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, Sun King Hybrid is rated out of 5 by 12.Rated 5 out of 5 by ocfishguy from ...I got a Crop... I have a new found interest in small space pot planted veggies. I have no idea what I'm doing. But, I'm trying! I planted (6) Sun King Hybrid Broccoli plants in a 24"x24" Pot in Sept 2015. I'll try to post the virgin plants and show my 01JAN2016 pic of the finished fruit too. I planted this Broccoli along with Snow Ball Cauliflower. I'm happy with my results! I'm learning to grow plants from a pot on the Veranda in a small space. Thanks Burpee! Much fun and a learning experience for me!! I'll be back!Date published: 2016-01-01Rated 4 out of 5 by sunflowerlover from Good Heat Resistance! Very good germination- about 17 out of 20- and very nice growth. The plant didn't produce that much but the ones I got tasted very good. The plants are very heat and cold hardy and survived well in unpredictable Southeastern temperatures. One day it would be 60, and the next it would be 90. I would definetely recommed this product. Germination: A- (17 out of 20, 85%) Plant Growth: A Yield: B Overall: A- Sincerely, SunflowerloverDate published: 2015-11-22Rated 2 out of 5 by JessicaB from Good taste but small profit This was a new variety for me to try. I basically wanted to plant broccoli for a fall crop but needed plants not seeds. This was the only broccoli plant burpee offered. Plants arrived and we're beautiful. They grew hearty but took MUCH longer than 71 days for maturity. Normally I would say it's because it was a fall crop but we had a rather mild fall. Om cool nights (anything under 40° i used my crop cover). The heads were small and the side shoots were barley what I would consider a floret. In fact 1 plant produced a main head that was only 2 inches in diameter. That being said...it had an excellent flavor. But if you're looking to produce enough broccoli to store away for the winter this is NOT the variety to use. I will be returning to the Goliath variety and raising seeds cone February for a spring planting.Date published: 2015-11-21Rated 4 out of 5 by FarmerTK from Beat Back The Biters I forget which is which, but I know at least one of the broccoli in the images is Sun King; the other is Pacman. At any rate, yet another Burpee veggie that bests the flavor of store-bought by far. I grew these in Smart Pots and were surprised at the density of the root systems. You definitely have to beware cabbage moths - they appear out of nowhere and can inflict serious damage overnight. Get rid of them once spotted. I seem to have caught mine early - I cut off the damaged leaf and the plant regenerated without succumbing. The likes of Neem oil, pepper spray, etc. are musts to keep the biters at bay. If you succeed at doing that, you'll be rewarded. Not giant heads but sweet, tasty and nutrient-rich just the same.Date published: 2015-10-25Rated 5 out of 5 by Olivia from Great Great Great Grew great, huge tight heads, with more side shoots than the other packman variety that we grew, produced for months. Very happy with this purchase.Date published: 2015-10-14Rated 1 out of 5 by GrandmaBudge from Horrible! No one had Green Goliath seed this year so we tried this variety. luckily it was only 3 of our 12 plants. It is a terrible variety! Maybe it is just not good for our area. It had tiny first heads (about 2" across) that bolted quickly. The side shoots never make heads but bolt straight way. Broccoli is a big deal for us and we usually eat it fresh until Thanksgiving but not these! They are coming out today! Another good one for us is Bonanza - NEXT YEAR.Date published: 2015-06-11Rated 5 out of 5 by theIguana from Plucky little dudes I used these in my Aquaponics experiment. Almost every seed germinated and the young plants have survived nitrogen and potassium deficiencies. Purchased just a couple months ago, and they are my fastest growers.Date published: 2014-11-14Rated 1 out of 5 by BC2014gardener from big disappointment Plants grew well and we protected them from cabbage moths with floating row covers. Was SO disappointed when the heads came up thin, stalky, and turned black within days. Not sure what went wrong.Date published: 2014-09-21
