If you are growing cauliflower in your garden, it is good to know how long it takes to grow and the growth stages it goes through.
Total Growing Time
The time it takes to grow cauliflower from seed depends on the variety selected. Cauliflower can take 70 to 120 days to grow from seed to harvest. When purchasing seeds, consider the length of the growing season in your area and then pick a variety that will be ready for harvest within that time.
Plants started indoors and transplanted into your garden will be ready for harvest in 55 to 80 days, depending on the variety.
Cauliflower seeds typically germinate in 8 to 10 days. The seeds can be planted directly outside or indoors and then transplanted to their permanent location after germination. The germination period starts at sowing and ends at the emergence of the first set of true leaves.
