Can You Plant Garlic, Marigolds, and Nasturtiums Together?

Companion planting is a beloved gardening technique that involves growing different plants together for mutual benefit. Gardeners often consider this approach for its potential to enhance growth, deter pests, and improve yields. In this article, we’ll explore whether garlic, marigolds, and nasturtiums can be planted together, and what you need to know to make the most of their companionship.

Compatibility Analysis

Yes, you can plant garlic, marigolds, and nasturtiums together. These plants complement each other well in the garden, offering a range of benefits that make them excellent companions.

• Growth Requirements: All three plants thrive in similar conditions, preferring full sun and well-drained soil. Their compatibility is rooted in their ability to coexist without competing heavily for resources.

• Pest Control: Garlic is known for its natural pest-repellent properties, which can help protect marigolds and nasturtiums from common garden pests. Marigolds, in turn, are renowned for deterring nematodes, while nasturtiums attract aphids away from other plants, serving as a trap crop.

• Nutrient Needs and Spacing: These plants have relatively low nutrient demands and can be spaced appropriately to avoid overcrowding. Garlic grows vertically, marigolds are bushy, and nasturtiums spread low, allowing them to share space efficiently.

• Different Watering Needs: Nasturtiums prefer slightly drier conditions compared to garlic and marigolds, which may require careful watering management.

• Disease Susceptibility: Each plant has its own disease susceptibilities, so monitoring for specific issues like fungal infections is crucial.

• Harvesting Considerations: Garlic’s harvest time may coincide with peak flowering periods for marigolds and nasturtiums, requiring careful harvesting to avoid damaging the other plants.

Solutions: Use mulch to retain moisture, stagger planting times, and ensure adequate spacing to minimize competition and disease spread.

Planting Tips & Best Practices

• When to Plant: Garlic is typically planted in the fall, while marigolds and nasturtiums can be planted in spring after the last frost.

• Container vs. Garden Bed: These plants can thrive in both containers and garden beds, but ensure containers are large enough to accommodate their growth.

• Soil Preparation Tips: Amend soil with compost to improve fertility and drainage. Ensure a pH balance suitable for all three plants.

• Additional Companions: Consider adding basil or chives, which also pair well with garlic, marigolds, and nasturtiums.
