Benefits of Planting Together

Planting tomatoes, peas, and lemongrass together can offer several advantages:

• Pest Repellent Properties: Lemongrass emits a citrus scent that deters pests like mosquitoes and aphids, providing a natural shield for tomatoes and peas.
• Improved Growth: Peas fix nitrogen in the soil, which can enhance tomato growth, leading to a more bountiful harvest.
• Space Efficiency: Vertical growth of peas and the upright habit of tomatoes allow for efficient use of space, while lemongrass can fill in gaps.
• Soil Health Benefits: The nitrogen-fixing ability of peas enriches the soil, benefiting the nutrient needs of tomatoes.

Potential Challenges

While these plants can be grown together, there are challenges to consider:

• Competition for Resources: Tomatoes and lemongrass may compete for sunlight if not spaced properly. Ensure adequate spacing to avoid shading.
• Different Watering Needs: While all require moderate watering, peas prefer slightly cooler, moister conditions than tomatoes and lemongrass.
• Disease Susceptibility: Tomatoes are prone to blight, which can spread if not managed. Rotate crops and monitor for signs of disease.
• Harvesting Considerations: Peas and tomatoes have different harvest times, so plan accordingly to avoid disturbing each plant.

Planting Tips & Best Practices

• Optimal Spacing: Ensure tomatoes are spaced 18-24 inches apart, with peas 2-3 inches apart, and lemongrass 24 inches from other plants.
• Timing: Plant peas early in the season, followed by tomatoes and lemongrass as temperatures rise.
• Container vs. Garden Bed: Use raised beds for better drainage and soil management or containers for lemongrass in cooler zones.
• Soil Preparation: Amend soil with compost to enhance fertility and drainage, crucial for all three plants.
• Companion Plants: Basil and marigolds can also be planted nearby to further deter pests and enhance growth.
