CULTIVATION OF THE COFFEE PLANT Page 2

In Mexico, Romero tells us, the highlands of Soconusco have the advantage that the sun does not shine on the trees during the whole of the day. On the higher slopes of the Cordilleras—from 2,500 feet above sea-level—clouds prevail during the summer season, when the sun is hottest, and are frequently present in the other seasons, after ten o'clock in the morning. These keep the trees from being exposed to the heat of the sun during the whole of the day. Perhaps to this circumstance is due the superior excellence of certain coffees grown in Mexico, Colombia, and Sumatra at an altitude of 3,000 feet to 4,000 feet above sea-level.

Richard Spruce, the botanist, in his notes on South America, as quoted by Alfred Russel Wallace,[315] refers to "a zone of the equatorial Andes ranging between 4,000 and 6,000 feet altitude, where the best flavored coffee is grown."

Propagation. Coffee trees are grown most generally from seeds selected from trees of known productivity and longevity; although in some parts of the world propagation is done from shoots or cuttings. The seed method is most general, however, the seeds being either propagated in nursery beds, or planted at once in the spot where the mature tree is to stand. In the latter case—called planting at stake—four or five seeds are planted, much as corn is sown; and after germination, all but the strongest plant are removed.

Where the nursery method is followed, the choicest land of the plantation is chosen for its site; and the seeds are planted in forcing beds, sometimes called cold-frames. When the plants are to be transplanted direct to the plantation, the seeds are generally sown six inches apart and in rows separated by the same distance, and are covered with only a slight sprinkling of earth. When the plants are to be transferred from the first bed to another, and then to the plantation, the seeds are sown more thickly; and the plants are "pricked" out as needed, and set out in another forcing bed.

During the six to seven weeks required for the coffee seed to germinate, the soil must be kept moist and shaded and thoroughly weeded. If the trees are to be grown without shade, the young plants are gradually exposed to the sun, to harden them, before they begin their existence in the plantation proper.

Considerable experimental work has been done in renewing trees by grafting, notably in Java; but practically all commercial planters follow the seed method.

Preparing the Plantation. Before transplanting time has come, the plantation itself has been made ready to receive the young plants. Coffee plantations are generally laid out on heavily wooded and sloping lands, most often in forests on mountainsides and plateaus, where there is an abundance of water, of which large quantities are used in cultivating the trees and in preparing the coffee beans for market. The soil most suitable is friable, sandy, or even gravelly, with an abundance of rocks to keep the soil comparatively cool and well drained, as well as to supply a source of food by action of the weather. The ideal soil is one that contains a large proportion of potassium and phosphoric acid; and for that reason, the general practise is to burn off the foliage and trees covering the land and to use the ashes as fertilizer.
