Growing, sowing, planting and harvesting, this is how to have beautiful broccoli.

Sowing and planting broccoli

The best way to grow broccoli cabbage is by sowing it, in soil previously enriched with compost, manure or an amendment such as manure and algae.

This fertilization must take place several weeks before sowing.

Broccoli seedlings:

Before sowing, you must turn the soil deeply to loosen it well.

  • The first broccoli sprouts, says early, can be sown from March, under shelter, for a harvest from August to September.
  • For a sowing directly in the ground we will wait until the end of all risk of frost, may or june.
  • Broadcast sow then lightly bury the seeds.
  • Tamp lightly then sprinkle in a fine rain.
  • Thin to 10 cm when the broccoli has formed a few leaves

Planting broccoli bought in pots:

If you don't have time to sow your broccoli, opt to buy already formed seedlings.

If you have sown under cover, transplant the broccoli in the ground.

The first broccoli plants appear for purchase in late spring but it is from mid-May that we can put them in the ground outside.

  • The ideal time to plant is the beginning of summer.
  • Respect a distance of about 60 cm in all directions between each plant.

Caring for broccoli

As soon as the plants have minimum 3 to 4 sheets, transplant directly in place while protecting your crop if this is to be done before May.

  • The broccoli is transplanted every 40 cm.
    This spacing is necessary to give the plants room to develop.
  • Transplant in a well plowed ground.
  • Water your broccoli regularly but moderately in fine rain to maintain good humidity.

Watering the broccoli:

To thrive, broccoli needs regular watering to keep the soil moist.

  • Water without over-wetting the foliage to avoid fungi
  • Mulch the stems of your broccoli cabbages to maintain moisture in the soil
  • Hoe regularly to facilitate the passage of water through the soil and prevent weeds

Broccoli in winter

Broccoli cabbage is resistant to cold and frost and should be protected during winter.

If your climate is mild in winter, you can leave them in the ground, with a light protection such as a small plastic tunnel.

If, on the other hand, you are subject to severe frost in winter, you have to remove the broccoli with its root ball and replant it under cover.

At the end of winter, you can put them back in the ground
