By day 25, I am swimming in food from my crops and by day 40ish I go almost a week before even remembering to touch it.
Instead of only maybe 15 farm plots in A19, I now do on average of 60 farm plots. I plant around 15 potatoes, 25 corn, 10 blue berries, 12 shrooms, and 5 pumpkins.
I rotate on which item I'm running low on and plant more of those. I average getting 6 out of 10 seeds per crop harvested and then replant back up to what my needs are.
I also supplement food that I find on traders and vending machines, as I'm swimming in dukes.
