How do you fertilize other farms on farm ville?
You can fertilize farms only if you are one of the selected players that receive that option. When you go to visit your neighbors’ farms, after you help them a little bag called ‘Super Grow’ with a x5 next to it will appear in the bottom left corner. Click on it and click some squares in your neighbor’s farm. The squares will start to sparkle. This gives your neighbor a bigger sized crop of that type and more experience points when they harvest.
