Step 1 – Gather Your Cauliflower Scraps

How to Grow Cauliflower from Scraps

First things first – collect those leftover cauliflower bits!

  • I like to save my scraps in the fridge until I’m ready to regrow them.
  • Make sure you’ve got the stalk, leaves, and root nodule attached. Those are the key bits that will resprout new growth.
  • Pro Tip: To extend their shelf life, wrap the ends of the stalk in a damp paper towel secured with a rubber band.

Step 2 – Cut the Stalks and Leaves

Once you’ve gathered your scraps, it’s time to prep them for propagating.

  • For the stalks: Trim off any remaining florets. Slice the thick stalks lengthwise into smaller sections about 3-4 inches long. I aim for around 5-6 chunks.
  • For the leaves: Carefully cut off each leaf about 1 inch below where it meets the stalk. Keep the roots intact.

Top tip: Make clean cuts with a sharp knife or pruners to prevent crushing or bruising. I’ve found this helps maximize the chances of regrowth.

Alright, now your cauliflower bits are prepped and ready to grow into new plants! Get your containers ready and let’s move on to rooting them…

Step 3 – Root the Stalks and Leaves

Now the fun begins – rooting your cauliflower scraps! This stimulates new growth so they resprout into full-size plants.

For stalk cuttings:

  • Place them in jars of water, cut sides down. Top off with fresh water every 2 days.
  • In about 1-2 weeks, you’ll see little white roots emerging from the bottom and nodes.

For leaves:

  • Plant each leaf cutting in a starter tray with seedling mix.
  • Water gently and keep moist. Roots will sprout from the bottom within 7-10 days.
  • Optional: Dip the cut ends in rooting hormone powder/gel to encourage faster root growth.

Once your stalks and leaves have a network of roots, it’s time to pot them up!

Step 4 – Pot Up the Rooted Cuttings

Now we’re getting to the fun part – planting!

  • For stalks: Gently remove from water and plant in small starter pots, burying 2/3 of the stalk in soil.
  • For leaves: Carefully transplant each rooted leaf into a 3-4 inch pot.
  • Use well-draining seed starter or potting mix. Firm the soil gently around the roots.
  • Water well after planting to remove any air pockets. Let excess water drain.

Within a few days, you’ll start seeing new leaves sprouting from the stalks and leaf nodes. Your cauliflower scraps are on their way to becoming full-fledged plants!

Step 5 – Grow on the Young Cauliflower Plants

Your stalks and leaves will start rapidly growing in their pots now that they have an established root system.

  • Keep the plants in a sunny indoor spot or greenhouse. Rotate the pots occasionally for even growth.
  • Water whenever the top 1-2 inches of soil are dry. Don’t let them sit in soggy soil.
  • Once roots fill out the starter pots, transplant into larger 4-6 inch containers.
  • Use a diluted organic plant food to feed your regrown cauliflower every 2-3 weeks.

Step 6 – Harden Off Plants

In 6-8 weeks, your regrown cauliflower should be nice-sized young plants ready for the vegetable garden!

But first, you need to harden them off to transition from indoor conditions to outdoor growing. Here’s how:

  • Start setting the pots outdoors for just 1-2 hours daily, bringing them back inside at night.
  • Slowly increase the time outside over 7-10 days, monitoring for any stress.
  • After a week or two, the plants will be acclimated and ready for the garden!

Hardening off prevents shock and gives them the best chance at thriving. It’s a simple but important step.

Step 7 – Transplant to the Garden

Now the fun part – moving your homegrown cauliflower into the vegetable plot!

A few tips for transplanting success:

  • Pick a spot with full sun – cauliflower needs at least 6 hours of direct sunlight.
  • Space plants 18-24 inches apart in rows or beds.
  • Dig holes the same depth as the pot and gently loosen roots before placing in the ground.

Your scrap-grown cauliflower is going to thrive with a little TLC! Let’s get these beauties growing…

Step 8 – Caring for Cauliflower Plants

Now that your homegrown cauliflower plants are settled into their garden spot, they need consistent care and feeding to grow hearty heads.

Here are my top tips for care:

  • Water plants regularly with 1-2 inches per week, avoiding any drought stress.
  • Fertilize every 3-4 weeks with a balanced organic fertilizer to fuel growth.
  • Install stakes on larger plants if needed to prevent toppling.
  • Mulch around the base of plants to retain moisture and prevent weeds.
  • Be diligent about checking for cabbage worms and other pests. Remove by hand if found.

With proper care, your cauliflower will thrive and mature in no time!

Step 9 – Harvesting Cauliflower Heads

In about 8-12 weeks after transplanting, your cauliflower will be ready for picking! Here’s how to harvest:

  • Check for heads forming and swelling, usually 6 inches or larger in diameter.
  • Use a sharp knife to carefully cut the main head off the stem, leaving outer leaves intact.
  • Cut the stem 1 inch below the base of the head to retain leaves for continued growth.
  • Harvest side shoots every 7-10 days for multiple harvests per plant.
  • Store heads in the fridge in a loose or perforated plastic bag for 5-7 days max.

Now you can enjoy the fruits (or veggies!) of your labor – fresh cauliflower grown completely from scraps. How cool is that?

Step 10 – Repeat the Process!

Once you get the hang of it, you can keep the cycle going by re-rooting and regrowing new cauliflower plants from scraps after each harvest. It’s an endless bounty of homegrown goodness!
