could you plant some cabbage for me?
