In using an oil stove one should be used that will not smoke. Never set the roots over when the stove is first lighted and they should be removed before turning the flame out, as they are apt to get smoked. Do not set stove in a draft.
In packing the dry root in boxes I break off the fine fiber, then they are ready for market.
Some time prior to 1907, or since cultivated Ginseng has been upon the market, its value has been from $1.00 to $2.00 per pound less than the wild and not in as active demand, even at that difference, as the wild. Today the value is much nearer equal. At first those engaged in the cultivation of Ginseng made the soil too rich by fertilizing and growth of the roots was so rapid that they did not contain the peculiar scent or odor of the genuine or wild. Of late years growers have learned to provide their plants with soil and surroundings as near like nature as possible. To this can largely be attributed the change.
Preparing the Roots for Market.
The roots are dug in the autumn, after the tops have died. Great care is taken not to bruise or injure them. They are then washed in rain water, the soil from all crevices and cracks being carefully cleaned away by a soft brush. Then they are wiped on a soft absorbent cloth, and are ready to be dried for market. The roots should never be split in washing or drying. It is of great importance, too, that the little neck or bud-stem should be unbroken, for if missing the root loses two-thirds of its value in Chinese eyes. The roots may be dried in the sun or in a warm, dry room, but never over a stove or fire. Some growers have a special drier and use hot air very much on the principle of an evaporator. This does the work quickly and satisfactorily. As soon as the little fibrous roots are dry enough, they arc either clipped off or rubbed away by hand, and the root returned to the drier to be finished. The more quickly the roots are dried the better, if not too much heated. Much of the value of the product depends on the manner in which it is cured. This method is the one usually employed in America, but the Chinese prepare the root in various ways not as yet very well understood in the United States. Their preparation undoubtedly adds to the value of the product with the consumer.
Importance of Taste and Flavor.
Soils and fertilizers have a marked influence on products where taste and flavor is important, as with tobacco, coffee, tea, certain fruits, etc. This is true of Ginseng in a very marked degree. To preserve the flavor which marks the best grade of Ginseng, by which the Chinese judge it, it is essential that the soil in the beds should be as near like the original native forest as possible. Woods earth and leaf mold should be used in liberal quantities. Hardwood ashes and some little bone meal may be added, but other fertilizers are best avoided to be on the safe side.
When the chief facts of Ginseng culture had been ascertained, it naturally followed that some growers attempted to grow the biggest, heaviest roots possible in the shortest time, and hence fertilized their beds with strong, forcing manures, entirely overlooking the question of taste or flavor. When these roots were placed on the market the Chinese buyers promptly rejected them or took them at very low prices on account of defective quality. This question of flavor was a new problem to American buyers, for the reason stated and one which they were not prepared to meet at a moment's notice. Hence there has been a tendency with some exporters to be shy of all cultivated roots (fearing to get some of these "off quality" lots) until they were in position to test for flavor or taste by expert testers, as is done with wines, teas, coffees, tobaccos and other products where flavor is essential.
This mistake led to the belief with some that the cultivated root is less valuable than the wild, but the very reverse is true. It has been proven by the fact that until these "off quality" lots appeared to disturb the market and shake confidence for the time being, cultivated roots have always commanded a much better price per pound than uncultivated. The grower who freely uses soil from the forest and lets forcing fertilizers severely alone, has nothing to fear from defective quality, and will always command a good price for his product.
Ginseng should only be dug for the market late in the fall. In the spring and summer the plant is growing and the root is taxed to supply the required nutriment. After the plant stops growing for the season the root becomes firm and will not dry out as much as earlier in the season. It takes four to five pounds of the green root early in the season to make one of dry; later three green will make one of dry.
