Cabbage, Brussels Sprouts, and Cauliflower Help

[johnc399]

Planted Cabbage, Brussels Sprouts, and Cauliflower April 7th in good Black garden dirt about 10 inches deep in raised bed. I mixed in some garden lime and 10/10/10 fertilizer. PH is now 7.

Plants grew large but produced no heads. What did I do wrong?

Potatoes, peas, beans, zucchini, tomatoes and everything else did well.

Where do you live? Please update your profile as to location and hardiness zone. Alaska to Florida and every where in between have different growing habits.

Sounds like too close together.
Brassicas need room.

And cool weather. And don't spit tobacco juice on them.
