A lot of home gardeners claim that you can regrow Brussels sprouts from cuttings at home. While there’s not a lot of evidence out there to support these claims, you can still give this experiment a try on your own! Since Brussels sprouts are typically an autumn crop, you’ll have more luck if you hit the ground running in May or June. [1] X Research source
Steps
-
Wash your Brussels sprouts and peel away any dead leaves. Rinse your sprouts over the sink to get rid of any leftover dirt and grime. Then, check the bottom of each sprout and peel away any yellowing or dead leaves. You can use fresh, store-bought Brussels sprouts for this!
- Since Brussels sprouts are harvested in autumn, it’s best to get the ball rolling in May or June. [2] X Research source
- There isn’t a lot of published evidence out there that sprout cuttings will regrow into a full Brussels sprout plant. In some experimental gardening, some amateur gardeners noticed that individual Brussels sprouts can develop a root system on their own. You’re welcome to give it a try! [3] X Research source
-
Cut off the bottom of a Brussels sprout. Slice of the flat, bottom portion of your Brussels sprout. Your sprout will develop roots from the bottom of this cutting.Advertisement
-
Fill a container with 1 ⁄ 2 in (1.3 cm) of water. Set the container in a prominent place, so you’ll remember to check in on your cuttings. Your sprouts don’t need a lot of water—just enough to help them grow a new root system.
- Some experimental gardeners have grown cuttings in a water bottle. [4] X Research source
-
Arrange your Brussels sprouts in the water. Place the sprouts cutting-side-down on the surface of the water. It’s okay if your Brussels sprouts are touching—just don’t cram too many into a single container. If needed, you can always set up a second container for your Brussels sprouts cuttings.
-
Change the water each day. Drain out the old water from the container, and refill it with another 1 ⁄ 2 in (1.3 cm) of clean water. Each day, check the water and remove any dead leaves floating around.
-
Transplant your Brussels sprouts when they’re 3 in (7.6 cm) tall. Measure your cuttings with a ruler throughout the next couple of weeks. Once your plants hit the 3 in (7.6 cm) marker, you can move and transplant them in your main garden. [5] X Research source
- The 3 in (7.6 cm) rule normally applies to Brussels sprout seedlings. Since there isn’t a lot of evidence on this regrowing method, it’s unknown how quickly your cuttings will grow.

-
Plant your transplants between late June and early July in a sunny area. Search for some open space in your garden that gets plenty of direct sunlight. A little bit of shade won’t hurt your plants, but it’ll slow down the growing process a bit. [6] X Research source Once you’ve planted the transplants, sprinkle them with water to help them adapt to their new home. [7] X Research source
- Brussels sprouts typically grow during the summer months, and are harvested in autumn before the first frost hits.
- Ideally, Brussels sprouts need at least 6 hours of light each day. [8] X Research source
-
Water your newly planted Brussels sprouts cuttings. Sprinkle some water over your cuttings, which will help them adapt to their new outdoor home. You can also pick up a transplant starter solution from your local gardening shop—this is a special fertilizer designed for new transplants in your garden. Grab a phosphorus-rich formula that’s low in both potassium and nitrogen. [9] X Research source
-
Use fertile soil to plant your sprouts. Brussels sprouts need fertile soil that drains well, so they get plenty of water. Test your soil to see if it’s somewhere between 6.0 and 7.5 pH, which is the ideal range for growing Brussels sprouts. [10] X Research source
- Brussels sprouts can survive in soil that’s slightly over 7.5 pH, but they really thrive in the 6.0 to 7.5 range.
- For instance, commercial fertilizers like 10-30-10 and 5-10-5 are high in phosphorus. [11] X Research source
-
Space your transplants 18 to 24 in (46 to 61 cm) apart. Place each transplant in the fertile soil, leaving an ample amount of space between each sprout. Bury the roots completely in the soil, so your sprouts can become big and leafy. [12] X Research source
-
Mulch your plants with clippings or straw to prevent weeds. Layer 3 to 4 in (7.6 to 10.2 cm) of grass clippings and straw around your transplants. Use grass that wasn’t treated with any herbicides, so the chemicals don’t transfer to your new plant. [13] X Research source
- Some types of straw have weeds sprinkled into the mix. Make sure your straw is weed-free, so you aren’t introducing weeds into your garden.
-
Nourish the sprouts with 1 in (2.5 cm) of water each week. Brussels sprouts are thirsty plants, and need to be watered on a regular basis. Sprinkle the soil with a lot of water once a week so the soil stays moist to the touch. [14] X Research source
- If it rains frequently, you don’t need to worry about watering your sprouts.
- For reference, in a 4 by 8 ft (1.2 by 2.4 m) garden, 1 in (2.5 cm) of water equals 0.6 US gal (2.3 L). [15] X Research source
-
Cover the soil with nitrogen-rich fertilizer when your plant is 12 in (30 cm). [16] X Research source As a general rule of thumb, apply 1 cup (150-227 g) for every 30 ft (9.1 m) of space. Sprinkle water over the fertilizer, and wait 4 weeks. Then, apply another round of fertilizer to the soil. [17] X Research source
- Some common nitrogen fertilizers are ammonium sulfate or ammonium nitrate.
-
Harvest the sprouts when the weather is 20 to 30 °F (−7 to −1 °C) outside. Unlike other crops, Brussels sprouts keep growing well into the fall months. Once it’s really cold outside, twist the Brussels sprouts off the stalk once they’re green and 1 to 1 1 ⁄ 2 in (2.5 to 3.8 cm) wide.

QuestionWhat do I do with the yellow flowers?Community AnswerYellow flowers means that your plant has bolted. It will taste slightly bitter but is still edible. You can try regrowing another Brussels sprout.

Tips
- Some gardeners recommend pulling 2-3 leaves off the bottom of the plant each week while it’s growing in, which can speed up the harvest. [20] X Research sourceThanks

Warnings
- Regrowing Brussels sprouts is very experimental, and there’s little-to-no concrete evidence that Brussels sprouts can be regrown from cuttings. If you’d really like to grow this plant at home, you’re better off using seeds.Thanks
