The date palm (Phoenix dactylifera) is a North Africa native. The tree doesn't do well in cold weather and the fruit grows best in warm, dry regions. When grown in the proper environment, such as Arizona and southern California, the date palm can reach 100 feet in height with a canopy width of up to 40 feet. The female plant, if there is a male nearby, will bloom in the spring and produce dates that can be harvested in the fall. The date palm tree requires full sun and regular irrigation. It is hardy to USDA Hardiness Zones 9 to 11.
Soak the date palm seeds in a cup or bowl of water for three days. Change the water daily.
Pour equal parts of coarse sand and vermiculite into the plastic container and mix it together well. Dribble 2 tbsps. of water over the surface of the soil and mix it again. The soil should feel almost dry. Too much moisture will cause the seeds to mold.
Push the seeds into the planting mix until they are completely covered. Cover the container and place it in an area that remains very warm: The ideal temperature is 90 degrees Fahrenheit.
Check the seeds frequently to make sure that the soil remains moist. Also check for any seeds that have begun to sprout. Remove those and place them, one inch deep, in a pot filled with equal parts of coarse sand and potting soil, moistened. Keep them warm until they sprout.
Pot up, in the same manner, the other seeds as roots begin to appear. Do not over-water; keep the soil just barely moist. Place the pots in a warm, well-lit area (at least 75 degrees Fahrenheit), free of drafts.
