Brussels Sprouts: The Complete Guide | How To Grow, Plant, & Harvest

Brussels sprouts are a type of vegetable belonging to the Brassicaceae family, which includes other vegetables like cabbage, broccoli, and kale. They are small, green, leafy buds that resemble miniature cabbages. Brussels sprouts grow on a tall stalk and are typically harvested when they are 1 to 1.5 inches in diameter.

Brussels sprouts have a slightly bitter taste and a firm texture. They are often roasted, sautéed, boiled, or steamed as a side dish and can be flavored with various seasonings and ingredients like bacon, garlic, or balsamic vinegar to enhance their flavor. They are known for their nutritional value, being rich in vitamins, minerals, and dietary fiber.

Brussels sprouts are a popular vegetable in many cuisines and are often served during the fall and winter months as they are a cold-weather crop. They can be an acquired taste for some due to their distinctive flavor, but they are enjoyed by many when prepared properly.

Can you plant Brussel Sprouts in a Container?

Growing Brussel sprouts in containers and grow bags is a great way to enjoy this nutritious vegetable. When growing Brussel sprouts in containers and grow bags make sure to select a large and deep pot to accommodate the extensive root system of the plant. Grow bags are an excellent choice and will help keep you from over watering. Remember, when growing Brussel sprouts in a container you need to keep the soil consistently moist.

What is the best way to plant Brussels sprouts?

To plant Brussels sprouts successfully, start by choosing the right time and location. Brussels sprouts thrive in cool temperatures and are typically planted in late summer or early fall for a winter or early spring harvest. 

Select a sunny spot with well-drained, fertile soil. You can start Brussels sprout seeds indoors or directly sow them in the garden, depending on your climate and preference. When transplanting, space the seedlings about 18-24 inches apart in rows, leaving 2-3 feet between rows for good air circulation. 

Maintain consistent soil moisture without overwatering and mulch to help retain moisture and suppress weeds. Provide support for the plants as they grow, as Brussels sprouts can become top-heavy. Be vigilant for pests and diseases, using natural or organic control methods as needed. 

Harvest the sprouts when they reach a firm, bright green and about 1-1.5 inches in diameter, starting from the bottom of the stalk and working your way up. Specific instructions may vary by climate and variety, so always consult local gardening guidelines or seed packets for the most accurate advice.

Best outdoor temperature for growing Brussels sprouts?

Brussels sprouts thrive in cool weather and are considered a cold-weather crop. The ideal outdoor temperature for growing Brussels sprouts ranges from 45°F to 75°F. They can tolerate a light frost and even benefit from it as it can improve their flavor and make them sweeter.

How much light do Brussels sprouts need to grow?

Brussels sprouts require a substantial amount of light to grow and develop properly. They are at their best when basking in full sun, which translates to a minimum of 6 hours of direct sunlight daily.

However, these hardy plants can tolerate some partial shade, particularly in regions with scorching summers. In such areas, providing shade during the hottest hours of the day can help prevent the plants from experiencing stress.

When Brussels sprouts receive the optimal amount of sunlight, they exhibit healthy growth, sturdy stalks, and the development of well-formed sprouts. When growing Brussels sprouts indoors or in a greenhouse, it’s advisable to offer as much light as possible, potentially utilizing grow lights or fluorescent lights to supplement natural sunlight.

Proper spacing in the garden is equally crucial, ensuring that each plant has enough room to soak up the essential sunlight for robust growth and sprout development.

Should I water Brussels sprouts every day?

Watering Brussels sprouts daily is generally unnecessary and may even be detrimental to their growth. These cool-weather vegetables prefer a consistent but not excessive moisture level in the soil. Rather than adhering to a fixed daily schedule, it’s best to water Brussels sprouts when the top inch of soil begins to dry out.

The frequency of watering will depend on various factors such as weather conditions, soil type, and the size of the plants. In hot and dry weather, more frequent watering may be necessary, while cooler and wetter periods may require less.

When you do water, it’s crucial to provide a deep and thorough soaking to encourage deep root growth. Morning watering is preferred to allow the foliage to dry before evening, reducing the risk of fungal diseases.

Applying mulch can help retain soil moisture and reduce the need for frequent watering. Brussels sprouts are relatively drought-tolerant once established, but it’s vital to ensure consistent moisture during their critical growth stages to support healthy development while avoiding overwatering, which can lead to problems like root rot.

Monitoring the soil’s moisture level and adjusting your watering schedule accordingly is key to successful Brussels sprout cultivation.

What Do Brussels Sprouts Taste Like?

Brussels sprouts have a distinctive taste that can be described as slightly bitter, nutty, and earthy. The flavor can vary based on factors like how they are prepared, the cooking method used, and the season in which they are harvested. Here are some details about the taste of Brussels sprouts:

  • Slight Bitterness: Brussels sprouts are known for their mild bitterness, which is a characteristic of many cruciferous vegetables. This bitterness can be appealing to some but off-putting to others. Cooking methods can help mellow the bitterness.
  • Nutty and Earthy: Along with the bitterness, Brussels sprouts also have a nutty and earthy flavor, which becomes more pronounced when they are roasted or sautéed. This nuttiness can be quite enjoyable when properly prepared.
  • Sweetness with Caramelization: When Brussels sprouts are roasted or seared, they can develop a natural sweetness as their natural sugars caramelize. This sweetness can balance the bitterness and create a delightful contrast.
  • Seasonal Variation: The taste of Brussels sprouts can vary depending on when they are harvested. They are often considered sweeter and milder when picked after a light frost, as the cold can convert some of their starches into sugars.
  • Pairing: Brussels sprouts are versatile and pair well with a variety of flavors. Common ingredients to complement their taste include bacon, garlic, balsamic vinegar, Parmesan cheese, and mustard. These pairings can enhance their overall flavor profile.
  • Texture: Besides taste, the texture of Brussels sprouts is worth noting. When cooked correctly, they are tender on the inside with a slightly crispy outer layer, making them enjoyable to bite into.

