Can You Plant Peas, Blueberries, and Nasturtiums Together?

Companion planting is a popular gardening technique that involves growing different plants together to enhance growth, deter pests, and improve soil health. Gardeners often wonder about the compatibility of certain plants, such as peas, blueberries, and nasturtiums. In this article, we’ll explore whether these three can thrive together and how to make the most of your garden space.

Compatibility Analysis

The short answer is: Yes, you can plant peas, blueberries, and nasturtiums together, but with some considerations. Each plant has unique requirements and benefits, making them suitable companions under the right conditions.

• Peas: These legumes are nitrogen-fixers, enriching the soil for other plants. They prefer cool weather and well-drained soil.
• Blueberries: These shrubs thrive in acidic soil and need full sun to partial shade.
• Nasturtiums: Known for their pest-repellent properties, nasturtiums can grow in poor soil and are excellent for attracting pollinators.

Key Factors

• Growth Requirements: Peas and nasturtiums can share similar soil conditions, but blueberries require more acidic soil.
• Pest Control: Nasturtiums deter aphids and other pests, benefiting peas and blueberries.
• Nutrient Needs: Peas contribute nitrogen to the soil, which can benefit nasturtiums but not blueberries due to their specific soil pH needs.
• Spacing: Ensure adequate space to prevent competition and allow each plant to thrive.

Benefits of Planting Together

• Pest Repellent Properties: Nasturtiums deter pests like aphids, protecting peas and blueberries.
• Improved Growth: Peas enrich the soil with nitrogen, benefiting nasturtiums.
• Space Efficiency: Utilizing vertical space with peas and ground cover with nasturtiums maximizes garden space.
• Pollinator Attraction: Nasturtiums attract pollinators, enhancing fruit production in blueberries.

Potential Challenges

• Resource Competition: Blueberries may compete for water and nutrients with other plants.
• Different Soil Needs: Blueberries require acidic soil, unlike peas and nasturtiums.
• Disease Susceptibility: Monitor for diseases that can spread among plants.
• Harvesting Considerations: Stagger planting times to avoid overlapping harvests.

Practical Solutions

• Use separate containers or raised beds for blueberries to maintain acidic soil.
• Mulch around blueberries to retain moisture and acidity.
• Plant nasturtiums as a border to deter pests without affecting soil pH.

Planting Tips & Best Practices

• Optimal Spacing: Ensure peas have trellises for support, and give blueberries ample space.
• Timing: Plant peas in early spring, blueberries in early spring or fall, and nasturtiums after the last frost.
• Container vs. Garden Bed: Use containers for blueberries to control soil pH.
• Soil Preparation: Amend soil with sulfur for blueberries, and ensure good drainage for peas and nasturtiums.
• Companion Plants: Consider adding marigolds or borage, which also benefit from companion planting.
