I can't remember how I changed it to a white background! I want it to go back to being green for spring.How do I change my Farmville background from snow (white) to grass (green)?
Go to the market. It is in the same section as expanding your farm. I forgot about changing my fields back to grass and had snow for quite a while! :)How do I change my Farmville background from snow (white) to grass (green)?
ok first make sure you have 1,000 coins. go into farmville and go to market, then to upgrade farm, it will be called Green Pastures and it should be on the first page.
