Why would you need to hire someone? If it’s a farm meant to provide food for people then it’s commonly owned and the people who work there are state employees, the purpose of the farm being to make food, not profits.

If it’s something you do because you want to and out of passion, then why would you hire anyone? Sure, you might want some help, but then you just get people who are passionate about it as well, and you share the produce. Like a community garden.
