How to Grow Tarragon Indoors (Fresh Flavor at Home)

Tarragon is a flavorful herb often used in French cooking, especially for sauces, fish, and chicken. While it’s less common than basil or mint, growing tarragon indoors is simple and highly rewarding. With the right care, you can enjoy fresh, aromatic leaves year-round right from your windowsill.

Why Grow Tarragon Indoors?

Unlike many herbs, tarragon can be tricky to find fresh at grocery stores, making it a fantastic choice for indoor gardening.

• Fresh supply anytime: No need to rely on store-bought herbs.

• Beginner-friendly: Hardy and adaptable to indoor conditions.

• Compact: Grows well in pots without taking up much space.

• Health benefits: Known for its antioxidants and digestive support.

Best Conditions for Growing Tarragon Indoors

To thrive, tarragon needs the right balance of light, soil, and temperature:

• Light: 6–8 hours of direct sun, or 12–14 hours with a grow light.

• Temperature: 18–24°C (65–75°F). It tolerates cooler nights but not frost.

• Soil: Well-draining, sandy or loamy potting mix.

• Container: 8–10 inch pot with drainage holes.

Planting Tarragon Indoors

Unlike basil or parsley, tarragon is best started from cuttings or young plants. Seeds are often unreliable (especially for French tarragon).

1. From cuttings: Take a 4–6 inch cutting from a healthy plant. Remove lower leaves and place the cutting in water or directly into moist soil until roots develop.
2. From starter plants: Many garden centers sell French or Russian tarragon plants ready for potting.
3. Division: If you have a larger outdoor plant, divide the root clump and transplant a section indoors.

Caring for Indoor Tarragon

Tarragon is low-maintenance once established.

• Watering: Allow the top inch of soil to dry between waterings. Overwatering can cause root rot.

• Fertilizer: Feed lightly once a month with a balanced liquid fertilizer.

• Pruning: Regularly trim stems to encourage bushier growth and prevent legginess.

• Air circulation: Place near a window or use a small fan to reduce humidity and prevent mildew.

Harvesting Tarragon Indoors

• Begin harvesting once the plant reaches 6–8 inches tall.

• Snip stems just above a leaf node to promote regrowth.

• Use fresh leaves immediately or dry them for storage.

• Tarragon leaves are strongest in flavor right before the plant flowers.

Best Types of Tarragon for Indoor Growing

• French Tarragon: Best for cooking; prized for its flavor. Grown from cuttings or plants, not seeds.

• Russian Tarragon: Easier to grow from seed, but flavor is weaker.

• Mexican Tarragon (Tagetes lucida): A different species with an anise-like flavor, more tolerant of heat.

Common Problems When Growing Tarragon Indoors

• Leggy plants: Not enough sunlight. Move closer to a window or use grow lights.

• Powdery mildew: Common in stagnant air; improve circulation.

• Weak flavor: Russian tarragon tends to taste milder than French tarragon.
