Broccoli is one of the best fall vegetables. Broccoli has a central
green head that, when removed, forms smaller lateral heads.
Broccoli is best grown from transplants that can be purchased locally
or grown at home. Broccoli does best in a moderate to highly fertile,
well-drained soil. Space plants about 18 inches apart in rows 36
inches apart. Maintain a fairly rapid growth
rate throughout the season with adequate water and fertilizer.
Approximately 3 to 4 weeks after transplanting, apply a sidedress application
of a small amount of ammonium nitrate to stimulate growth.
Broccoli heads are a mass of flower buds. Harvest the heads before
flowers open and show yellow. When ready to harvest, the central
head usually measures 3 to 6 inches across. Lateral heads that develop
after harvesting the central head are much smaller. When harvesting,
cut 3 to 4 inches of the stem and accompanying leaves with the head.
Use or freeze broccoli soon after harvesting. |
