Can You Plant Broccoli, Beets, and Sweet Potatoes Together?

Companion planting is a gardening technique that involves growing different plants close together for mutual benefits. Gardeners often consider this method to optimize space, improve plant health, and increase yields. In this article, we’ll explore whether broccoli, beets, and sweet potatoes can be successfully grown together. You’ll learn about their compatibility, growing requirements, benefits, potential challenges, and best practices.

Compatibility Analysis

The short answer is: No, broccoli, beets, and sweet potatoes are not ideal companions.

Broccoli, a member of the Brassica family, has specific nutrient and space requirements that differ significantly from those of beets and sweet potatoes. Beets, which are root vegetables, and sweet potatoes, which are sprawling vines, also have distinct needs. The key factors at play here include:

• Growth Requirements: Broccoli prefers cooler temperatures and requires ample space for its large leaves. Beets are more adaptable but thrive in cooler weather. Sweet potatoes need warm temperatures and plenty of room to spread.
• Pest Control: Broccoli is susceptible to pests like cabbage worms, while sweet potatoes can attract sweet potato weevils. Beets generally face fewer pest issues but can suffer from leaf miners.
• Nutrient Needs: Broccoli is a heavy feeder, demanding high nitrogen levels, while beets and sweet potatoes have more moderate nutrient requirements.
• Spacing: Broccoli requires significant spacing due to its large size, which can overshadow beets and sweet potatoes.

Benefits of Planting Together

While these three plants aren’t the best companions, planting them with other suitable companions can offer benefits:

• Pest Repellent Properties: Broccoli can benefit from being planted near herbs like dill, which repel cabbage moths.
• Improved Flavor or Growth: Beets grow well with onions and garlic, which can enhance their flavor.
• Space Efficiency: Interplanting beets with onions or radishes can maximize garden space.
• Soil Health Benefits: Sweet potatoes can be paired with nitrogen-fixing plants like beans to improve soil fertility.
• Pollinator Attraction: Flowers like marigolds can be planted nearby to attract pollinators and deter pests.

Potential Challenges

• Competition for Resources: Broccoli’s large leaves can overshadow smaller plants like beets.
• Different Watering/Feeding Needs: Broccoli’s high nitrogen requirements can lead to nutrient imbalances for sweet potatoes.
• Disease Susceptibility: Broccoli and beets can be susceptible to fungal diseases if not spaced properly.
• Harvesting Considerations: Beets and sweet potatoes have different harvest times, complicating garden planning.
• Practical Solutions: Use raised beds or containers to manage different soil needs and optimize spacing.

Planting Tips & Best Practices

• Optimal Spacing: Ensure adequate spacing to prevent competition and disease spread.
• When to Plant: Plant broccoli in early spring or fall, beets in spring or fall, and sweet potatoes in late spring.
• Container vs. Garden Bed: Consider containers for sweet potatoes to control their spread.
• Soil Preparation Tips: Amend soil with compost to provide balanced nutrients.
• Companion Plants: Pair broccoli with herbs like dill and chamomile; beets with onions and garlic; sweet potatoes with beans.
