What is the right time / way to harvest cauliflower?

Question

I only have one plant! It did very well. Your tips on harvesting are appreciated.

Answer 1

The cauliflower head’s curd develops rapidly under proper growing conditions. It grows 6 to 8 inches in diameter and is ready to harvest within 7 to 12 days after blanching begins. The mature heads should be compact, firm and white. Harvest the heads by cutting the main stem. Leave a few green outer leaves attached to protect the heads. Cut the heads before they become overmature and develop a coarse, "ricey" appearance. Once individual florets can be seen, quality deteriorates rapidly. Because cauliflower does not ordinarily develop side shoots, plants may be disposed of or composted after heads are harvested.

When harvesting cauliflower look for a tight evenly shaped head without blemishes. Discoloration is from exposure to the sun. The leaves are generally pulled over the cauliflower "curds" after they are formed and before they ripen, which gives it a nice white, creamy color. If this isn't done they will discolor, but the taste will still be okay. You should cut through the stem with a very sharp knife, just below the head. They are ready when the head is nice uniform shape, but before the florets or the "curds" begin to separate. A quick note on watering the cauliflower plants. Never let them dry out...keep them watered evenly at all times or they will not produce good sized heads, but very small ones instead.
