We are on the hills between Emilia-Romagna and Tuscany (Italy). Our altitude is pretty high, 900 meters, so winters are cold (also -10°) but summers can be hot (no more than 30°).
This is my first time having a garden on the hills, as I usually have it in the plane of Modena (very hot and humid weather, perfect for tomatoes and melons).
So... it's an experiment, as the no dig method. At the moment, I find it's a beautiful way of growing vegetables and the garden is healthy and doing well.
