Here you will learn how to earn FarmVille cash faster. If you want to earn extra FarmVille cash through speeding up your planting and harvesting times, follow these steps: Buy 4 fences and make a box out of them. You need to do this at the FarmVille spawn point. (dead center of your farm). You will now be able to complete actions faster because your FarmVille character won't have to move around to plant/harvest.
