This is the first time I've ever tried to grow brussel sprouts and I have some questions about them. Most of the plants are doing fine, but one of them appears to be going to seed. Is this a problem? Should I pinch back the flowers or just let it be? Only one plant is flowering so far, and it was a plant that got very heavily hit by flea beetles this spring, but I would love some advice on what I should be doing to insure I get a good crop from these plants. Thanks!
