What Is It About Leeks—

What Is It About Leeks—

...that supposedly makes them so hard for amateurs to grow?

I'm asking because I want so much to grow them! I love to cook and leeks do figure prominently in many of the dishes I want to prepare, as do shallots (not the same dishes.)
I've read that leeks are exceptionally difficult for plain folks like me, not being a commercial nursery or a farm and not holding a degree in biology or agriculture, to grow.

What is it about them that makes them difficult? I know they like very rich soil and require a long season---er, how long would that be, by the way?---and that they have to have the soil mounded up around them as they grow. But that doesn't sound *hard.* What am I missing? What else do I need to know?
Am I being foolhardy in thinking I can try this and [gasp!]--dare I say it, lol!---succeed?

I'm in zone 5b, by the way.
