I used Ginger Island for fairy honey. Grows all year without issue, and getting the coal to make the beehives isn't that bad, when you have a burglar ring, double chance of coal perk, and monster musk to get more monsters to hunt. I put down enough bee hives to get a tad over 200k every 4 days. I also grow a a lot of taro roots. It's kinda fun getting the bones to buy the taro roots, and then letting the river irrigate them. I mainly save those and cook them for that 100,000 qi cooking challenge. It's a simple meal to make and high value. I also have 10-20 crystalriums to make diamonds too.
For my main farm, I kept it to around 300 plots of land and grew a variety of crops on them. They are managed by two junimo huts. I also have a bigger area to grow high fiber and a giant pumpkin crop (my wife wants giant pumpkins, so she gets a giant pumpkin). I just keep 1-2 of each of the animals, just so they keep me supplied, especially for pumpkin soup. Took me a ton of time but I also got two auto-petters, so I don't have to even think about dealing with animals anymore, but I'm still trying to figure out the optimum amount of greenspace, so they don't eat all the grass when it's not winter. Green house has some ancient fruit, but it's not full or anything. I'm thinking of using the new super fertilizer to grow all iridium quality crops, since it doesn't seem to wear out.
I was never into doing things the most efficiently. I have a grove for tapped trees (just realized that I could have been tapping the new trees for sap, so I need to make room for that), and a bigger one I use to get wood. I have... I think it's 8 fish ponds that I used mainly just to grow stock, cause there is no need for me to have good quality fish for anything, and I like having a bunch of every item. I turned the bigger farm pond into a crab pot trap, and have some space for growing grass. I have a monster hut but never did anything with it. I have another 10-20 crystalariums that I grow mainly diamonds and amethysts for gifts. There's also a ton of lighting rods, because I really hated lighting destroying my stuff. Like, I'm kinda surprised that more space isn't used for lighting rods when I look at farm showcase videos. Like, I had 20 of the things and it still wasn't enough. I was really mad one time because after I got my first sweet gem berry growing lighting hit it, and I had a bunch of lighting rods at the time, so I just laid into them after that. It was a real setback.
I never bothered littering the world with stuff, and if I did, I would probably take it down now, because I value aesthetics over making a ton of money I'll never spend. I have a few crab pots on the ocean, since there are fish there I can't get otherwise, a chest on the beach, that I don't really need anymore, since getting all the teleport items, and a chest beside the ginger island warp location, which I like keeping my weapons in.
Past game year I was grinding for the clock so I went heavy into ancient fruit wine, but that's done now. The honey is more than enough money for everything I could possibly need, unless I wanted to buy a ton of endless fortune statues. Currently thinking about how I want to update my layout.
