I don’t know of any milkweed drop-off locations for Geauga County. We do take milkweed seed donations at Geauga Park District, though, for use in giveaways at the fair and at the nature center. If you do want to donate seeds to the park, please de-seed the pods (open the pods, grab the silk at the tip, and scrape the seeds off with your other hand), place the removed seeds in a paper lunch bag, and bring them to The West Woods. We will store them in our freezer over the winter and then use them next year for giveaways. I just created this YouTube video demo on how to collect the seeds in case it is helpful.
Thanks for asking!
