There is no way to make the Ranch larger. You have rearrange things, sell things and squeeze everything as close together as possible. I usually have 15 of each plant, 3 cows, 3 sheep, 3 ostrich and 6 hives, plus all the machines. I run all the crops north and south on the west edge and my farm bumping up against each other with hole in the middle for a sprinkler. Run the hives in 2 columns of 3 against the east edge. Then squeeze everything together in the middle. If you have a problem, reply or send me a message and I'll get a screenshot of my layout.
