The new idea is to fall. That seed needs to come out of the stratification box apply gypsum (Calcium sulphate) to soils for ginseng and into the soil after 12 months. If the seeds are left in rather than lime (Calcium carbonate) which has been used stratification for a longer time to accommodate spring in the past. The reasoning behind this is that the gypsum planting, the seeds will sprout inside of the stratification will add calcium but will not raise the soil pH. Rates as box and will be useless. Some growers make the mistake high as 5 pounds of gypsum per 100 square feet of of planting ginseng seeds in September and in October growing bed have been recommended to bring the before the trees lose their leaves. The problem with this calcium levels up to 4000 pounds per acre. There are practice is that the falling leaves form a mulch on the strong suspicions among several ginseng experts that forest floor that may be too deep for the germinating ginseng diseases, like Phytophthora root rot, may be ginseng seedlings to grow through. Fall planted seeds lie suppressed by acid soil conditions. There are strong in the soil until the following April. When they suspicions among the same group that applications of germinate, they can grow up through an inch or two of lime to bring the soil pH up may lead to increased disease leaves but they cannot grow up through four or five inches problems. Unfortunately, these suspicions have not been of leaf mulch, which may accumulate in many sites from tested by replicated research studies. A few concerns about heavy applications of gypsum have been voiced bysoil scientists. They are worried that growers may throw There are presently about 20 commercial sources of the soil fertility out of balance if they apply too much American ginseng seed. Most seed is sold by experienced gypsum. Clearly, controlled research studies need to be ginseng growers, who have developed large-scale ginseng farms. Beginning growers should be cautious in buyingginseng seed. Most experienced growers have bought The other soil nutrient that ginseng growers should seed at one time or another that failed to germinate in the monitor is phosphorus. In 1978, Dr. Tom Konsler spring after fall planting. Growers are advised not to buy initiated a four-year study to measure ginseng root growth cheap seed. It is rarely a good deal. A great deal of response to P additions to the low P soils found at the meticulous care is required to successfully produce Mountain Horticultural Crops Research Station in viable, stratified ginseng seed. Seed producers, who do Fletcher, N. C. Dr. Konsler found positive correlation of the job the right way, are not likely to sell their seed at root weight with phosphorus additions. He also found cheap prices. Most seed producers do like to sell their that ginseng plants took up calcium more readily in soils stratified seed in advance. To be assured of the best seed, that had available phosphorus so the interrelationship is growers should order and pay for ginseng seed in July or important (Konsler, 1990). Growers should amend their August. Once the seed is paid for, delivery can be low P soils so that at least 95 pounds per acre of actual postponed until the middle of October. Growers who wait phosphorus is available (Persons, 1994).

When purchased ginseng seed is received, it soil. Many persons recommend planting “woods grown” should be stored in the refrigerator.
