What Is The Key To Growing Good Strawberries [POLL]

OK, I give up. I have had strawberries planted for three years and they just aren't producing. Everything else in my garden does well, but my strawberries always struggle. I know that I have to be doing something wrong.

Alot of people in this area are great garderners and have been growing strawberries a lot longer than I have been so I am gathering all gardening tips.
