Plant Cultivation: Job's tears (Coix Lacryma-Jobi) is a close relative of corn and can grow to 4 feet. Since ancient times this grass has been in cultivation as an especially sweet-tasting cereal flour but it also has the distinction of being the oldest ornamental grass in cultivation—it was grown in the fourteenth century in monastery gardens. The seeds fall readily from the plant cultivation at maturity and are extremely hard, colored with streaks of gray and black on white.
GARDEN, gar'd'n, a piece of ground for the cultivation of plant cultivations, fruits, or vegetables, generally adjacent to a dwelling. The term also includes public gardens and commercial truck gardens. The subject covers so wide a range that the technique of every branch of gardening cannot be dealt with specifically and in detail in one article. Certain principles, however, may be established. These, with suitable modifications, are applicable to the cultivation of trees, flowers, vegetables, small fruits, and indoor horticulture whether in the home or the greenhouse. The subject is dealt with under the following headings : history, general principles, plant cultivation enemies, propagation, house plant cultivations, and equipment.
Cultivation. Cultivation is an ancient vineyard practice. It destroys weeds and facilitates other vineyard operations such as irrigation. Contrary to common belief, cultivation does not conserve soil moisture; however, the resulting destruction of weeds does conserve moisture. Discs or chisel-tooth cultivators are used, although some vineyards are still plowed. Heavy disc harrows are used to turn under weeds and cover crops. Weeds have been and are sometimes controlled with oil sprays or chemicals, usually diuron or monuron. |
