I've had horrible success with pots. I planted some in a pot and nothing came up at all. Then I went and planted some Poncirus Trifoliata in the same pot (without even changing the dirt) and they all came up great. So I'm thinking Ginseng doesn't like pots.
The seeds come up great but dye quickly for some unknown reason. I have tried it many times. It just doesn't work.
Here are some pics of some small rootlets that I planted three years ago.They sprouted great but did not make it indoors either. They died even though they were given the right amount of water and light.
