There are a lot of things we see as we look for ginseng or tend to our plants. If we are observant, we can fill in off season (generally late summer) by producing some of these other herbs that are in demand.
Bloodroot is up a little right now. I've been telling guys to wait until later in the summer to dig it....let it seed and it also loses a lot of its moisture so you won't have as much trouble with mold.
I can't take anything with dirt or mold, but I could deal with you via mail if you like. I have a full pricelist posted on my site.
I don't know for sure, as I've never dug either to dry. I would imagine when we get a little farther along in the spring for the bloodroot (maybe not for mayapple) you will dry close to 3:1. I'm just speculating, I don't know for sure.
If I had to guess how many average bloodroot roots were in a dry pound is this area I would guess maybe 50-100.
