Creating a mini tarragon garden in an outdoor plant box is a rewarding way to grow this flavorful herb at home. Follow these simple steps to ensure success:

1. Choose the Right Plant Box: Select a well-draining container at least 12 inches deep to accommodate tarragon’s roots. Ensure it has drainage holes to prevent waterlogging.

2. Pick the Perfect Spot: Tarragon thrives in full sun (6-8 hours daily) but tolerates partial shade. Place your plant box in a sunny, sheltered location to protect it from strong winds.

3. Prepare the Soil: Use a light, nutrient-rich potting mix with good drainage. Avoid heavy soils, as tarragon prefers slightly sandy conditions. A pH of 6.0-7.5 is ideal.

4. Planting Tarragon: Space tarragon plants 12-18 inches apart to allow for growth. If starting from seeds, sow them shallowly and keep the soil moist until germination. Alternatively, transplant young plants for quicker results.

5. Watering and Care: Water tarragon moderately, letting the soil dry slightly between waterings. Overwatering can cause root rot. Mulch lightly to retain moisture and suppress weeds.

6. Fertilizing: Feed with a balanced organic fertilizer every 4-6 weeks during the growing season. Avoid excessive nitrogen, which can reduce flavor.

7. Pruning and Harvesting: Trim tarragon regularly to encourage bushier growth. Harvest leaves as needed, preferably in the morning when oils are most concentrated.

8. Winter Care: In colder climates, move the plant box indoors or cover it to protect tarragon from frost.

With these tips, your mini tarragon garden will flourish, providing fresh herbs for culinary delights year-round!
