Creating a thriving lemongrass garden in outdoor plant boxes requires careful selection of companion plants that complement its growth and enhance its aromatic qualities. Lemongrass, a tropical herb, thrives in warm, sunny conditions and pairs well with plants that share similar needs. Here are the best plants to grow alongside lemongrass in outdoor plant boxes:

1. Basil – This fragrant herb enjoys full sun and well-draining soil, making it an ideal companion. Its pest-repellent properties also benefit lemongrass.

2. Mint – A hardy herb that grows well in containers, mint helps deter pests while adding freshness to your garden. Be sure to plant it in a separate pot to control its spread.

3. Marigolds – These vibrant flowers repel harmful insects and attract pollinators, creating a healthier environment for lemongrass.

4. Cilantro – Another sun-loving herb, cilantro grows well with lemongrass and adds culinary versatility to your garden.

5. Lavender – Known for its soothing fragrance, lavender thrives in similar conditions and enhances the visual appeal of your plant box.

For optimal growth, ensure your plant boxes have proper drainage and receive at least 6-8 hours of sunlight daily. Regular watering and occasional fertilization will keep your lemongrass and its companions flourishing. By choosing the right plants, you can create a lush, aromatic outdoor garden that’s both functional and beautiful.
