Crops in the desert need plenty of water, so you should always make sure you plant them next to a well. You can equip the Watering Can using [Equip], fill it up at a well, then use it to water the crops. You can assign a character to do all this automatically (taking breaks to eat and sleep of course) by going up to some crops and pressing X to Farm.
