Once you have cut the head off your broccoli plant instead of pulling out and starting again, leave it in. smaller heads grow out just above where the leaves join the stem. You can keep eat broccoli for months. I did this a few years ago and we eat broccoli at least 2 or 3 times a week for about 4 months off 8 broccoli plants.
