Most people dont realize all the factors that affect the price. Cultivated seng, burnt woods seng, dirty seng, wet seng. It is easy to cultivate a patch in the woods using wild berries, but it takes years for the planted seng to grow. Earlier I didn't mean to come on like a know it all. But I have been digging over 50 years, a lot of what I have learned has been passed down by older generations, (grandfather, father, and an array of older men who dug). There information isnt scientific, or technical but it has served me well. As was stated by petronias earlier, it gets you out.
