I do next to no farming. By middle of the first month I had sprinklers and a modest plot. By mid-summer, I had better sprinklers and a big plot. takes like 30 seconds each day to run through the field and pick up any crops. another 30 seconds to re-seed if necessary. watering cans are for chumps. I've got like an 80x80 field now. I spend most of my time in the mines/
and/or fishing. I'm on spring 3 of my second year and have 200k gold and make 5-6k every day just from all my crab pots. I can make 5-10k a day in the mines or roughly the same from fishing.
but yeah, except for the first day of each season which I have to spend tilling/seeding, I do almost nothing to my farm except let it make money for me.
