On a light note, if I may relate my own experience regarding Potato growing:
Some years ago husband and I tried our hands at this. We bought a bag of beautiful seed potatoes and decided to grow them in a nice corner in our backyard. Now this corner had super rich soil, it was years ago a small in- ground pond for Waterlilies and Lotus and when we dismantled it, we filled up the hole with leaves in the Fall. Several years later - here came the potatoes ( and also Tomatoes, but that is another story
)
Growing up in East Germany, where so many people grew their own food in those years, we remembered the small hills of soil surrounding each plant, and we knew that harvest time came in the Fall, when the green plants had died down.
Well, the potatoes started to produce green tops and bloomed very nicely! And the plants grew and grew!! Ohh, they grew very well, they engulfed the whole corner!!
Then came Fall, we waited for those darn plants to die down already, but no, they still grew and bloomed happily. It must have been a warm Fall.
Finally, we pulled up the plants and happily harvested!
ONE SMALL POTATO!!
I want you to know, I planned a whole meal around it with this potato as the center piece, set the table properly with candles, the whole works, surely you can picture this?
We shared that potato properly as we took it apart daintily with knife and fork.
Lesson learned, surely the soil was way too nitrogen-rich and in future years I stuck to growing Orchids and C&S .
