Growing Lemongrass From Seed: A Comprehensive Guide
Lemongrass (Cymbopogon citratus) is a fragrant, tropical herb prized for its citrusy aroma and culinary uses, especially in Southeast Asian cuisine. While often grown from divisions, starting lemongrass from seed is a rewarding yet challenging endeavor. This guide provides expert insights, practical tips, and step-by-step instructions to help you cultivate healthy lemongrass plants from seed.
Understanding Lemongrass Seeds
Lemongrass seeds are small, brown, and resemble wheat grains. They have a relatively low germination rate (around 20-30%), making it essential to sow multiple seeds to ensure success. Seeds are typically viable for 1-2 years when stored in a cool, dry place.
Step-by-Step Guide to Growing Lemongrass From Seed
1. Seed Preparation
Before sowing, lemongrass seeds benefit from pre-treatment to improve germination rates.
2. Soil and Container Selection
Lemongrass thrives in well-draining, fertile soil. Use a mix of potting soil, perlite, and compost for optimal growth.
Sow seeds in small pots or seed trays filled with soil, placing them 1-2 cm deep.
3. Germination Conditions
Lemongrass seeds require warmth and humidity to germinate.
Cover the seed tray with a clear plastic dome or plastic wrap to retain moisture. Germination typically takes 2-4 weeks.
4. Seedling Care
Once seedlings emerge, remove the plastic cover and provide adequate light.
5. Transplanting
Transplant seedlings into larger pots or the garden when they are 10-15 cm tall.
