Tropico 6 Plantation and buses

Hello all,

Apologies as I am sure this has been asked before.

I have just picked up T6 for a new laptop I recently had to buy. Getting to grips with the game but I have seen some layouts of Plantations and I thought you should always put them in the areas where they are as green as possible, but some people seem to all lay them in the same area regardless.

What basic thing should I be doing for my plantations to try and max efficiency regarding lay outs?

Also do you create homes near by or use car parks and/bus routes for people to get there?

Many thanks.
