Is my soil wrong for carrots?

[Lämmchen]

I hadn't thought about using pots. We have a lot of garden space so I just did that. The other vegetables we had were tomatoes, zucchini, cucumbers, broccoli, beans, onions and some herbs. The only other plants that failed were the onions and broccoli. The broccoli were in the flood zone of the garden and I need to fill that in this year.
