Sowing and planting cauliflower

Cauliflower comes in different forms and requires different growing conditions and times.

Cauliflower sowing:

Growing cauliflower is much slower since it takes almost 7 months between sowing and harvest.

  • Sow in the month of March April under cover for an autumn harvest
  • You can also start sowing in February, in a warm place.
  • Sow in May to July directly in the ground for a harvest in winter if the cabbages are protected from November

Plantation of cauliflower purchased in a cup:

The ideal planting time is just after the last frosts, around mid-May, until September for a harvest in November.

  • Plant the cauliflowers in good garden soil, ideally enriched with nitrogen manure
  • Space each plant 60 to 80 cm in all directions

Caring for cauliflower

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.

  • Transplanting is done every 40 cm.
    This spacing is necessary to give the plants room to develop.
  • Transplant in a well plowed ground.

Watering cauliflower:

Cauliflower is water hungry and should be watered, especially in drought conditions.

  • Water regularly but moderately to maintain good humidity.
  • Avoid watering the foliage to avoid fungus
  • Good mulching helps maintain moisture in the soil
  • Good hoeing allows you to limit the number of waterings ...

Cauliflower disease

One of the main enemies of cauliflower remains mildew. Moisture is the main cause of the development of late blight.

  • Avoid watering the foliage of your cauliflower
  • Do not tighten the plants too much to ventilate the foliage as much as possible
  • Find our advice for fight against mildew

Note also that it is sensitive to attacks from cabbage worms, this caterpillar which creates holes in the cabbage.

Note also that cauliflower can be the target of aphids and, of course caterpillars.

For these 2 pests, avoid at all costs chemical treatments that may contaminate your vegetables and the soil in which they grow.

Cauliflower harvest

When and how to harvest cauliflower, when is the best time:

Harvesting of cauliflower takes place almost throughout the year depending on the sowing periods.

Harvesting takes place about 3 months after planting but this may vary depending on climatic conditions.
