People who have trouble with farmers, usually they havent gotten level 3 farming yet, once you have that they will go for fishing first and if theres any coconuts to pick then that, and then the garden, but no worries, its not like real life, the crops wont go bad, and when the recycle timer comes up, itll just send it back to 800 from what was left. relax, take a breath, no need to micromanage.
