Crops: Do crops need to be watered? Can crops rot?

The crops don't actually need to be watered in order to grow, but your villagers will gain farming skill by planting and watering crops (which will help make them master farmers - something you'll need later). You can check how long until the next crop by clicking on the farm.

The crops don't actually rot, but if they are not all harvested before the next crops grow, they will be "wasted." The new crops will replace any crops that weren't harvested.