The taste of Brussels sprouts can be an acquired one for some, especially if they’ve had them prepared in a way they didn’t enjoy in the past. However, experimenting with different cooking methods and flavor pairings, like delicious homegrown herbs, can reveal their delicious potential. Many people come to appreciate the unique taste of Brussels sprouts as they explore various recipes and discover their preferred way of preparing this nutritious vegetable.

What are good growing companions for Brussels sprouts?

Companion planting can be a helpful gardening strategy to improve the health and productivity of your Brussels sprouts while deterring pests or encouraging beneficial insects. Here are some good companion plants for Brussels sprouts.

Brussel Sprouts Companion Plants

  • Beets: Beets are compatible with Brussels sprouts and can help repel certain pests that affect both crops, like the cabbage looper. Additionally, beets don’t compete for the same nutrients, as they have different root structures.
  • Nasturtiums: Nasturtiums are known for their ability to repel aphids, which can be a common pest for Brussels sprouts. Planting nasturtiums around your Brussels sprouts can help keep aphids at bay.
  • Onions and Alliums: Onions, garlic, and other members of the Allium family can deter pests like aphids and cabbage worms. Plant them near Brussels sprouts to provide a protective barrier.
  • Dill: Dill can attract beneficial insects, such as ladybugs and parasitic wasps, which prey on common Brussels sprout pests like aphids and caterpillars.
  • Marigolds: Marigolds are effective in repelling nematodes, which can be harmful to the roots of Brussels sprouts. Plant them nearby to protect your Brussels sprout plants.
  • Bush Beans: Bush beans, like green beans, can be good companions for Brussels sprouts. They help with nitrogen fixation, enriching the soil with essential nutrients that benefit Brussels sprouts.
  • Lettuce: Lettuce and other leafy greens can provide some shade to Brussels sprouts during hot weather, as well as filling empty spaces in your garden.
  • Herbs: Certain herbs like rosemary and sage can help deter cabbage moths and other pests that affect Brussels sprouts. Their aromatic foliage can serve as a natural repellent.
  • Mint: Mint can help deter aphids and cabbage moths. However, it’s important to note that mint is invasive and can spread quickly, so it’s best grown in containers or areas where it won’t take over your garden.

Remember that companion planting is not a guaranteed solution for all gardening challenges, and the effectiveness of these combinations can vary depending on your specific garden conditions and regional climate. It’s a good idea to observe your garden and make adjustments as needed to find the best companion plants for your Brussels sprouts.

What is the best way to harvest Brussels sprouts?

Harvesting Brussels sprouts is a straightforward process that ensures the best flavor and quality of this vegetable. First, you must wait for the Brussels sprouts to reach maturity, which typically takes 90-100 days after transplanting or 140-180 days from direct sowing, depending on the variety you’re growing. These mini cabbages develop along the main stem of the plant, starting from the bottom and working their way up.

To harvest them, begin at the bottom of the plant, where the sprouts are the largest and most mature, reaching about 1 to 1.5 inches in diameter. Use a sharp knife or garden pruners to make clean cuts just above the leaf bud from which the sprout is attached, taking care not to harm the growing tip or the adjacent leaves.

Importantly, leave the top growth of the plant intact, as this allows the smaller sprouts higher up the stem to continue to develop and mature, providing a more extended harvest period for your Brussels sprouts.

What’s in a name?

The name “Brussels sprouts” is derived from their association with the city of Brussels, which is the capital of Belgium. These small, green vegetables are believed to have been cultivated in the region that includes modern-day Belgium as early as the 13th century. They were later popularized and became well-known as a staple in Belgian cuisine.

The name “Brussels sprouts” likely indicates their historical origin and popularity in this region. In French, they are called “choux de Bruxelles,” which translates to “cabbages of Brussels.” Over time, this name was adopted in English as “Brussels sprouts.”

What is one thing you might not know about Brussels sprouts? 

One lesser-known fact about Brussels sprouts is that they are a relatively recent cultivar when compared to many other vegetables. While their close relatives, such as cabbage and kale, have been cultivated for thousands of years, Brussels sprouts were developed as a distinct vegetable in the late 16th century in what is now Belgium. They are believed to have been selectively bred from wild cabbage plants to produce the small, compact heads of leaves that we recognize as Brussels sprouts today.

This relatively recent development, in terms of vegetable domestication, highlights the continuous process of human innovation in agriculture and the creation of new cultivars to suit culinary preferences and nutritional needs. Despite their recent origin, Brussels sprouts have become a beloved and nutritious vegetable enjoyed in various cuisines around the world.
