Growing galangal in outdoor plant boxes can be a rewarding experience, especially when paired with the right companion plants. Galangal, a tropical rhizome related to ginger, thrives in warm, humid conditions with well-draining soil. To create a flourishing galangal garden, consider these ideal plants for your outdoor plant boxes:

1. Lemongrass – A perfect companion, lemongrass shares similar growing conditions and helps deter pests.

2. Turmeric – Another rhizome that enjoys the same warm, moist environment as galangal.

3. Thai Basil – This aromatic herb complements galangal in both growth and culinary use.

4. Kaffir Lime – Its citrusy leaves pair well with galangal in cooking and enjoy similar tropical conditions.

5. Chili Peppers – These add vibrancy and thrive in the same sunny, well-drained soil.

For optimal growth, ensure your plant boxes have rich, loamy soil and partial shade to protect galangal from intense midday sun. Regular watering and mulching will help retain moisture, mimicking its native tropical habitat. By selecting these companion plants, you’ll create a thriving, productive galangal garden in your outdoor plant boxes.
