I planted an artichoke last year and even though it did not produce the first year it was a huge, beautiful plant. I made the mistake of not cutting it back this year as we had a very mild winter and I'm a newbie. So this year I got some artichokes and while the plant is huge (4-5' tall & 5-6' wide) the buds are small the king head was ~3-4" in diameter and the others about 1/3 of that. They were also a little bitter. What am I doing wrong and how can I fix it? I'm really bummed out I love artichokes and was really looking forward to these yummy suckers. Thanks, Kristin
