Crops in FarmVille will wither if they are not harvested in time. If a plant withers, you can only plow it rather than harvest it. Therefore the farmer will lose potential experience and no coins for plowing the crop.
All crops on FarmVille will wither 2.5 times their growing time. For example a 4 hour crop will wither in 10 hours.
4 hours x 2.5 = 10 hours before withering.
- 4 hours to grow.
- 4 hours of ripeness.
- Up to two more hours of ripeness. At any time during this period, the crops may wither.
When technical difficulties prevent users from successfully loading FarmVille for extended periods of time, Zynga turns off the withering feature and restores withered plots so farmers do not lose their crops. This will also bring your unfed puppies back from the pound.
