Benefits of Planting Together

• Pest Repellent Properties: Nasturtiums effectively repel aphids, whiteflies, and other pests, protecting nearby pepper plants. Rosemary’s aromatic oils deter certain insects, further boosting pest control.
• Improved Flavor and Growth: Some gardeners believe that rosemary enhances the flavor of peppers, although this is anecdotal. The diverse plant mix can also promote a balanced ecosystem, aiding growth.
• Space Efficiency: By combining upright (peppers), bushy (rosemary), and trailing (nasturtiums) growth habits, you maximize vertical and horizontal space in your garden.
• Soil Health Benefits: Nasturtiums can improve soil quality by fixing nitrogen, benefiting nutrient uptake for peppers and rosemary.
• Pollinator Attraction: Nasturtiums attract pollinators like bees, which can enhance the pollination of pepper plants.

Potential Challenges

• Resource Competition: While their nutrient needs are compatible, ensure proper spacing to prevent competition for water and nutrients.
• Watering Needs: Rosemary prefers drier conditions than peppers and nasturtiums. Consider adjusting watering strategies to accommodate all three.
• Disease Susceptibility: Monitor for diseases like powdery mildew, which can affect nasturtiums and spread to nearby plants.
• Harvesting Considerations: Stagger planting times to ensure easy access for harvesting each plant without disturbing others.

Planting Tips & Best Practices

• Optimal Spacing: Maintain recommended spacing to ensure each plant receives adequate sunlight and airflow. Consider planting nasturtiums at the garden’s edge to allow their trailing habit to spread naturally.
• When to Plant: Plant after the last frost date in your area when soil temperatures are consistently warm.
• Container vs. Garden Bed: All three plants can thrive in containers or garden beds. Ensure containers have drainage holes and are large enough to accommodate root growth.
• Soil Preparation: Amend soil with compost to improve drainage and nutrient content. Test soil pH to ensure it falls within the suitable range for all plants.
• Companion Plants: Basil and marigolds pair well with peppers and rosemary, providing additional pest control and aesthetic appeal.
