Do I save all my Money or spend it?

There are not set rules as far as spending your money and using your land goes with Farmville. Each and every item benefits you in some way, with the experience points that you get. So whether your choice is based on what will benefit the farm most, or simply what you like the most, it doesn’t matter; it is entirely up to you. The only slightly tricky part is deciding what to buy, it is wise to budget and figure out how much of your money you would need to put away to buy a particular item, spending all you money after each harvest will not get you anywhere fast.
