Lemongrass (Cymbopogon citratus) Care Guide
Lemongrass is a fast-growing, tropical herb known for its citrusy aroma and culinary versatility. It thrives in warm climates and can be grown in garden beds or containers.
Growing Conditions:
- Sun: Full sun (at least 6-8 hours per day)
- Soil: Well-draining, fertile soil with a slightly acidic to neutral pH (6.0-7.5)
- Watering: Keep soil consistently moist but not waterlogged
- Temperature: Prefers warm climates (above 40°F); not frost-hardy
- Hardiness Zones: 9-11 (can be grown as an annual or overwintered indoors in colder zones)
- Spacing: 24 inches apart, as it forms large clumps
- Container Growing: Use a large pot (at least 12 inches wide) with good drainage
Planting & Propagation:
- From Cuttings: Root fresh stalks in water before planting in soil.
- From Seeds: Start indoors in early spring; seeds take longer to establish.
- Division: Established plants can be divided by separating clumps and replanting.
Maintenance & Harvesting:
- Pruning: Trim older, woody stalks to encourage fresh growth.
- Fertilizing: Use a balanced fertilizer every 4-6 weeks during the growing season.
- Harvesting: Cut outer stalks at the base once they reach 12-24 inches tall. Use fresh or dried in teas, soups, and curries.
Overwintering:
- In Cold Climates: Before the first frost, bring potted plants indoors or dig up and store roots in a cool, dry place.
- Indoors: Place in a bright, sunny location and reduce watering during winter dormancy.
