So far I have not had issues feeding my villagers. I have 1 beet farm that I have maxed out the plots and workers. So far I only have 26 villagers total but my production is +34. Everyone has a tent at the moment but researching houses. I am used to games like Banished on Hard mode where if you don't get food locked down in the first 10 minutes everyone is dead so I may just have that going for me! 😄
One thing to note is make sure you have enough air wells and a water tank so they have water to plant the crops. Without that production can grind to a halt.
