Potatoes are growing nicely, there are even flowers this year.
Both coloration of the flower indicates two different species here, I know because I planted two kinds of potatoes.

@mangeurdenuage Growing potatoes yourself rocks. Sad that my garden has bad soil for growing anything

Why kind of soil do you have ?
Mine was inadequate too. It was mostly backfilling of rocks and similar. The few centimeters of fertile soil was there because it formed over the past seven decades, otherwise just rocks.

Last year I had to start with raised beds and add composted material into them and grow in a few square meters.

This year I doubled the surface of the raised beds and removed all the grass and other plants by putting a large amount of woodchips.

Soil composition is important if you want to maximize as much as possible growth of certain vegetable, but that's kinda reserved to very dedicated people or farmers. In general if you stay with good compost, woodchip mulch and a touch of compost tea you'll have satisfying results.

If you want a bit of information before starting anywhere I'd recommend to watch the "Back To Eden Gardening Documentary"

and then read "Teaming with Microbes" which I added in this post.
I cannot highly recommend enough to read this book, it's a must if you want to do a veggie garden and avoid a lot of pain.

@mangeurdenuage @giru

you could try different plants. i have a really sandy and sour soil here, potatoes, fava beans, and miners lettuce are doing well, everything else not so much. my pumpkin/squash is barely growing, corn is only doing okish. my onions and tomatoes aren't doing so well either. fava beans have the perk that they fixiate nitrogen.
