Broccoli does best when temperatures remain between 40 F and 70 F during the growing period. Temperatures below 25 F can damage or kill broccoli. Spring planting should occur as soon as soil can be worked and after last frost, and fall planting done 10 to 12 weeks before first frost. In most areas broccoli grows best if planted in late summer so it can mature during cool periods. Plants can grow 2 ft tall.
