I believe that successfull planting in the late winter or spring depends on th condition of your seeds. If the embryo has pushed out the tiny tendril, it will be difficult to get the seed under some soil without breaking off the tendril which would kill that seed. You definately would not want to walk over the soil after the seeds are planted if the tendrils were sticking out of the seed shell.
Here's something I posted on Latt's 10 pound of seeds.
article from the state of KY:
\"When to Plant - Ginseng is usually planted in the fall from October until freezing weather
prevents further planting. Early spring (February/March) planting is also possible but
must be done before the seed starts to germinate. In northern areas where the ground is
frozen or cold and wet until April try to avoid spring planting. Handling seed that has
already begun to sprout often damages the young plant. Holding ginseng seed in a
refrigerator may delay germination for an entire year. I had some that never came up
whereas seed planted immediately did?\"
Picture of early sprouting seeds.

I would suggest getting the seeds into the ground before the tendrils start growing out of the seed shell.
