To purchase your second farm, go to the Market & click "Development".
Choose "Farm #2" for 20 gems.
From your first farm, you will see on the left side of your screen a small farm icon above the "+" and "-" buttons. Click on the box to access/see your new farm.
Your second farm will show up as a 12 x 12 farm, the same size as the original farm when you started the game. It will be attached to the upper lefthand corner of your first farm.
As you switch between farms, the game will show your farms as ready to harvest, even if they aren't, until the farm you are moving to has completely loaded. You will also notice that your "ground" turns a pale shade of green when you click the "switch farms" button. The pale green ground is your choice cursor to choose the farm you want to be on. You can use your tool shovel to move the "cursor" to the farm you want to work on, then click once & that farm will load.
Your task bar will work the same way on your Second Farm as it does on your first farm. You can create planting plots & ponds, expand your farm with coins or gems and use the Market to buy things for your Second Farm the same way you do on your first farm.
Activities completed on the Second Farm will also count toward your crafts. So, if you catch butterflies or harvest strawberries, etc., those activities will count toward your crafts if you need them to complete a craft.
You can also earn XP on your Second Farm from people watering your crops. Crops planted on your Second Farm can be processed in the factories on your First Farm, so you don't have to buy two of everything.
You can purchase items (buildings, construction sites, decorations & animals) to place on your new farm, plus you can use items from your current storage and/or you can move items from your First Farm onto your Second Farm. To move items from your First Farm to your Second Farm, click on the blue arrow cross on your task bar right after you click on the box that transfers you between your farms (while the farm still has the pale green ground).
You can visit your neighbors' Second Farms by going to their First Farm, then clicking the new land icon on the left side of the page. When visiting, you can also water their crops & click on any constructions on their Second Farm.
