Can Broccoli Microgreens Regrow?


Broccoli microgreens are young baby broccoli plants, harvested approximately 10 days after germination. They are really strong, little plants, and are very nutritious as well. 

A few microgreens (such as pea microgreens) have shown the ability to regrow after harvest to provide a second cut. However, for the question as to whether broccoli microgreens regrow after being harvested, the short answer is “No”. This is only but a little disadvantage, as there are many perks to growing broccoli microgreens. 

We intend to show you how to maximize your crop yield and get the most out of your broccoli microgreens. Read on for more. 

Broccoli Microgreen Seed Sources & Varieties

The following varieties of microgreens have excellent seed sources:

  • Broccoli
  • Broccoli Spigarello
  • Broccoli Raab (Rapini). 

Equipment You Will Need To Grow Microgreens

S/No. EquipmentApplication 
1.35% Food Grade Hydrogen PeroxideThis is used when top spraying seeds in germination or rinsing seeds before germination.
2.Waterproof pH Tester This is used to test the pH level of water.
3.Heat MatUsed during germination for certain microgreens whose growth is heat-dependent.
4.TimerUsed for regulating the lights. We recommend that you adopt an “18 hours on, 6 hours off” policy. 
5.Pressure Sprayer Used to top spray microgreens during germination.
6.Tweezers Used for planting seeds.
7.Water PitcherThis is for bottom watering the microgreens.
8.StrainerThis equipment is used to rinse certain microgreen seeds.
9.Gloves These are to be worn when handling hydrogen peroxide and when working in a sterile growing environment.
10.Safety GlassesThis should be worn while handling the 35% food-grade hydrogen peroxide.
11.SyringeTo be used when balancing the pH level of water.
12.Organic Lemon Juice or Citric AcidThis is used to lower the pH level of water.

Planting Broccoli Microgreens – Seeding Density & Germination Tips

  • The crop cycle usually takes 5 to 9 days from seed to harvest.
  • Avoid sanitizing Broccoli seeds
  • You shouldn’t soak Broccoli seeds

Note: Broccoli microgreen seeding density per 1020 tray is 20 – 40 g (0.70 – 1.40 oz)

Bottom-watering helps to minimize mould problems and boost shelf-life. You should therefore place your 1020 tray with holes inside the 1020 trays without holes. 

Scatter the seeds over a pre-moistened tray making use of several passes to uniformly distribute the seed over the surface of the soil.

As soon as broccoli seeds are scattered uniformly over the ground, the seeds can be misted before the trays are piled up such that the dry broccoli seeds are now moist.

Stack trays 1 to 3 high, with the 1020 tray empty (no holes) and a 15 lbs weight on top for around two to four days.

In two to four days, broccoli microgreens will line up along the tray’s sides. Unstack once the broccoli is 1′′ tall, and top- or bottom-water heavily on the day you open up the plants, and finally, position them under the growing lights.

Growing Broccoli Microgreens in 3 Easy Steps

Watering

Heavily underwater the day you surface from the stacked sprouting/germination stage.

Then bottom-water the broccoli to keep the leaf dry for the remainder of the foliage period.

Putting wet broccoli into a clamshell or plastic bag can really shorten its lifespan.

Air

To avoid mould problems, it is vital to ensure good ventilation and low moisture in your growing space. Allow the microgreens to stay for 2 to 5 days under the sun.

Potential Problems 

  • Rooms with weak ventilation (not enough fans) during the growth stage, hot/humid conditions, or mould as a result of overwatering.
  • You can assume that they have been underwatered if you find that your broccoli, or part of your broccoli, droop and lie flat on the ground.

Solution

Bottom-water, and the broccoli will rise up again within 4 to 6 hours.

Harvest: When (and How) To Harvest Broccoli Microgreens

Mean yield: 140-250g/1020 tray

Harvest Tools

Sharp knife (the microgreens are best harvested while 2-3 inches high). 

Do not water the greens for a minimum of 12 hours before the harvest to ensure that they are dry when harvested. 

Cut and place directly into the package. If greens are damp, they must be dried before packing to boost shelf-life.

Packaging

Clamshells or packets that are as dry as possible should be used for packaging, as this ensures that it will comfortably last for 7 to 9 days with refrigeration. 

You can also remove moisture using absorbent pads.

Broccoli Microgreen Nutritional Composition

Broccoli microgreens have high levels of the cellular detoxifier – sulforaphane, which can help in the prevention of cancer, and rejuvenation of the immune system.

In addition, they are really rich in the following:

  • Vitamin B6
  • Vitamin C
  • Vitamin E
  • Vitamin K
  • Dietary fibre 
  • Phosphorus
  • Magnesium
  • Potassium

Vitamin B6: Helps the body convert food into energy and is vital for a healthy body and the growth and maintenance of a healthy brain.

Vitamin C: Allows all body tissues to grow, develop, and heal.

Vitamin E: A good antioxidant that can minimize free radical damage and delay the cell ageing process.

Vitamins K: A crucial element in the maintenance of bones and the repair of wounds.

Dietary fibre: Cleans and extracts waste from the kidneys and controls the energy intake and recycling of the body.

Magnesium: Increases the productivity of the body and has anti-inflammatory advantages.

Potassium: An increased intake of potassium will decrease the overall risk of death by 20% by reducing stroke risk, decreasing blood pressure, and defending against musculoskeletal mass loss.

Tips For Growing Broccoli Microgreens

  • Microgreens are quick to grow and harvest with good yields.
  • Dampen the soil, scatter the seed, and mist before stacking. The misting method increases germination considerably.
  • Bottom-water to eliminate the risk of mold and a rotting smell.
  • It is necessary not to water 12 hours before harvest. If moistened just before processing, it is very difficult to dry the leaves. Wet packaging will shorten shelf life fast!
  • You’ll often find a smaller sized kit at a higher price. They produce high sulforaphane levels that can help reduce heart failure and cancer!

I trust that the tips above will help you improve your yields!

Misting the seeds before stacking and germination has had the largest effect on enhancing our 1020 tray yields.

Frequently Asked Questions

Microgreen broccoli vs full-grown broccoli? Which is more nutritious? 

The following reasons are why microgreens (including broccoli) are typically considered to be more nutritious than full-grown vegetables:

There is no nutrient loss since there is no damping or boiling involved in microgreen products.

Microgreens are tiny, immature varieties of vegetables, herbs, and other plants harvested from between one to two weeks after germination. They are usually more nutritious since they are only harvested one to two weeks after germination. 

Radish microgreens, for example, are considered 40 times more nutritious than mature ones. 

Time is a nutritional adversary for any fresh vegetable, and since microgreens are normally eaten earlier than broccoli heads, they provide more nutritional value.

Which is more nutritious? Broccoli sprouts or microgreens?

Both broccoli sprouts and microgreens are known to have exceptionally high nutritional value. Broccoli sprouts, however, have a slight edge because they are consumed in the growth phase, and a greater effect would be achieved per volume.

How do broccoli microgreens taste?

They have a slightly bitter, crunchy, and ends flavour. I really think it is much better to eat raw microgreens than to eat broccoli!

How do I cultivate broccoli without soil?

All you have to do is follow precisely the same methods as mentioned above to grow without soil. Also, Hamama Microgreens makes a perfect soil pack.
