Paths and fences can be used in the game to decorate the farm and to separate zones. For example, they can help you to make separate zones for plants, for production buildings and for animals.
You can lay paths and build fences on your farm starting from level 7. You can find and acquire them in the construction menu under the tab with the fence image on it:
To place a path or a fence on your farm land, select it in the menu and drag it to the desired location, marking the starting point of your path or fence. Use arrows to navigate and set the direction and length:
If you decide to make a rearrangement on the farm, you can put them into storage or remove them. To do that, tap on the path or fence, hold for 1-2 seconds and use the arrows to navigate (the green arrow - add a new section, the red arrow - remove the section):
Removed paths and fences are kept in your storage, so you will be able to use them next time when you need to build a new fence or lay a path on your farm.
