The rapidity of growth of this shoot is a marvel of tropical hustling. A prominent naturalist has made a record of the growth during the first few hours which seems almost incredible, but is true. Twenty minutes after the stalk was cut, the new shoot could be seen pushing up from the center of the cut. Eight hours after cutting, the shoot was nearly two feet in height with the leaves forming. Thirty-one hours after cutting there were four well-developed and perfect leaves and the new shoot constituted quite a respectable looking tree. This great rapidity of growth is due to the spirally-wrapped leaves that are contained within the banana stalk, and which are merely pushed upward and unroll. It is a fact that under those circumstances the growth is so rapid that it is almost discernible to the eye. Stalks grown in this way, it is said, seldom bloom or bear fruit. The requirements for successful cultivation of this fruit are a deep, alluvial soil, and plenty of water either by rain or irrigation. The nature of the soil, however, seems to have less to do with the successful growing of the banana than the amount of rainfall, which should be at least one hundred inches annually, and the temperature, which must be very warm. The best results are obtained near streams, and an occasional overflow is not a disadvantage. About two hundred or two hundred and twenty-five hills to the acre is the usual allowance. The average yield will then be from two hundred and fifty to three hundred bunches of marketable fruit each year. It is practically immune from insect pests, and a worm-eaten banana, or banana stalk, is practically unknown. It is so vigorous that it will hold its own amid all sorts of weeds and climbing vines, although the successful cultivator will keep his fields free from such pests.
