The last two posts here make the point elegantly: sweet potatoes enjoy the warmth of SE London but not the cool of a Welsh hillside.
Even here in mild (but rarely hot) Somerset, they grew poorly. It’s good to try things and I always encourage that but for the main part, and to eat well, I find it most worthwhile to grow the staples: veg that are traditional to my region.
And with no dig, that is easier and gives good yields.
