Cauliflower probably requires more exact growing conditions than any other home garden vegetable.  Cauliflower requires cool but frost-free temperatures and a humid climate to develop center heads or curds.  Cold temperatures can cause stunting and premature heading.  Varieties differ in plant size, curd size, and in days to maturity, ranging from 70 to 100 days. 

Cauliflower does best as a fall crop in most areas of Alabama.  Space plants about 18 inches apart in rows 30 to 36 inches apart. 

Exposure to sunlight discolors the head and produces off flavors.  To prevent this, gather the long leaves over the head and tie them together.  This must be done as soon as the curd begins to develop. 

The center head or curd matures about 2 weeks after tying.  Mature curds are about 6 inches in diameter.  Heads turn from clear white at the peak of maturity to yellowish brown when overly mature.  Cool immediately after harvest and keep refrigerated.  If cauliflower must be stored for several weeks before using, leave a portion of the stalk and leaves to protect the curd.
