When I have one seed from farming, I want to get more seeds. How do I do that? I always seem to get one seed back when a farmer collects the full grown crop.
As your farmers increase in level, they will have better chances of getting more seeds. The total number of seeds you have increases slowly, but it does increase. Early in the game, you'll want to focus on Foraging for food. Farming is more of a late game food source.
