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 4.4 out of 5 by 23.
Rated 5 out of 5 by from prolific, cut and come again This is the first year I've tried this particular variety, and I have to say it's likely to be the last variety I ever plant. Typically I'll plant broccoli in the spring and again in the fall so that I can harvest enough to put by for winter. This year I admit I was slacking a bit and didn't start a second crop. After I harvested the main heads, I was rewarded with multiple side shoots all summer long. It's mid-September and I'm continuing to harvest them at a steady rate. None of my plants have bolted despite several sweltering days.

Rated 2 out of 5 by from Didn't Grow This Year After being impressed with this variety last year I attempted to grow it again this year. I started with 72 seeds indoors but only 9 came up. When I transplanted them outdoors I planted the remaining 300+ seeds directly in the ground and only 3 came up! 3!! Admittedly the 12 plants were productive with great flavor but talk about terrible germination.

Rated 1 out of 5 by from No Luck Planted according to instructions, proper soil prep, watering - and less than 1 % of the seeds germinated Very disappointing...

Rated 5 out of 5 by from Wonderful broccoli Not huge heads, but prolific side shoots! Will grow again.

Rated 2 out of 5 by from Most seed didn't germinate Read a few good reviews so thought I'd try them. I only got about 25% germination. Overall very disappointed!

Rated 5 out of 5 by from Best Ever! I am totally new to gardening and things have been going well with almost all of my burpee's products. This is the best broccoli we have ever eaten...I mean ever. My family is pretty picky and they agree, best ever. I will never buy another broccoli seed.

Rated 5 out of 5 by from Produced broccoli for 6 months! In Cincinnnati, I started 8 seeds, yielded 8 plants, in late March 2015, transplanted outside in May, on west side of my garden so they would get afternoon shade, picked the main head in July, picked side shoots all summer and fall, almost daily, up until the first hard, sub 20 F. frost after Christmas. Produced for 6 months!

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.
