My question is how long can I wait after picking them before I replant them closer to home. I don't want them to dry out and become usless. What should I do to preserve them at least a week or two before I can replant them with my other gensing that is growing there.
I'm guessing this late reply may now be time redundant. But here is an answer to your question above.
The seeds will be well protected and kept moist inside the berries. You will have plenty of time (given your week or two time frame you mention) to plant the berries with your other Ginseng. Do note at this point your seeds will not produce seedlings in the spring, it will be the following spring that you should look for seedlings.
