To check when cauliflower are most likely to thrive in your area, see the USDA Plant Hardiness Zone Map. If you live outside the US, do a quick search for ‘plant hardiness zone + [city]’.

How to Plant Cauliflower the Right Way

There are a number of things to consider that will help you avoid some of the common mistakes of growing cauliflower in your home garden.

Often overlooked, your soil can have a huge impact on how well your cauliflower grow. Generally, your soil should be  rich, moist, well-drained soil. Soil PH levels should be around 6 to 7.

roughly every 3′. roughly 1.5′ apart in rows. The seeds should be sowed at a depth of about  .5″. For each plant, be sure to sow at least a few seeds to ensure that at least one of them will germinate.

Begin thinning your cauliflower seedlings when seedlings are 1″ tall, thin to 1 plant.

How Much Sunlight is Needed to Grow Cauliflower

The amount of sunlight is another key to a successful harvest. Too much sunlight will dry out your cauliflower. Not enough sunlight will stunt your its growth or even kill it.

Ideally, your cauliflower should be getting full sun, which means as much sunlight as you can possibly give it, or at least 6 hours or more.

How Much to Water Cauliflower

As you’ve figured by now, a lot can have an impact on how well your cauliflower do, and the amount of water is no different.

Ideally, the soil should be damp to touch; not soggy or bone dry. If the leaves on your cauliflower begin to change colors or start to look droopy, you need to adjust how much water you’re giving it.

Unfortunately, if you give it too much or too little water, you can kill it, so it’s best to just keep an eye on it and water as needed.

How Long Does it Take Cauliflower to Germinate and Grow?

Now the fun part begins and you get to watch your cauliflower grow.

It takes approximately 10-15 days to germinate, and a total of 65-70 days from seed to harvest.

When to Harvest Cauliflower

Cauliflower can grow up to about 5 to 8 inches (13 to 20 centimeters) in diameter.

What Can Cauliflower Be Used For?

Flavor Profile: Crisp, crunchy, and mild.

Can Cauliflower Grow in Pots and Containers?

Yes, you will ideally need a 12″+ containerfor each plant. This can help control weeds and keep your plant from growing out of control.

It also gives you the flexibility to move your cauliflower around if you need to adjust sunlight or bring it indoors to avoid harsh weather conditions.

Are Cauliflower Safe for Bees?

Yes, cauliflower are safe for bees.

According to, bees pollinate human food crops that make up about 90% of the world’s nutrition.

Given their importance in our ecosystem and food supply, I feel it is important to note that growing cauliflower is bee-friendly.
