Cultivation
Datura prefers rich, calcareous soil. Adding nitrogen fertilizer to the soil will increase the concentration of alkaloids present in the plant. Datura can be grown from seed, which is sown with several feet between each plant. Datura is sensitive to frost, and so should be sheltered during cold weather. The plant is harvested when the fruits are ripe, but still green. To harvest, the entire plant is cut down, the leaves are stripped from the plant, and everything is left to dry. When the fruits begin to burst open, the seeds are harvested. A single intensively planted acre can produce 1,000 to 1,500 pounds (1,100–1,700 kg/ha) of leaf and 700 pounds (780 kg/ha) of seed.

Famous quotes containing the word cultivation:
“Those who are esteemed umpires of taste, are often persons who have acquired some knowledge of admired pictures or sculptures, and have an inclination for whatever is elegant; but if you inquire whether they are beautiful souls, and whether their own acts are like fair pictures, you learn that they are selfish and sensual. Their cultivation is local, as if you should rub a log of dry wood in one spot to produce fire, all the rest remaining cold.”
—Ralph Waldo Emerson (1803–1882)
“We Russians have assigned ourselves no other task in life but the cultivation of our own personalities, and when we’re barely past childhood, we set to work to cultivate them, those unfortunate personalities.”
—Ivan Sergeevich Turgenev (1818–1883)
