Mulberry trees were treasured as a valuable fruit tree in the ancient civilizations, and the mulberries were collected for feeding families, fattening livestock and for feeding wildlife animals. Basically there are 3 color types of mulberries, black (Morus nigra), red (Morus rubrum) and the white (Morus alba), each type producing edible berries. The improved hybrid mulberrry tree cultivars are often grafted onto the red mulberry root-stock in order to dwarf the tree, making the trees easy to harvest and absolutely ideal for planting in small backyard gardens. Very often the grafted hybrid mulberry tree will bear the 1st year. Some mulberry tree cultivars produce juicy berries with enough sweetness and high sugar content that the mulberries can be ripened, dried and eaten later during the dormant season when tree-ripened berries are not available. Mulberry trees are self fertile, and consequently do not need cross pollination. The mulberry fruit size can vary greatly in size and flavor, but most berries grow to about one inch long, but the Pakistan mulberry can grow 5 or 6 inches in length, and are black in color.
