Have you only ever seen the creamy white cauliflowers in the market? That is because the public only buy what they know and what they are used to. However, as a vegetable grower, you really should try growing your own cauliflowers to enjoy tasty purple, green and yellow varieties. Although rich deep soil with a bit of space and a lot of watering is the optimum growing condition for cauliflower, you can grow it all year around.


Sowing Cauliflower

Here are the tips for sowing the cauliflower:

  • Sow the cauliflower from March to May. You can also sow it from January to February under glass to get earlier crops.
  • Sow the seed thinly.
  • Make sure the seeds are ¾ inches deep in the seedbed.
  • Space the final rows 24 inches apart for the larger cultivars and 6 inches apart for mini caulis.
  • Thin the seedlings to ensure a distance of 24 inches for larger cultivars and 6 inches for mini caulis.  
  • Avoid growing too many plants at once. 
  • Sow in cell trays using some good potting compost to get good results.

Growing Cauliflower

Cauliflowers grow well in the fertile soil. Moreover, you can follow these tips to grow the cauliflowers effectively.

  • Apply a bucketful of mulch (well-rotted manure) into the soil before planting.
  • Spread two or three handfuls of Vitax Q4 per square meter/yard, a general fertilizer, to help the plants grow.
  • Tread the soil before planting to make it firm.
  • Water the plants one day before transplanting. It will help the plant establish itself, and grow properly. Otherwise, you may experience the formation of small and deformed heads.  

When transplanting the plants, follow the following process:

  • Make a deep hole to transplant the plant.
  • Make sure the lowest leaves on the plants are at ground level.
  • Fill the hole with water initially. Give it a good soaking.
  • Insert the plant into the hole and fill the hole with soil. Make sure a large area of moist soil holds the plant.
  • Firm the soil around the roots well.  

Here’re some other tips for transplanting your cauliflower plants:

  • Make sure the autumn and summer cultivars are 2 ft apart. Conversely, space the winter cultivars around 2.5 ft apart.
  • Water every ten days in dry weather. While watering, pour enough water into the root zone of the plants. They need a good soaking, not a light sprinkling.
  • Add high nitrogen fertilizer (1oz per square meter) when plants start growing. Sulphates of ammonia are the best nitrogen fertilizer that boosts curd formation and overall growth.

Harvesting Cauliflower

Based on the time when you sow, you can harvest the cauliflowers all year-round. Therefore, check the seed packet to see all the instructions.

Generally, it takes 3-5 months for plants to get mature. However, the growth rate may vary according to the cultivar and weather conditions.

Harvest the plants as soon as the head becomes compact and firm. However, if you delay the harvesting until the heads start separating, the taste of the cauliflower will become bitter. Likewise, harvest the white varieties before they turn yellow.

You can use the knife to cut the stem. You can cut a few leaves along with the head.

Common problems


Caterpillars, especially the white cabbage butterfly, eat brassicas. These holes even invade up to the cabbage heart. They make holes in the leaves. So, you will see either holes or caterpillars on the broccoli crop.


  • Pick the caterpillars with your hand in the mild attack.
  • Fine netting (with 5-7mm mesh size) and insect-proof mesh help prevent egg-lying.


Birds, especially pigeons, can cause damage to the crop. They can eat seedlings, fruit, buds, leaves, and vegetables.  


  • Cover the plants with fleece or net.
  • Bird-scaring or scarecrows could also help.


The plants with clubroot show the following symptoms:

  • Roots become distorted and swollen
  • Leaves become pale yellow

Even the death of the plant may also occur with this disease.


  • Add lime to the soil. Lime will make the soil alkaline.
  • Improve drainage
  • Grow the plants in pots
  • Avoid growing the plant in affected soil.
