Fresh cuttings should be planted after the second ratoon since the yield per acre diminishes rapidly after that. In the grapefruit group are the Marsh Seedless, the standard variety grown for export, the Silver Cluster and Duncan which contain many seeds, the Ugli, chiefly exported, and the Chadwick . Rocky hillsides with shallow soil exposed to erosion should be avoided. In preparing the land special consideration must be given to the avoidance of pests. The trees should be protected from prevailing winds and, if there is no natural shelter such as a mountain range or a belt of forest, windbreaks should be established before the orchard is started.
Propagation is by budding.
Bananas Bananas are cultivated in nearly every moist tropical country, and constitute a substantial part of the local diet. Jamaica is one of the leading banana-exporting countries in the world. Deep loam with a fair proportion of sand is the best type of soil for banana cultivation. The water requirement of the banana is very great. Whereas St. Mary and Portland with their abundant rainfall provide excellent banana lands, the St. Catherine plains have to be extensively watered by artificial means to grow bananas.
