Broccoli
Brassica oleracea var. italica
A head of broccoli is a cluster of flower buds. When the head is young its individual buds are packed very tightly. As long as the buds stay tight, let the head grow. Once the head begins to loosen and spread out, they are about to bloom and the head should be cut immediately, regardless or the size.
Once the main head has been cut, many smaller heads, called side shoots, will form on other parts of the plants. They may not be large, but the number of shoots often makes up for the decreased size.

Climate
Broccoli can be grown anywhere except in the hottest and coldest climates, but does require cool weather to reach maturity. Ideal temperatures are not more than 77 degrees during the day and not less than 60 degrees at night. -
Location
Plant in a well drained, sunny location. Broccoli can be planted in containers outdoors. -
Cultivation
Soil should be of a pH between 6.5 and 7.5. Prepare the bed with manures and compost and provide extra nitrogen supplement if the soil is sandy. -
Planting
Sow seeds ½ inch deep. After thinning, plants should be about 10 inches apart. Successive sowings should occur at one month intervals. If starting seeds indoors, use 4 inch peat pots and transplant when 4 true leaves have appeared (6-8 weeks after planting.) -
Watering
The plant grows quickly, so keep soil moist by frequent watering, if necessary. It requires less water as heads begin to mature. -
Fertilizing
Manure, especially poultry manure, is an excellent fertilizer for broccoli. Weekly feedings with liquid seaweed fertilizer also improves crops. -
