Step-by-Step Guide

Brussels sprouts aren’t just a side dish for your holiday feast. When properly cared for and nurtured, these crunchy, miniature cabbages are a delicacy.

Here’s a step-by-step guide on how to grow Brussels sprouts in your garden:

  1. Planting: Brussels sprouts require a cool climate to grow, so it’s best to start them indoors 6-8 weeks before the last frost date in your area. Fill seed trays with seed starting mix and sow the seeds about ¼ inch deep. Keep the soil moist and place the trays in a warm location until the seeds germinate. Once they have developed true leaves, transplant them into larger pots.
  2. Transplanting: Brussels sprouts need plenty of space, so when the seedlings have grown to about 6 inches tall, transplant them into your garden. Choose a location with full sun and well-draining soil. Space the plants about 24-36 inches apart and ensure they are at the same level as they were in the pots. Water thoroughly after transplanting.
  3. Soil and Fertilizer: Brussels sprouts thrive in fertile, loamy soil rich in organic matter. Amend the soil with compost or well-rotted manure before planting. Additionally, Brussels sprouts are heavy feeders. Apply a balanced fertilizer every few weeks throughout the growing season to provide them with the necessary nutrients.
  4. Watering: Brussels sprouts need consistent moisture, but be careful not to overwater them. Keep the soil evenly moist, especially during dry spells. Mulching around the plants will help retain moisture and prevent weeds.
  5. Support: As the plants grow taller, they may become top-heavy and prone to bending or falling over. Providing support, such as stakes or a trellis, can help keep the plants upright and prevent damage.
  6. Pest and Disease Control: Brussels sprouts are susceptible to pests like aphids, cabbage worms, and slugs. Monitor your plants regularly and take appropriate measures to control pests, such as using insecticidal soap or picking pests off by hand. Diseases like clubroot and powdery mildew can also affect Brussels sprouts. Practice crop rotation and maintain good air circulation to minimize disease risks.
  7. Harvesting: Brussels sprouts mature in about 90-100 days from transplanting. Harvest the sprouts when they reach a size of about 1-2 inches in diameter. Start picking from the bottom of the stalk, working your way up. Snap the sprouts off the stalk or use a sharp knife to cut them off. Don’t harvest all the sprouts at once; leave the smaller ones to continue growing.
  8. Storage and Cooking: Brussels sprouts can be stored in the refrigerator for up to a week. Remove any outer leaves that may have wilted before storing. To cook them, lightly steam or sauté them until they are tender but still vibrant green. They can also be roasted or used in various recipes like stir-fries, salads, and even as a pizza topping.

With these tips in mind, you can enjoy a productive Brussels sprout harvest right from your own garden!

These green gems offer a wonderfully unique taste experience. The nutty and sweet flavor they bring to your palate is something only a few can resist. Steam or grill them, and you will have a side dish that not only boasts taste but also adds texture and color to your meals.

Planting Brussels Sprouts

When Is the Best Time to Plant Brussels Sprouts?

The best time to plant Brussels sprouts is in the late summer or early fall, as they prefer cool weather. These vegetables have a long growing season, so starting them as soon as possible ensures a successful harvest.

You can also plant them in the spring, but they may not develop as fully as those planted in the fall.

How Far Apart Should I Plant My Brussels Sprouts?

When planting Brussels sprouts, give them enough space to grow. The plants should be spaced about 18 to 24 inches apart in rows that are 24 inches apart. This distance will allow each plant to have enough room for its leaves and sprouts to develop fully.

If the plants are too crowded, they may not grow as well and may have a lower yield.

Should I Mulch Around the Brussels Sprout Plants?

Mulching around the Brussels sprout plants can be beneficial in several ways.

Mulch helps to retain moisture in the soil, reduce weed growth, and regulate soil temperature. It also helps to keep the soil loose and prevents crusting, which can inhibit the growth of young plants.

To mulch around the Brussels sprout plants, spread a layer of organic mulch, such as straw or shredded leaves, around the base of each plant.

Caring for Brussels Sprouts

Do Brussels Sprouts Require a Lot of Water?

Brussels sprouts require consistent moisture, but they do not like to be waterlogged. It’s essential to provide them with about one inch of water per week, either through rainfall or irrigation.

Be sure to water deeply to encourage deep root growth and avoid shallow watering, which can lead to weak plants. Yet, be careful not to overwater, as this can cause root rot and other diseases.

