Dates grow on date palm trees (Phoenix dactylifera), one of the oldest cultivated fruit crops on Earth. These trees thrive in the hot, arid regions of the Middle East and North Africa, where they’ve been farmed for thousands of years. In 2023, the world produced 9.82 million tonnes of dates, with every one of the top eight producing countries located in that same belt of desert climate.
The Date Palm Tree
Date palms are unusual fruit trees. They’re dioecious, meaning there are separate male and female trees, and only the females produce fruit. The trees need a long, intensely hot summer with little rain and very low humidity between pollination and harvest, but they also need plenty of water at the roots. An old saying captures this perfectly: the date palm grows with “its feet in the water and its head in the fire.”
The trees can tolerate average temperatures ranging from about 13 to 28 °C, survive extremes up to 50 °C, and handle brief frosts down to roughly -5 °C. They’re also relatively tolerant of salty and alkaline soils, which makes them well suited to desert oases and irrigated valleys where other crops would struggle. A date palm takes years to mature from seed to fruit-bearing age, and the trees are long-lived, sometimes producing for a century or more.
Where Dates Are Grown Today
Egypt is the world’s largest date producer, growing about 1.87 million tonnes in 2023. Saudi Arabia follows with 1.64 million tonnes, then Algeria at 1.32 million tonnes. Tunisia and the United Arab Emirates round out the top ten. The entire top tier of producing nations sits in a band stretching from Morocco across North Africa and through the Arabian Peninsula into the Persian Gulf.
The United States grows dates too, though on a much smaller scale. Spanish missionaries first brought date seeds to the New World during the colonial era, planting them around missions in Mexico and eventually southern California. The humid coastal climate proved poor for fruit production, but the scorching interior deserts were ideal. Between 1876 and 1890, offshoots were imported from Egypt, Muscat, and Algeria and planted experimentally in the hot valleys of the American Southwest. A U.S. Department of Agriculture date experimental station opened in California’s Coachella Valley in 1904, and by 1957, that single valley accounted for 85 percent of all U.S. date acreage.
Thousands of Years of Cultivation
Date palms rank among the earliest domesticated fruit crops. In the Nile Valley, date palms were present during the predynastic period roughly 5,000 years ago, though large-scale cultivation in Egypt didn’t take off until at least 3,500 years ago during the New Kingdom. Archaeologists have recovered date palm seeds from sites in the Southern Levant (modern-day Israel and Jordan) radiocarbon dated from the fourth century BCE to the second century CE. Remarkably, seven of those ancient seeds were successfully germinated in modern labs, producing viable plants from 2,000-year-old material.
The crop spread westward more slowly. Date palm remains in Libya are dated to about 2,800 to 2,400 years ago, and the fruit didn’t reach the Saharan Maghreb and sub-Saharan Sahel until considerably later.
How Dates Are Pollinated
Because male and female flowers grow on separate trees, dates depend on pollen traveling from one tree to another. In the wild, wind handles this. But wind pollination is unreliable, so commercial growers pollinate by hand to ensure a good harvest. Workers climb the trees and place strands of male flower clusters directly into the female flower bunches. This traditional method is still the standard on most farms worldwide, though it requires experienced labor, takes significant time, and uses roughly double the pollen compared to newer techniques involving dried pollen applied mechanically.
From Flower to Fruit: Ripening Stages
Dates don’t just go from green to ripe. They pass through distinct stages, and people actually eat them at different points depending on preference and variety.
- Khalal: The first ripening stage. Dates are firm and crisp, brightly colored in yellow or red, with a mild sweetness. Some varieties are eaten fresh at this stage.
- Rutab: The fruit softens, turns brownish, and becomes juicier and noticeably sweeter. The texture is tender.
- Tamar: The final stage. Dates are fully dried, deep brown, wrinkled, and intensely sweet, with concentrated sugars that make them ideal for long-term storage. This is the stage most people picture when they think of dates.
Harvesting Is Still Mostly Done by Hand
Date palms can grow quite tall, and the vast majority of date harvesting worldwide is still done manually. A harvester typically wraps a rope around his back and the tree trunk, then climbs up to reach the fruit clusters hanging near the crown. Once at the top, the harvester may pluck fruits individually, shake bunches to knock ripe dates loose, or cut entire bunches when they’re ready. The work is physically demanding and genuinely dangerous, with falls from height a constant risk.
Some operations use ladders for shorter palms or hydraulic lifts for taller ones. Saudi Arabia in particular has experimented with industrial machinery, including robotic arms and even drone-based systems equipped with precision saws to cut date bunches remotely. But these technologies remain limited in reach and adoption. For most of the world’s date crop, the process looks much the same as it has for centuries.
Common Varieties
There are hundreds of date varieties, but two dominate grocery store shelves. Medjool dates, originally from Morocco, are large, dark, sticky, and soft with a rich caramel-like flavor. They’re often called the “king of dates” and tend to be more expensive. Deglet Noor dates, grown widely across the Mediterranean and in California, are medium-sized with a translucent, lighter color and a subtler taste often compared to brown butter and cashews. They’re firmer and drier than Medjools, making them a popular cooking ingredient.
Nutritional Profile
Dates are essentially a sugar delivery system wrapped in fiber. The flesh is low in fat and protein but rich in fructose and glucose, providing roughly 314 calories per 100 grams. That same portion contains about 8 grams of dietary fiber, mostly the insoluble type that supports digestion. This combination of dense energy and high fiber is part of why dates have been a staple survival food in desert cultures for millennia: they’re calorie-rich, portable, and in the tamar stage, they keep for months without refrigeration.
