- Seedling – If you have planted seeds in the pots, you can transplant them to the garden when they are about two inches long. Plant seedlings in rows with about 12 inches between each plant so that they can find a place to spread.
- Leaf growth – As Cauliflower grows, it will produce large leaves, and plants need to be watered regularly during this phase, especially if there is no heavy rainfall.
- Head growth – Once Cauliflower heads start to grow you can collect leaves to cover the head and protect them.
- Harvesting – Cauliflower is ready to harvest 80 to 100 days after planting seeds, depending on different varieties and weather conditions.

In the case of Cauliflower, the bud of the developing flowers is protected from light so that the color is white and the flavor mild.
Why is my Cauliflower spiky?
The culprit is the rise in temperature, which topped 27°C around the time of the formation of the curd. Stress and confused plants try to revert to vegetative growth in the middle of curd formation.
