Harvesting broccoli at the right time is important to ensure that you get the best possible flavor and nutritional value from your crop. Broccoli that is harvested too early will be tough and bitter, while broccoli that is harvested too late will be woody and less flavorful.
The ideal time to harvest broccoli is when the heads are 6-8 inches in diameter and the florets are tightly closed. The heads should be deep green in color and free of any yellowing or browning. If you wait too long to harvest broccoli, the florets will start to open up and the head will become loose and less flavorful.
