Broccoli grown in June in full sun. How do I get my broccoli to form a head? Right now they are shoots that have made yellow flowers on some. Do I need to dig up others and put in container inside for cooler temp? Do I need to tie shoots together to form a head? How do I eat these if they already flowered? Should I put other ones that did not flower yet inside container in house to get better results? Do i tie shoots together in future to form heads? Help...Brocolli is tough to grow..
