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.

[Illustration: COFFEE GROWING UNDER SHADE, PORTO RICO] 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. In preparing the soil for the new plantation under the intensive cultivation method, the surface of the land is lightly plowed, and then followed up with thorough cultivation. When transplanting time comes, which is when the plant is about a year old, and stands from twelve to eighteen inches high with its first pairs of primary branches, the plants are set out in shallow holes at regular intervals of from eight to twelve, or even fourteen, feet apart. This gives room for the root system to develop, provides space for sunlight to reach each tree, and makes for convenience in cultivating and harvesting. _Liberica_ and _robusta_ type trees require more room than _arabica._ When set twelve feet apart, which is the general practise, with the same distance maintained between rows, there are approximately four hundred and fifty trees to the acre. In the triangle, or hexagon, system the trees are planted in the form of an equilateral triangle, each tree being the same distance (usually eight or nine feet) from its six nearest neighbors. This system permits of 600 to 800 trees per acre.
