To me companion planting is cheaper than pesticides,less work than dragging out wild plants,wish I could digest fibre, I love it ,but I can't ,what root vegetables are indigenous to North America ?,we have turnip(swede),leeks, in n.e.England,also green beans have a lot of tryptophan (happy chemical)along with peanuts,wow if only Bob that cares for the pet goose could get to Oregon, that goose loves!!! Kale and corn I've never seen corn stripped within an inch of its life and watermelon ,Bob feeds everything and George makes sure he gets some of whatever he puts out,he's going to plant an orchard when he gets manure ,somebody sold all of the top soil,before he bought the land.
