How to Grow Brussels Sprouts

Brussels sprouts, those tiny cruciferous delights resembling miniature cabbages, are not only a nutritional powerhouse but also a fascinating vegetable to grow in your own garden. If you enjoy the rich, earthy flavor of Brussels sprouts and want to embark on a rewarding gardening journey, this comprehensive guide is here to assist you. From selecting the right varieties to harvesting these mini marvels, here’s a step-by-step process on how to grow Brussels sprouts.

1. Choosing Brussels Sprouts Varieties

Brussels sprouts come in various varieties, each with its unique characteristics. Some popular varieties to consider include:

  • Long Island Improved: A classic heirloom variety known for its reliable performance and tasty sprouts.
  • Churchill: Recognized for its disease resistance and ability to produce uniform, flavorful sprouts.
  • Nautic: A relatively new variety with a shorter growing season, making it suitable for regions with cooler climates.

Choose a variety based on your climate, available growing season, and taste preferences.

2. Timing is Crucial

Brussels sprouts are a cool-season crop, meaning they thrive in cooler temperatures. Timing your planting correctly is crucial for a successful harvest. Here’s a basic timeline:

  • Start Indoors: Begin Brussels sprouts indoors about 12 to 16 weeks before the last expected frost in your area. Use biodegradable seed pots to minimize transplant shock.
  • Transplanting: Transplant seedlings outdoors when they are about 4 to 6 weeks old and have developed a sturdy stem. This is typically 2 to 4 weeks before the last frost.
  • Fall Harvest: Brussels sprouts are often harvested in the fall when the sprouts are firm and have a rich color.

3. Sunlight and Soil Conditions

For optimal growth, Brussels sprouts require specific sunlight and soil conditions:

  • Sunlight: Brussels sprouts prefer full sun but can tolerate partial shade. Ensure they receive at least 6 hours of direct sunlight each day.
  • Soil: Plant Brussels sprouts in well-draining, nutrient-rich soil. The soil should have a slightly acidic to neutral pH level ranging from 6.0 to 7.5.

4. Planting Brussels Sprouts Seedlings

Transplanting seedlings is a critical step in growing Brussels sprouts:

  • Spacing: Plant Brussels sprouts about 24 to 36 inches apart in rows spaced at least 3 feet apart. This provides enough space for the plants to grow and allows for adequate air circulation.
  • Planting Depth: Bury the seedlings slightly deeper than they were in their seed pots. This helps provide stability and encourages root development.
  • Firm Soil: After planting, firm the soil around each seedling to ensure good soil-to-root contact.

5. Watering and Mulching

Proper watering is essential for Brussels sprouts, and mulching can help retain soil moisture:

  • Watering: Keep the soil consistently moist, especially during dry spells. Water at the base of the plants to avoid wetting the leaves, which can lead to fungal issues.
  • Mulching: Apply a layer of organic mulch, such as straw or wood chips, around the base of the Brussels sprout plants. Mulch helps retain moisture, suppress weeds, and regulate soil temperature.

6. Fertilizing Brussels Sprouts

Brussels sprouts are heavy feeders, and providing them with the right nutrients is crucial for a successful harvest:

  • Initial Fertilization: Prior to transplanting seedlings, mix well-rotted compost or aged manure into the soil. This provides a nutrient boost for the growing season.
  • Side-Dressing: As the plants grow, side-dress with a balanced fertilizer high in nitrogen. Apply the fertilizer when the plants are about 6 to 8 inches tall and again when they start forming sprouts.

7. Supporting Tall Stems

Brussels sprout plants can grow tall, and supporting them is essential to prevent bending or breaking:

  • Staking or Caging: Stake or cage the plants to provide support. This is especially important in windy areas or if you anticipate heavy rainfall.

8. Pruning and Topping

Pruning and topping Brussels sprouts plants can help improve yield and sprout development:

  • Pruning Leaves: As the lower leaves turn yellow, remove them to improve air circulation and reduce the risk of diseases.
  • Topping: Once the plants reach a height of about 20 inches, consider topping them by removing the terminal bud. This encourages the development of larger sprouts and prevents the plant from investing energy in growing taller.

9. Protecting from Pests

Brussels sprouts can be susceptible to certain pests, so vigilant monitoring is crucial:

  • Cabbage Worms: Keep an eye out for cabbage worms, which can damage leaves and sprouts. Use row covers or apply organic insecticides to control these pests.
  • Aphids: Hose off aphids with a strong stream of water or use insecticidal soap for control.

10. Harvesting Brussels Sprouts

Harvesting Brussels sprouts is a gradual process as the sprouts mature from the bottom of the plant upward:

  • Bottom-Up Harvesting: Start harvesting sprouts from the bottom of the plant once they reach a decent size (about 1 to 1.5 inches in diameter).
  • Frost Enhances Flavor: Brussels sprouts can withstand light frosts, and some gardeners even claim that a touch of frost enhances their flavor. However, harvest before a hard freeze to prevent damage.

11. Storing and Using Brussels Sprouts

Preserving and preparing Brussels sprouts for consumption involve a few key steps:

  • Refrigeration: Store harvested Brussels sprouts in the refrigerator. They can remain fresh for several weeks.
  • Freezing: Blanching Brussels sprouts before freezing helps maintain their color, flavor, and nutritional value. Freeze them in airtight containers or bags for long-term storage.
  • Cooking Methods: Enjoy Brussels sprouts roasted, sautéed, steamed, or added to various dishes for a nutritious and flavorful meal.

12. Overwintering Brussels Sprouts

In mild climates, Brussels sprouts can survive through the winter, and some gardeners even report improved flavor after exposure to frost:

  • Protecting from Frost: If you expect a hard freeze, cover Brussels sprout plants with frost blankets or row covers to protect them.


Growing Brussels sprouts is an engaging and rewarding experience, allowing you to savor the unique taste of these mini cabbages fresh from your garden. From careful timing and planting to diligent care and harvesting, each step contributes to a successful Brussels sprouts harvest. So, roll up your sleeves, embrace the joy of gardening, and cultivate your own crop of these delightful miniatures. Happy Brussels sprouts growing!
