The Ultimate Guide to Companion Planting for Brussel Sprouts

Why Companion Planting is Important for Brussel Sprouts?

Companion planting is a sustainable way to grow healthy plants without relying on chemical fertilizers or pesticides. By planting different species together, we can create a balanced ecosystem that supports the growth of each plant. When it comes to growing Brussel sprouts, companion planting is crucial for several reasons.

Firstly, Brussel sprouts are susceptible to various pests and diseases, such as aphids, cabbage worms, and flea beetles. Companion planting can help repel these pests naturally by using plants that have insect-repelling properties.

Secondly, Brussel sprouts require a lot of nutrients to grow healthy and strong. Companion planting can help improve soil fertility by using plants that fix nitrogen or have deep roots that draw nutrients up from deeper soil layers.

Lastly, companion planting can enhance the flavor and aroma of Brussel sprouts by using herbs that complement their taste.

The Best Companion Plants for Brussel Sprouts

Now that we know why companion planting is important let's take a look at some of the best companion plants for Brussel sprouts.

1. Carrots

Carrots and Brussel sprouts make excellent companions because they have similar soil requirements. Carrots also help improve soil structure by breaking up hard soils, allowing air and water to penetrate more easily.

How to Plant:

Plant carrots between the rows of Brussel sprouts. Make sure to keep the soil moist, and thin out the carrots as needed to prevent overcrowding.

2. Dill

Dill is an excellent companion plant for Brussel sprouts because it attracts beneficial insects like ladybugs, lacewings, and hoverflies that prey on common pests like aphids and cabbage worms.

How to Plant:

Plant dill near your Brussel sprouts in a sunny location. Be careful not to plant too much dill, as it can attract harmful insects in large amounts.

3. Borage

Borage is a beautiful flowering herb that attracts pollinators like bees and butterflies. It also repels harmful insects like tomato hornworms and cabbage worms.

How to Plant:

Plant borage near your Brussel sprouts in a sunny location. Borage can grow quite large, so make sure to give it enough space to spread out.

4. Nasturtiums

Nasturtiums are a colorful and edible flower that can help repel pests like aphids and whiteflies. They also attract beneficial insects like hoverflies and ladybugs.

How to Plant:

Plant nasturtiums around the perimeter of your Brussel sprouts. You can also interplant them between rows.

5. Chamomile

Chamomile is a fragrant herb that attracts beneficial insects like hoverflies and parasitic wasps. It also has antibacterial properties that can help prevent disease in your Brussel sprouts.

How to Plant:

Plant chamomile near your Brussel sprouts in a sunny location. Chamomile prefers well-draining soil, so make sure to plant it in a raised bed if your soil is heavy.

Companion Plants to Avoid

While some plants can be beneficial for Brussel sprouts, others can harm their growth or attract harmful pests. Here are some companion plants to avoid planting near your Brussel sprouts:

1. Tomatoes

Tomatoes and Brussel sprouts should never be planted together because they both attract the same pests, such as aphids and whiteflies. Planting them together can lead to a massive infestation that can destroy both crops.

2. Pole Beans

Pole beans are not suitable companion plants for Brussel sprouts because they compete for the same nutrients in the soil. Pole beans are also known to attract bean beetles, which can harm your Brussel sprouts.

3. Mustard Greens

Mustard greens are members of the brassica family, just like Brussel sprouts. Planting them together can lead to an increased risk of disease, as they are both susceptible to the same fungal and bacterial infections.

Tips for Successful Companion Planting

Companion planting requires careful planning and consideration to ensure that each plant benefits from its surrounding species. Here are some tips to help you succeed in companion planting for Brussel sprouts:

1. Choose Complementary Plants

Choose companion plants that have different nutrient requirements and pest-resistant properties than your Brussel sprouts. This will create a diverse ecosystem that supports the growth of each plant.

2. Pay Attention to Spacing

Make sure to give each plant enough space to grow without overcrowding. Overcrowding can lead to competition for resources and increased risk of disease.

3. Rotate Your Crops

Rotate your crops every year to prevent soil-borne diseases and pests from building up in the soil. This will also help improve soil fertility by allowing different plants to replenish nutrients.
