It's from an organic gardening site; I didn't garden that way but borrowed ideas from them.
Recharge your soil by using buckwheat as a cover crop
The author of Pleasant Valley (somewhere in Ohio) experimented in rebuilding depleted soil on farms. I think he used grass and let horses or animals graze but I don't remember exactly what all he did; it probably was clay soil which is harder to deal with.
Sorry about your dad. It sounds tough on everyone.
Yes it does , and it attracts deer , and maybe caribou too
But once the plant freezes, it becomes poisionous to deer , and the seed shatters .
