Yes, you can grow citronella in an outdoor plant box! Citronella, known for its mosquito-repellent properties, thrives in containers when given the right conditions. Here’s how to do it successfully:

1. Choose the Right Plant Box: Opt for a spacious container with drainage holes to prevent waterlogging. A 12-inch-deep box is ideal for root growth.

2. Soil Requirements: Use well-draining potting soil mixed with compost for nutrients. Citronella prefers slightly acidic to neutral pH levels.

3. Sunlight: Place the plant box in a spot with 6-8 hours of sunlight daily. Citronella loves warmth but appreciates partial shade in scorching climates.

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

5. Maintenance: Trim leggy stems to encourage bushiness and remove dead leaves. Fertilize monthly during the growing season with a balanced liquid fertilizer.

Growing citronella in a plant box not only adds greenery to your space but also naturally deters mosquitoes. With proper care, your citronella plant will flourish outdoors!
