Growing Plants
People who live in an oasis must manage land and water use carefully; fields must be irrigated to grow plants like dates, figs, olives, and apricots. The most important plant in an oasis is the date palm, which forms the upper layer. These palm trees provide shade for smaller trees like peach trees, which form the middle layer. By growing plants in different layers, the farmers make best use of the soil and water. Many vegetables are also grown and some cereals, such as wheat, barley and millet, are grown where there is more moisture.

Famous quotes containing the words growing and/or plants:
“Hardly ever can a youth transferred to the society of his betters unlearn the nasality and other vices of speech bred in him by the associations of his growing years. Hardly ever, indeed, no matter how much money there be in his pocket, can he ever learn to dress like a gentleman-born. The merchants offer their wares as eagerly to him as to the veriest “swell,” but he simply cannot buy the right things.”
—William James (1842–1910)
“Probably if our lives were more conformed to nature, we should not need to defend ourselves against her heats and colds, but find her our constant nurse and friend, as do plants and quadrupeds.”
—Henry David Thoreau (1817–1862)
