Benefits of Planting Together

• Pest Repellent Properties: Oregano’s aromatic oils can deter pests that might otherwise target lettuce and radishes.
• Improved Growth: Radishes can help break up the soil, improving aeration and drainage for lettuce.
• Space Efficiency: The varied growth habits of these plants allow for efficient use of space.
• Soil Health Benefits: Radishes can improve soil structure, benefiting the root systems of lettuce and oregano.
• Pollinator Attraction: Oregano flowers attract pollinators, which can benefit the entire garden ecosystem.

Potential Challenges

• Competition for Resources: While these plants have different needs, they can still compete for water and nutrients if not properly spaced.
• Different Watering Needs: Oregano prefers drier conditions, whereas lettuce and radishes need more consistent moisture.
• Disease Susceptibility: Close planting can increase the risk of disease spread.
• Harvesting Considerations: Radishes mature quickly and may need to be harvested before lettuce is fully grown.

Solutions: Use mulch to retain soil moisture and reduce competition. Plant in raised beds to improve drainage and air circulation.

• Optimal Spacing: Ensure adequate spacing based on the table above to prevent overcrowding.
• Timing: Plant lettuce and radishes in early spring or fall; oregano can be planted in late spring.
• Container vs. Garden Bed: All three can be grown in containers, but ensure they have enough depth for radish roots.
• Soil Preparation: Amend soil with compost to improve fertility and drainage.
• Companion Plants: Consider adding carrots or onions, which also pair well with these plants.
