I had a vegetable plot for a couple of years. Really heavy duty digging up old nettle roots all over it. Putting old horse manure and sand on it. The soil was the blue kind of clay you find on the bottom of the sea here. 173 square meters too.
Those were the best years I recall ever. I moved to a different house, so it was too far away and I had to give it up. Here I do have a sunny backyard but for several reasons never got around to doing it here. Was just thinking about it a lot lately to finally do it this spring/summer.
