I bought broccoli transplants (Pac Man) from Pike's nursery. I planted them on Sept 1. I havested my first 8 broccoli heads on Oct 28. The next 4 heads were harvested on Nov 3, an additional 4 heads on Nov 10. I have 3 heads remaining. I did use shade cloth for a few weeks while we still had high temps and covered them in Tulle to keep out the pests.

I also experimented with planting broccoli and Kholarbi seeds directly in the garden this year. I planted 4 seeds each week. The first ones were planted on Aug 4, 4 more on Aug 11, 4 more on Aug 18, and the final four on Aug 25. None of the broccoli planted from seed outside has formed heads yet. All of the broccoli is now the same size so planting Aug 1 in the heat did not help getting broccoli any earlier. I guess I should have listened to everybody and started my seeds indoors and transplanted them on Sept 1.

Cabbage - I bought "45 day" cabbage transplants from a big box store and planted them on Sept 1. They are all forming heads but they are small, I guess because of the variety.
