Did You Know?

1. Brussels sprouts belong to the same family as cabbage, broccoli, and kale, known as the Brassicaceae family.

2. When planting Brussels sprouts, it is recommended to space them about 24 to 36 inches apart in rows, giving each plant enough room to grow and spread.

3. Brussels sprouts should be planted in late spring or early summer, as they thrive in cooler temperatures around 50 to 75°F (10 to 24°C).

4. A single Brussels sprout plant can produce up to two pounds of sprouts throughout its growing season, which typically lasts around 90 to 120 days.

5. To encourage optimal growth, it is beneficial to remove the lower leaves of Brussels sprout plants as they grow. This allows more nutrients and energy to be directed toward the development of larger, more flavorful sprouts.

Planting And Spacing Brussels Sprout Seeds

When it comes to planting brussel sprouts, proper spacing is important for optimal growth and yield. Brussel sprout seeds should be sown one-fourth to one-half inch deep, 4 inches apart in rows or raised beds. This spacing allows each plant to have enough space to grow and develop fully without overcrowding. It is crucial to give each plant adequate space to ensure proper air circulation and sunlight exposure.

After planting the seeds, patience is key as it takes up to a week for them to sprout. Once the seedlings emerge and have two sets of leaves, thinning is necessary. You should thin the seedlings to 1-2 foot spacing between plants. This thinning process eliminates weaker plants and allows the remaining ones to have abundant space to thrive and develop into robust brussel sprout plants.

Bonnie Plants, a popular brand for vegetable transplants, recommends spacing their brussel sprout plants 18 to 24 inches apart in the garden. Following their guidelines ensures that your plants have ample space to grow and avoids overcrowding which can lead to stunted growth and an increased risk of disease.

Care And Maintenance For Growing Brussels Sprouts

Growing brussel sprouts requires proper care and maintenance to ensure healthy plant growth and a plentiful harvest. After planting the seeds or transplanting seedlings, it is essential to water thoroughly to provide the plants with enough moisture. This initial watering helps settle the soil around the roots and promotes healthy establishment.

To help retain moisture and suppress weeds, mulching is highly recommended. Adding a layer of mulch around the base of each brussel sprout plant, approximately 2-3 inches thick, prevents evaporation and conserves moisture in the soil. Additionally, mulching helps control weed growth, reducing competition for nutrients and water.

While staking is not initially necessary, it may become necessary as the plants grow taller and become top-heavy. In such cases, you can stake each plant individually using a bamboo stake, wooden stake, or rebar and twine. Staking provides support and prevents the plants from falling over or bending under their own weight. By ensuring the proper structural integrity, you are nurturing healthy and upright brussel sprout plants.

  • Thoroughly water the plants after planting or transplanting.
  • Add a layer of mulch around each plant to retain moisture and suppress weeds.
  • Stake the plants if they become tall and top-heavy to provide support and prevent bending or falling over.

Watering And Feeding Brussels Sprout Plants

Regular and adequate watering is crucial for the growth and development of brussel sprout plants. It is recommended to check the soil regularly and water when the top inch is dry. Monitoring the weather conditions is important as watering frequency may vary. Proper watering ensures that the plants receive the necessary moisture to thrive, as brussel sprouts prefer consistently moist soil.

In addition to regular watering, feeding brussel sprout plants is vital for optimal growth. One month after planting, it is recommended to start feeding the plants. Using a reliable plant food can provide essential nutrients for healthy growth. One option is to use Miracle-Gro soil and plant food together for optimal results. The combination of a balanced soil mix and a nutrient-rich plant food creates an ideal environment for robust brussel sprout growth.

  • Regular and adequate watering is crucial for brussel sprout growth.
  • Check soil regularly and water when the top inch is dry.
  • Monitor weather conditions to adjust watering frequency.
  • Feeding brussel sprout plants one month after planting is recommended.
  • Use reliable plant food, such as Miracle-Gro soil and plant food, for optimal growth.
  • Apply Miracle-Gro Performance Organic Edibles Plant Nutrition Granules every six weeks for continuous nutrient supply.

Managing Pests: Controlling Cabbage Worms

One of the challenges faced by many brussel sprout growers is the presence of cabbage worms. These pests can damage the leaves and negatively impact the plant’s overall health. Fortunately, there are effective methods for managing cabbage worms and keeping them under control.

Dusting the plants with Bt (Bacillus thuringiensis) is a natural and safe way to control cabbage worms. Bt is a highly targeted and specific biopesticide that affects only the digestive systems of caterpillars, including cabbage worms. By dusting the plants with Bt, you can effectively reduce the cabbage worm population and protect the foliage of your brussel sprouts.

In cases where cabbage worms are visible, they can be removed by handpicking or dropping them into a container filled with soapy water. This method acts as a physical control measure and helps to eliminate the pests before they can cause significant damage to your brussel sprout plants.

Harvesting And Maintaining Brussels Sprouts

After patiently nurturing your brussel sprout plants, you will eventually reach the exciting time of harvesting. Brussels sprouts are ready for harvest when the sprouts are firm and reach a desirable size, typically around 1 to 2 inches in diameter. Harvesting can begin from the bottom of the stalk, picking the sprouts as they mature.

To maintain the health and productivity of your brussel sprout plants, proper maintenance is key. Regularly inspect the plants for signs of disease or pest infestations. Remove any damaged or yellowing leaves to maintain a clean and healthy plant. Additionally, continue to provide the necessary care, including watering, feeding, and staking if required, until the end of the growing season.

With proper planting, spacing, care, and maintenance, you can achieve optimal growth and a bountiful yield of delicious brussel sprouts. By following these guidelines and incorporating the suggested tips, you are well on your way to successfully growing your own brussel sprouts and enjoying the rewards of your hard work and dedication.

Frequently Asked Questions

How much space do brussel sprouts need?

Brussels sprouts require a significant amount of space to grow properly. They should be planted about 18 to 24 inches apart in a row or bed to allow enough room for their growth. Additionally, when planting in rows, it is crucial to space the rows 30 inches apart to provide sufficient walking space. It is important to monitor the seedlings closely to prevent them from drying out or becoming stunted before transplanting them into their final location.

Do brussel sprouts need a lot of water?

Brussel sprouts generally require a moderate amount of water for healthy growth. It is best to water them deeply but infrequently, aiming to maintain even soil moisture. Typically, 1-2 inches of water per week is sufficient. If possible, using drip irrigation can help save water, while applying mulch around the plant aids in retaining soil moisture and minimizing weed growth.

How many brussel sprout seeds to plant per hole?

To achieve optimal growth, it is recommended to plant 3 brussel sprout seeds per hole. This method allows for the thinning of the plants to ensure that only one plant remains in each spot. By doing so, the crop will be able to receive sufficient nutrients and water to foster steady growth. Additionally, it is crucial to fertilize and irrigate the brussel sprouts consistently, especially in dry weather, to maintain their well-being and productivity.

How many brussel sprouts do you get off one plant?

Once the vibrant leaves take on a yellow hue, gently remove them, ensuring to leave a 2-inch stalk for better sprout development. When the compact heads measure 1 to 2 inches in diameter and feel firm, they are ready to be harvested. With each plant offering a bountiful yield, expect to gather anywhere from 60 to 100 brussels sprouts per plant.
