As a real head of a settlement, you need to be able to do all the work, especially when it comes to planting crops. Let us remind you how to do it!
In order to plant some crops, first you need to buy some garden beds from Household tab, "Plants" section.
After that, you will be able to plant onions or any other crops you want by clicking on your garden beds on your land.
With love,
Your Farland Team
