Storage

Added November 19 2009, Tool sheds and Barns now allow you to store unused items. Tool Sheds purchased with coins store 2 items where Barns store 6. Tool Sheds purchased with cash store 15 items and Barns store 20.

If you need a lot of storage but don't want to take up much space you either need to buy using cash or use Tool Sheds. Tool Sheds store 8 items in the same space as a Barn stores 6.

Storage can now be expanded on every unit. You can add 5 storage to any storage building(barns and tool sheds). By having a barn raising. You will be given 3 days to get 10 friends to help you by clicking on your facebook news feeds. If you fall short you can spend one farmcash per missed person to get the upgrade anyway.

Plowing

Plowing gains 1 XP regardless of what you plant any unused piece of ground can be used.

Unlike Farmtown your neighbors and friends cannot help you plow.

Using a tractor allows you to plow larger swathes of land. However they require fuel and fuel can only be purchased with cash not coins or you can wait for it to refill. It refills at the rate of one per 2 minutes. Each fuel unit allows you to do one thing to one square of grown.(Plow, Harvest, or Seed)

If you build a fence around yourself your character won't walk to the different squares and will plow much quicker. But a better Farmville tip is to watch where your character pops up on the screen. At that point put 4 hay bales around him/her. This will make it so your character can't move. This cuts down on the time spent walking from one square to the next.

Planting on Farmville

You can either chose the multi-tool and click on any piece of plowed land which will then pop up the market where you will need to select the type of seed you want to plant. Then it will plant that type of seed on that open plowed area. Once you do this you can then keep clicking on plowed areas and planting the same type of seed.

You can also start planting by clicking on the marketplace and then selecting a type of seeds. Then clicking on any open piece of plowed land.

It's very important to choose which type of seed you want to plant by your ability to get back in time to harvest it. Just because you can make the most money early on by doing strawberries doesn't mean you will. Strawberries have to be picked every 4 hours. If you fail to get back to them before they go bad you'll be out the money for plowing and the seeds.
