  • Propagation:

    How is broccoli propagated?

    Grown from seed, broccoli will germinate and grow in temperatures as low as 40 degrees F.

    Broccoli needs full sun, and moisture-retentive soil that is well fertilized and slightly acidic ( 6.0-7.0 pH).

    Broccoli must be mulched to keep the soil moist, cool, and free of weeds.

     

  • Harvest:

    How is broccoli harvested?

    When mature, a head of broccoli is 3 to 6 inches in diameter and dark green with lots of tight green buds. Any yellowing indicates it is past its prime.

    Broccoli is harvested in the morning while the soil is still cool from the previous night.

    In a home garden, 9 to 10 inches of the stalk is left in the ground to grow bite-size side shoots, which are great for eating and freezing. One plant may be harvested for several weeks as it puts out these shoots.

    Commercial growers use a harvester to pick their crops.
