Lets touch base late this summer and I will send you some seeds for both. Both Goldenseal and Blootroot seeds need to be planted 1/4 inch below the soil surface in areas where ginseng grows well. They will take two seasons to come up just like ginseng seed if it is not stratified. I plant them both like I do ginseng seed with the raking, scratching them in, and then re-raking the leaves back on.
The seeds are small and it's important not to put too many per square foot as they will spread out when they grow unlike ginseng. 1 oz of goldenseal and bloodroot seeds go a long way. By the way it's OK to rake a 5 x 5 foot spot and sow some seeds and then pick another spot to plant a 5 x 5 spot and so on and so on. They will spread out nicely and do not need to be planted in long rows. How about Black Cohosh fellas. Does it spread like goldenseal and bloodroot or is it more like ginseng?
