Broccoli, Sun King Hybrid

Short Description

Tight blue-green heads stand up against the heat of summer.

Full Description

Attractive blue-green heads sit ready to harvest through the heat and sweeten more when kissed by fall frosts. Well leafed plants yield these 6-8" diameter heads and 5-10 1" side shoots as well. GARDEN HINTS: For earlier harvest, sow seeds indoors in a sunny spot or under plant lights 6 to 8 weeks before outdoor planting date- this works for both the spring and fall! If purchasing plants in the fall, plant upon arrival and harvest before heavy frost hits. Avoid planting in garden area where cabbage family was grown the year before. Withstands light frost.

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.

Rated 5 out of 5 by from Was Wonderful! These plants were part of my very first FALL garden. Were very hardy, and was pleased with their 10-12 inch heads, and then all the little heads that popped up later. Had great taste, and seem to be freezing well for winter dinners.

Rated 4 out of 5 by from Good producer with second heads Planted 6 seedlings. All did very well, and continued to produce generous side heads after cutting the main head. This in spite of a very warm and dry June.

Rated 1 out of 5 by from Disappointing I planted the broccoli as soon as I got it. It was planted in grow boxes. Although the plants leafed out well, there is still no broccoli. Very disappointing.

Rated 5 out of 5 by from Ordering vs local purchase My parents ordered from seeds from Burpee for years. It was always fun to look through the catalog with them and choose the seeds. I am now growing a few things in raised beds. This year I decided to try Burpee for old times sake. I ordered strawberry plants and seeds. I am amazed. The plants are healthier than any I have purchased locally and the seeds are 100% dependable with exceptional results. I am a Burpee cheerleader now!

Rated 1 out of 5 by from Never sprouted First time buyer of these seeds. Planted in raised beds that last year had okra, which grew great. But after 3 weeks of automatic watering, these seeds have not even broken the surface of my beds. I use organic fertilizer ( cow manure ) but the seed bombs!

Rated 5 out of 5 by from Dependable vegetable plants Received my Sun King broccoli plants, and as usual for Burpee plants, they are lush & healthy, in marvelous condition due to outstanding packing for shipping. Past experience tells me they will be very productive, as long as the green cabbage worms don't overwhelm me!!!

Rated 4 out of 5 by from Sun King - Grocery Store Quality Heads, Good Taste I started Sun King from seed this year, along with Di Cicco and Calabrese. I grew them in average Ohio soil supplemented with alpaca, horse and chicken manure and using a woven weed barrier. The weed barrier also served to keep the soil moist even during dry periods. Occasional watering was required. I'm pleased with Sun King. The heads look similar to what you'd expect from grocery store broccoli, although just a bit smaller than average. The first head I picked two days ago weighed half a pound and side shoots were coming out as well. The taste is outstanding. Planted indoors Feb. 28. Transplanted outdoors April 22. First harvest June 19. Days from seed to harvest: 111 Days from transplant to harvest: 58