Should I Stake the Brussels Sprout Plants?

Staking Brussels sprout plants is generally not necessary, as they have a sturdy stalk that can support their growth.

That said, if you notice the plants are top-heavy or leaning to one side, you can provide support by using stakes or cages. Doing so will help prevent the plants from falling over and reduce the risk of damage to the stalks.

Can I Use Compost on My Brussels Sprouts?

Using compost on your Brussels sprouts can be highly beneficial. Compost is rich in nutrients and organic matter, which can improve the soil structure and provide essential nutrients for plant growth.

Before planting, you can enrich the soil with well-rotted compost. During the growing season, you can also apply a layer of compost around the base of each plant to provide a slow-release source of nutrients.

Harvesting Brussels Sprouts

When Is the Right Time to Harvest Brussels Sprouts?

The right time to harvest Brussels sprouts is when they are firm and about an inch in diameter. You can begin harvesting the lower sprouts first, as they tend to mature earlier.

It’s important not to wait too long to harvest, as the sprouts may become loose and lose their flavor. Harvesting can typically begin in mid to late fall, depending on when you planted the seeds or transplanted the seedlings.

How Do I Know if My Brussels Sprouts Are Ready for Harvest?

You can determine if your Brussels sprouts are ready for harvest by gently squeezing the sprouts. If they feel firm and have reached the desired size, they are ready to be picked. The sprouts should have a vibrant green color and tightly packed leaves.

Avoid harvesting the sprouts if they are loose, yellowing, or have opened leaves, as these may not be fully developed.

What Is the Proper Way to Harvest Brussels Sprouts?

To harvest Brussels sprouts, snap or cut off the sprouts from the stalk using a sharp knife or pruners. Start from the bottom of the plant and work your way up, harvesting the mature sprouts as you go.

Remember to leave the top of the plant intact, as it will continue to produce new sprouts for some time.

If any mature sprouts remain on the stalk after the main harvest, you can leave them and continue harvesting as they mature.

Common Problems When Growing Brussels Sprouts

How Do I Deal With Cabbage Worms on My Brussels Sprouts?

Cabbage worms can be a common pest problem when growing Brussels sprouts. To deal with them, you can start by handpicking the worms from the plants and dropping them into a bucket of soapy water. You can also use organic sprays or solutions containing Bacillus thuringiensis (BT), a natural bacteria that explicitly targets caterpillars.

What Should I Do if My Brussels Sprout Plants Are Affected by Frost?

If your Brussels sprout plants are affected by frost, take immediate action to protect them. Frost can damage the leaves and sprouts, causing them to turn black and become inedible.

To prevent frost damage, you can cover the plants with a frost blanket or row cover. You can also provide additional protection by watering the plants before a frost event, as moist soil retains heat better than dry soil.

How Can I Protect My Brussels Sprouts From Pests?

You can take several measures to protect your Brussels sprouts from pests. One effective method is to use row covers or netting to prevent pesky insects from reaching the plants.

Alternatively, you can apply organic insecticides, such as neem oil or insecticidal soap, to control common pests like aphids and cabbage loopers.

Tips for Growing Brussels Sprouts

What Is the Ideal Growing Season for Brussels Sprouts?

Brussels sprouts prefer cool weather and have a long growing season.

The ideal growing season for Brussels sprouts is from late summer to early fall, as they can withstand light frosts. By planting them at this time, you can take advantage of the cooler temperatures and provide the sprouts with the conditions they need to thrive.

Should I Start Brussels Sprouts From Seed or Buy Seedlings?

You can start Brussels sprouts from either seed or seedlings, depending on your preference and the time you have available.

Starting from seed allows you to have more variety options, as there are numerous cultivars to choose from.

Starting from seedlings can save you time and effort, as they are already partially grown.

Whichever method you choose, be sure to provide the young plants with the proper care and attention they need to establish themselves in your garden.

What Are the Recommended Growing Conditions for Brussels Sprouts?

Brussels sprouts grow best in full sun, as they require at least six hours of direct sunlight per day. They prefer rich, well-draining soil that is slightly acidic, with a pH between 6.0 and 6.8.

The soil should also be fertile and high in organic matter. Provide the plants with adequate nutrition by fertilizing them regularly.


Cultivating Brussels sprouts can be a rewarding experience. With its compact design and impressive yield, this nutritious, cool-weather crop makes an excellent addition to any garden canvas.
