Growing turmeric in outdoor plant boxes can be a rewarding experience, especially when paired with the right companion plants. Turmeric thrives in warm, humid conditions and benefits from plants that improve soil health, deter pests, and provide shade. Here are some of the best plants to grow alongside turmeric in outdoor plant boxes:

1. Ginger: A close relative of turmeric, ginger shares similar growing conditions and helps create a microclimate that retains moisture.

2. Lemongrass: This aromatic plant repels pests and complements turmeric’s growth with its tall, grassy structure.

3. Basil: Known for its pest-repellent properties, basil also enhances soil fertility and adds flavor to your garden.

4. Marigolds: These vibrant flowers deter nematodes and other soil-borne pests, protecting turmeric roots.

5. Spinach: A low-growing leafy green that provides ground cover, reducing weed competition and retaining soil moisture.

For optimal results, ensure your outdoor plant boxes have well-draining soil, partial shade, and regular watering. By choosing the right companion plants, you can create a thriving turmeric garden that’s both productive and visually appealing. Happy gardening!
