  • How to Sow and Plant

    Broccoli may be direct sown or started indoors early for fall and spring crops, or purchased as transplants for a fall crop.

    Sowing Seed Indoors:

    • Start seeds indoors about 8 weeks before outdoor planting.
    • Sow seeds ¼ inches deep in seed-starting formula
    • Keep the soil moist at 70 degrees F
    • Seedlings emerge in 10-21 days
    • As soon as seedlings emerge, provide plenty of light on a sunny windowsill or grow seedlings 3-4 inches beneath fluorescent plant lights turned on 16 hours per day, off for 8 hours at night. Raise the lights as the plants grow taller. Incandescent bulbs will not work for this process because they will get too hot. Most plants require a dark period to grow, do not leave lights on for 24 hours.
    • Seedlings do not need much fertilizer, feed when they are 3-4 weeks old using a starter solution (half strength of a complete indoor houseplant food) according to manufacturer’s directions.
    • If you are growing in small cells, you may need to transplant the seedlings to 3 or 4 inch pots when seedlings have at least 3 pairs of leaves before transplanting to the garden so they have enough room to develop strong roots.
    • Before planting in the garden, seedling plants need to be “hardened off”. Accustom young plants to outdoor conditions by moving them to a sheltered place outside for a week. Be sure to protect them from wind and hot sun at first. If frost threatens at night, cover or bring containers indoors, then take them out again in the morning. This hardening off process toughens the plant’s cell structure and reduces transplant shock and scalding.

    Sowing Directly in the Garden:

    • Sow in average soil in a sunny location in early spring or in midsummer for a fall crop.
    • In rows 2 feet apart, sow seeds thinly and cover with ¼ inch of fine soil.
    • Keep evenly moist. Water gently.
    • Seedlings emerge in 10-21 days.
    • Thin to stand about 16 inches apart when seedlings are 1-2 inches high.

    Planting from Transplants in Fall:

    • Select a location in full sun with good rich moist organic soil.
    • Prepare the bed by turning the soil under to a depth of 8 inches. Level with a rake to remove clumps of grass and stones.
    • Dig a hole for each plant large enough to amply accommodate the root ball. Space plants 1-2 feet apart in rows 2 feet apart.
    • Carefully remove the plant from its pot and gently loosen the root ball with your hands to encourage good root development.
    • Place the top of the root ball even with the level of the surrounding soil. Fill with soil to the top of the root ball. Press soil down firmly with your hand.
    • Use the plant tag as a location marker.
    • Thoroughly water and apply a light mulch layer on top of the soil (1-2 inches) to conserve water and reduce weeds.

    How to Grow

    • While small, floating row covers will help to keep pests at bay.
    • Keep weeds under control during the growing season. Weeds compete with plants for water, space and nutrients, so control them by either cultivating often or use a mulch to prevent their seeds from germinating. Avoid disturbing the soil around the plants when weeding.
    • Keep plants well watered during dry periods to promote rapid, uninterrupted growth.
    • Monitor for pests and diseases. Check with your local Cooperative Extension Service for pest controls recommended for your area.

    Harvest and Preserving Tips

    • Pick broccoli when the heads have tight, firm buds. This happens about 50-60 days after transplant.
    • Cut off central head along with 6 inches of stem so broccoli plants will produce smaller heads, which can also then be harvested.
    • Broccoli may be frozen for future use. Cut florets and blanch them. To do this, drop into boiling water for 2 minutes, then plunge into cold water to stop the cooking, drain and store in freezer bags or vacuum bags.
    • Eat the heads raw or cooked.

  • Broccoli, Bonanza Hybrid is rated 4.8125 out of 5 by 16.
    Rated 5 out of 5 by from All Star Broccoli Can't say enough good about this broccoli. I planted four plants and we are overwhelmed with broccoli. The main center head on each is just the beginning. It produces smaller side shoots all summer long. I have made several batches of broccoli soup just to try to keep up with it. Each cluster is tender and flavorful. We love it.

    Rated 5 out of 5 by from Excellent for our spring garden We've grown Bonanza broccoli in the spring for several years, and it is a fantastic producer. Each plant produces a head between 8 and 10 inches across for us, and the flavor and tenderness is outstanding. Each plant also produces a round of secondary large heads, followed by side shoots for several weeks afterwards.

    Rated 5 out of 5 by from My Favorite Broccoli to Date Reliable 95-100% germination in a fantastic broccoli that tastes wonderful fresh and freezes beautifully. I have had success planting this for spring, summer and fall harvest. It didn't bolt on me even during the 100 + degree dog days of summer. This is definitely my favorite variety so far and will be planted instead of or with any other varieties I may try in the future.

    Rated 5 out of 5 by from Great Broccoli! I will try other varieties, but in combination with this one! :-) In a nutshell: - 100% Germination - Easy to grow - Lot of yield (first the big head, later all the side sprouts) - Excellent taste (though the smell is quite ... intense) :-) Will be growing more of them this fall and see how that goes :-D

    Rated 5 out of 5 by from Beautiful seedlings I just planted the seedlings that I started inside in January. Extremely strong and large with large root system. If these don't do the trick, I quit trying the broccoli thing. (yeah, sure, ha ha)

    Rated 5 out of 5 by from Great Broccoli Grew very well even with the 100F temps we got last summer. Produced lots of large heads and many side shoots. Definitely planting again this year. I started indoors in March then transplanted.

    Rated 5 out of 5 by from Great germination Seeds sprout in 10-21 days per the packet. Well we started to see them in 3! What's more. I planted 48 seeds -- 4 each in 12 compartments in a seed starting tray (a Burpee Eco-Friendly Seed Starter 36 Cell Greenhouse Kit, though I give 95% of the credit to the seeds). This was about half the packet -- may try a second crop a bit later. They have been sitting on a counter, not very near a window, with only a regular household lightbulb in a drop light a couple feet over head which is on most of the day. Today, a week after planting, it was finally very warm and not too windy so they spent the day in real sunshine. Meanwhile, under those conditions, in a week's time I have 45 of the the 48 sprouted -- an outstanding percentage -- and most are over a good two inches high already. Meanwhile, a couple are just breaking through today, so in a few more days we might even have the full 48. Fantastic
