Thank all of you Permies for the replies. They were very helpful
Buckwheat, comfrey, dandelion....those are all great!
I spoke with the local conservation office yesterday. They are offering incentives for people to naturalise their outdoor areas. They would cover the areas that I want to recreate a natural area. We talked mostly about planting a forest. I would be able to choose what types of plants/trees are put in.
In this area b. clay is thought to be a hinderance. There is a lot of agriculture in the surrounding areas. Mostly there are tomatoes, vineyards (on the wine route), orchards, but A LOT of greenhouses.
I have never lived in an area where soil was such concern. Growing up in Appalachia it always seemed....there is Earth and it was all good! Different place and this is new to me.
Thanks again all. Will keep watching the thread.
