I moved to a new house last year. (Belgium, doesn't follow the weather of the zoning system well) We are in the process of stripping it down to the bones, just got a new roof, have to dig out the floor down 35 cm to pour a cement slab, etc...
Suffice to say I don't have the time for a garden this year even though we have a lovely 1500m^2 plot with around 60 trees that haven't been upkept for years.
I would love to know some super easy low upkeep plants to help the soil in our future garden bed areas (one used to be a big compose pile, so the soil there seems pretty good already).
I was thinking some potatoes in the method of loosening the soil, throwing a ton of seed potatoes and maybe onions over it, and covering it with a bunch of dead grass cuttings that we have.
Then maybe some bush beans too. If it is a wet year like the winter it has been, they should grow very well.
