Also… stratified seeds (before planting) should be float tested first… just dump the entire bag of seed in a bowl of water…
Stir them a little… any floaters after 10 min should be descarded… they are bad.
The sinkers are likely good seed… but should be treated in a 10% bleach solution, 10 minutes, before planting.
You should also split open a few seeds to check for proper embryo growth… to verify they have been properly stratified… before you do those other steps.
I will go to my computer and send a pic to help you understand the embryo growth issue.
Here you go…

The seeds in the pic above, you slice them open, razor blade, along the seam, cutting them in half.
Inside you can see (if properly stratified) the embryo. the seeds above have been thru very nice stratification process, and the embryo is fully developed.
Now above is an example of seed where they simply were not stratified properly, the conditions just were not right… the embryo did not develop as they should. when you plant seeds like that, you will get poor if any results.
A little bit of food coloring will make the embryo development a little easier to see.
If you slice some seeds open and there is no embryo, or they are very tiny if found, that is a batch of seed you should return to the vendor for a refund. Simply not stratified properly… or may not have been stratified at all.
Green Seed - has not been stratified at all, and some (less than honest seed sellers) will sell you green seed, as stratified seed… Back around 2014 2015 there were several out there doing that… the only way to confirm that your seed has been properly stratified, is by checking them yourself… Examples above.
Ok found one other pic that you might find helpful…
The pic above shows some GOOD stratified ginseng seed. If you will notice, several of them, are starting to split open (along the seam) and there is some white showing, where that embryo has grown and is starting to cause the seed to split open, and some will even have little tails hanging out (the start of root heading out)… They call that tailing…
A GOOD batch of seed will look like that.
Also notice the color of the seed… that is the right color there.
If you let them dry out, they will get much lighter, almost white… when keeping them in cool storage (perhaps for a week or so, while planting a large batch)… you need to keep them moist (so they keep that nice color)… and don’t let them dry out and turn white.
Best of luck to you.
