How To Grow Cauliflower From A Cauliflower

You can grow cauliflower from a cauliflower, but not in the way you might think.
 
A cauliflower doesn’t grow another cauliflower from its head the way a potato grows new potatoes from its eyes.
 
Instead, you grow cauliflower from a cauliflower by saving and planting its seeds.
 
The catch is that the cauliflower you buy at the grocery store is usually harvested before it produces seeds.
 
So to grow cauliflower from a cauliflower, you need to start with a cauliflower plant that’s been allowed to flower and go to seed.
 
If you’ve ever wondered how to grow cauliflower from a cauliflower, the answer lies in understanding the plant’s full life cycle.
 
In this post, we’ll walk through exactly how to grow cauliflower from a cauliflower, from saving seeds to harvesting your own crop.
 
Let’s dig in.
 

How to Grow Cauliflower From a Cauliflower

To grow cauliflower from a cauliflower, you need to let a cauliflower plant complete its life cycle and produce seeds.
 
Here’s how that works:
 

1. Cauliflower Is a Biennial Plant

Cauliflower is a biennial, which means it takes two growing seasons to complete its life cycle.
 
In the first year, it grows leaves and forms the white head we eat.
 
In the second year, that same plant sends up a tall stalk with yellow flowers.
 
Those flowers eventually turn into seed pods.
 
So to grow cauliflower from a cauliflower, you have to let the plant overwinter and flower in its second year.
 
That’s when the seeds form, and those seeds are what you’ll plant to grow new cauliflower.
 

2. The Head You Eat Isn’t a Seed Source

The cauliflower head sitting in your fridge won’t give you seeds.
 
That tight white curd is actually a cluster of undeveloped flower buds.
 
It was harvested before those buds could open and produce seeds.
 
So you can’t grow cauliflower from a cauliflower head you bought at the store.
 
You can only grow cauliflower from a cauliflower that’s been left in the ground to bolt and set seed.
 

3. Saving Seeds From a Flowering Cauliflower

If you’ve let a cauliflower plant flower, you’ll see small yellow blossoms appear on tall stalks.
 
After pollination, those flowers turn into slender green seed pods.
 
Let the pods dry on the plant until they turn brown and brittle.
 
Then pick them and crack them open to release the tiny round seeds inside.
 
Spread the seeds on a paper towel and let them dry for another week or two.
 
Store them in a cool, dry place, and they’ll stay viable for about four to five years.
 
That’s the real secret to how to grow cauliflower from a cauliflower.
 

Planting Your Cauliflower Seeds

Once you have your seeds, growing cauliflower from a cauliflower is pretty straightforward.
 
Here’s how to do it right:
 

1. Start Seeds Indoors

Cauliflower needs a long, cool growing season, so start your seeds indoors about six to eight weeks before your last frost date.
 
Plant them a quarter inch deep in seed-starting mix.
 
Keep the soil moist and the temperature around 65 to 70°F.
 
Seeds usually sprout within four to ten days.
 

2. Harden Off and Transplant

Before moving your seedlings outside, harden them off over a week by gradually exposing them to outdoor conditions.
 
Then transplant them into rich, well-drained soil with plenty of compost.
 
Space plants about 18 to 24 inches apart so they have room to grow.
 

3. Keep Them Cool and Watered

Cauliflower hates heat, so aim for consistent moisture and cool weather.
 
Mulch around the plants to keep the soil temperature down.
 
Water regularly, but don’t let the soil get soggy.
 
If you’re growing cauliflower from a cauliflower in a warm climate, choose a fall planting so the heads mature in cooler weather.
 

Common Mistakes When Growing Cauliflower From a Cauliflower

Growing cauliflower from a cauliflower isn’t hard, but a few missteps can ruin your crop.
 
Here’s what to avoid:
 

1. Trying to Grow From a Store-Bought Head

As mentioned, the head won’t produce seeds, so don’t bother planting it.
 
You’ll just end up with a rotting mess in your soil.
 

2. Letting Plants Get Too Hot

Heat stress causes cauliflower to bolt early or form tiny, bitter heads.
 
Shade cloth or a fall planting can help if your summers are brutal.
 

3. Skipping the Overwintering Step

If you want to save seeds to grow cauliflower from a cauliflower again, you have to let the plant survive winter.
 
In cold climates, mulch heavily or dig up the plant and store it in a cool cellar.
 
That’s the only way to get seeds for next season.
 

So, How to Grow Cauliflower From a Cauliflower?

You grow cauliflower from a cauliflower by letting a cauliflower plant flower and produce seeds, then planting those seeds.
 
The head you eat won’t work, but a second-year cauliflower will give you plenty of seeds to start new plants.
 
Just start seeds indoors, transplant them into cool soil, and keep them watered and mulched.
 
Avoid heat, don’t plant store-bought heads, and let your plants overwinter if you want to save seeds again.
 
With a little patience, you’ll be growing cauliflower from a cauliflower like a pro.
