Benefits of Planting Together

Planting rosemary and alyssum together offers several advantages. Alyssum’s ability to attract pollinators and beneficial insects like hoverflies can help control aphid populations, indirectly protecting rosemary. Additionally, alyssum’s dense ground cover can help suppress weeds, maintaining soil health and moisture levels. This pairing also maximizes space efficiency, as the upright rosemary grows above the spreading alyssum.

Potential Challenges

While rosemary and alyssum generally coexist well, there are potential challenges to consider. Rosemary’s drought tolerance means it prefers less frequent watering than alyssum, which may require more consistent moisture. To address this, consider planting them in separate containers or using a drip irrigation system to manage differing water needs. Additionally, ensure proper spacing to prevent overcrowding and competition for sunlight.

Planting Tips & Best Practices

• Optimal Spacing: Plant rosemary 18-24 inches apart and alyssum 6-12 inches apart.
• Timing: Plant both after the last frost in spring when the soil has warmed.
• Container vs. Garden Bed: Both plants can thrive in containers, providing flexibility in garden design.
• Soil Preparation: Use well-draining soil, enriched with organic matter for optimal growth.
• Companion Plants: Consider adding lavender or sage, which also pair well with rosemary and alyssum.
