Yes, you can grow tarragon in an outdoor plant box! Tarragon, a flavorful herb commonly used in French cuisine, thrives in well-drained soil and plenty of sunlight. Here’s how to ensure success:

1. Choose the Right Box: Opt for a plant box with good drainage holes to prevent waterlogging, as tarragon dislikes soggy roots. A depth of at least 12 inches is ideal for root development.

2. Soil Requirements: Use a light, sandy soil mix with added compost for nutrients. Tarragon prefers slightly alkaline soil with a pH of 6.5–7.5.

3. Sunlight: Place the box in a spot that receives 6–8 hours of sunlight daily. Tarragon loves warmth but can tolerate partial shade in hotter climates.

4. Watering: Water moderately, allowing the soil to dry slightly between waterings. Overwatering can lead to root rot.

5. Pruning and Harvesting: Regularly trim the plant to encourage bushier growth. Harvest leaves as needed, but avoid cutting more than one-third of the plant at once.

With proper care, your tarragon will flourish in an outdoor plant box, providing fresh herbs for your culinary creations. Happy gardening!
