Overview:
Cauliflower, like broccoli, is a member of the cabbage family. It is very
similar to broccoli in texture, taste and look. It became a delicacy in France
in the 16th century. Cabbage can be grown in a variety of colors; white
being the most common. Out of all the cabbage family plants, cauliflower is
the most temperamental and difficult to grow. It is not a recommended
vegetable for new gardeners to grow; rather, it may be best to start with an
easier member of the cabbage family.
Planting and Growing:
Cauliflower should be sown indoors 4 weeks before the last frost date.
Before transplanting the seedlings outdoors they should be hardened off.
Harden off cauliflower over a 3-day period by setting them outside and
slowly introducing them to full sun. Transplant the seedlings when two sets
of true leaves appear. Bury the plant to the base of the first set of true
leaves, being careful not to disturb the roots when transplanting.
Cauliflower can also be directly sowed in the garden around the last frost
date; however, this will produce a later crop than those shown early
indoors.
Like cabbage and broccoli, cauliflower is a heavy feeder. Amend the soil in
the fall with nutrient rich compost. After planting, spread an organic
fertilizer with high levels of nitrogen, potassium and phosphorous. Repeat
fertilizing every four weeks until harvest.
Water cauliflower moderately so the soil is consistently moist, but not
saturated. Soil temperatures should also remain cool, no more than 75
degrees F (24 degrees C). To maintain consistent moisture and temperature
levels, spread 3 inches (7.5 cm) of organic mulch around the plant. As the
plant reaches maturity, watering levels will need to increase to keep up with
the growth and leaf expiration.
Harvesting and Preserving:
When the head is about 2-3" (5-7.5 cm), blanch the cauliflower to improve
the color and texture. Blanching is accomplished by folding a few large
leaves over the top of the cauliflower head, and tying them together with
twine. This cuts off sunlight to the head, allowing them to harden off. It is
important to check the head often for maturity. Maturity should occur
between four and ten days after blanching. Don't wait longer than this or
the head may rot. You will know it's mature when the head is tight and
even.
Blanching is not required with some varieties that produce leaves that cover
the head. Simply, leave these plants until the head is mature and ready to
harvest.
After harvesting the cauliflower head, it should be eaten soon. Cauliflower
does not store well, but can last in the root cellar or refrigerator for a
month or so.
