Yes, you can grow dwarf patchouli plants in an outdoor plant box, provided you meet their basic growing requirements. Dwarf patchouli (Pogostemon heyneanus) is a compact variety of the aromatic herb, making it ideal for container gardening.

To ensure healthy growth, choose a well-draining plant box with ample space for root development. Patchouli thrives in partial shade to full sun, so place the box in a spot that receives at least 4-6 hours of sunlight daily. Use a rich, loamy soil mix with good moisture retention but avoid waterlogging.

Water the plants regularly to keep the soil consistently moist, especially during dry spells. Fertilize monthly with a balanced organic fertilizer to promote lush foliage. Dwarf patchouli also benefits from occasional pruning to maintain its bushy shape and encourage new growth.

With proper care, your outdoor plant box can become a fragrant haven of dwarf patchouli, perfect for adding a tropical touch to patios, balconies, or gardens.
