Growing medjool dates is very labor intensive. It requires an awful lot of labor and the medjool date palms require a lot of water. The medjool date is grown in hot deserts. The watering is done by flooding or by drip. Most modern farms use a drip system to conserve water and reduce the operating expense. The problem with drip is that if there is a clog you might know about it until the date palm is dead. The cost is about $200-500 a date palm. Why are medjool dates expensive ? This is one reason.
