Start indoors right around the last frost date or later in spring for summer harvest in 2 to 3 months. Seeds will germinate in 7-10 days. Optimal temperature for germination: 10-30°C (50-85°F).

For fall harvest: Start indoors late spring and transplant in July, harvesting just before the first frost date.

For overwintering sprouting broccoli (in mild winter areas): Start indoors late March to mid-April, and harvest the following February to May.

Ideal pH: 6.0-6.8

Broccoli is a moderate to heavy feeder that does best in humus-rich soil amended with composted manure. Set transplants out by the time they have 6-8 true leaves. Mix ¼-½ cup complete organic fertilizer into the soil under each transplant. When plants are 20-25cm (8-10″) tall, push soil around the stems up to the first big leaf to encourage side shoots. Broccoli does best in cool weather.

Cut the crown portion of the broccoli with 5 to 6 inches of stem, after it’s fully developed, but before it begins to loosen and separate and the individual flowers start to develop into bright yellow blooms. Removing the central head stimulates regrowth to develop for later pickings. Cutting the head lower on the stem will encourage fewer, but larger side-shoots. The regrowth portion grows from the base of the lower leaves. You can usually continue to harvest broccoli for several weeks.
