Ok, so our marsh went through a small drought earlier this year, and we have an abundance of Polygonum pensylvanicum, aka, pink smartweed. I've seen some of you folks try to plant this stuff. Do you physically just take the seed heads off of the plant and just scatter it out? What's the max depth that I can disperse these seeds in? I'd like to try to get it more established in certain areas. Thanks in advance.
