Yes, you can grow dwarf lemongrass plants in an outdoor plant box! Dwarf lemongrass (Cymbopogon citratus) is a compact variety of the popular herb, making it ideal for container gardening. Here’s how to ensure success:

1. Choose the Right Plant Box: Select a sturdy, well-draining container at least 12 inches deep to accommodate the roots.

2. Soil Requirements: Use a lightweight, nutrient-rich potting mix with good drainage to prevent waterlogging.

3. Sunlight Needs: Place the plant box in a sunny spot where the lemongrass receives at least 6 hours of direct sunlight daily.

4. Watering Tips: Keep the soil consistently moist but not soggy. Water when the top inch of soil feels dry.

5. Fertilization: Feed with a balanced, slow-release fertilizer every 4-6 weeks during the growing season.

6. Winter Care: In colder climates, move the plant box indoors or protect it from frost to overwinter.

Dwarf lemongrass adds a refreshing citrusy aroma to your garden and is perfect for culinary use. With proper care, your outdoor plant box can yield a thriving lemongrass harvest!
