Lemongrass, with its citrusy aroma and versatile culinary uses, is a popular herb that many home gardeners are eager to cultivate. But knowing how to plant lemongrass effectively can be a bit of a challenge, especially for beginners. This comprehensive guide will walk you through every step, from choosing the right variety to harvesting your own fragrant lemongrass.
Understanding Lemongrass: A Brief Overview
Lemongrass (Cymbopogon citratus) is a tropical perennial grass native to Southeast Asia. It’s known for its tall, slender stalks and its distinct lemony scent, which comes from the essential oil contained within the leaves. Lemongrass is a staple ingredient in Asian cuisine, used in soups, curries, and teas. It also has medicinal properties and is often used in aromatherapy.
Choosing the Right Lemongrass Variety
Several lemongrass varieties are available, each with slightly different characteristics. Here are two popular options:
- Citronella Lemongrass: This variety is known for its strong citronella scent, making it a natural mosquito repellent.
- East Indian Lemongrass: This variety is preferred for culinary uses due to its milder flavor and aroma.
When and Where to Plant Lemongrass
Timing is Key
The best time to plant lemongrass is during the warm months, when the soil temperature is consistently above 60°F (15°C). In most regions, this means planting in spring or early summer. However, if you live in a tropical or subtropical climate, you can plant lemongrass year-round.
Location, Location, Location
Lemongrass thrives in full sun to partial shade. It prefers well-drained soil that is rich in organic matter. If your soil is heavy clay, amend it with compost or sand to improve drainage.
Planting Lemongrass: A Step-by-Step Guide
Starting from Seed
While it’s possible to start lemongrass from seed, it’s a challenging process. Seeds can be slow to germinate, and the seedlings are often weak. If you choose this method, be patient and provide consistent care.
1. Sow seeds indoors: Start seeds indoors 6-8 weeks before the last frost. Use a seed starting mix and sow seeds ¼ inch deep.
2. Maintain warmth and moisture: Keep the soil consistently moist and provide a warm temperature of around 75°F (24°C).
3. Thin seedlings: Once seedlings have a few true leaves, thin them to the strongest plant.
4. Hardening off: Before transplanting outdoors, gradually acclimate seedlings to outdoor conditions by placing them in a sheltered location for a few hours each day.
Starting from Division
The easiest way to propagate lemongrass is by dividing established clumps. This method is quick and reliable, producing healthy plants that will quickly establish themselves.
1. Select a healthy clump: Choose a healthy, well-established lemongrass clump that has multiple shoots.
2. Divide the clump: Carefully divide the clump into smaller sections, ensuring each section has at least one healthy shoot and some roots.
3. Plant the divisions: Plant the divisions in individual pots or directly in the ground, spacing them 1-2 feet apart.
Starting from Cuttings
Another way to propagate lemongrass is by taking cuttings from mature plants. This method is relatively easy and produces new plants quickly.
1. Take cuttings: Cut 6-8 inch lengths of healthy stems from a mature plant, ensuring each cutting has at least one node (where roots will form).
2. Remove leaves: Remove the leaves from the bottom 2-3 inches of the cutting.
3. Dip in rooting hormone: Dip the cut end of the cutting in rooting hormone to encourage root growth.
4. Plant in rooting medium: Plant the cuttings in a pot filled with a rooting medium, such as perlite or vermiculite.
5. Keep moist: Keep the rooting medium consistently moist, but not waterlogged.
6. Place in a warm location: Place the pot in a warm, bright location, but out of direct sunlight.
7. Transplant when roots form: Once cuttings have developed roots, usually within 4-6 weeks, transplant them into individual pots or directly into the ground.
Caring for Lemongrass
Watering
Lemongrass prefers moist soil, but it’s also susceptible to root rot if the soil is waterlogged. Water deeply and thoroughly, allowing the soil to dry out slightly between waterings.
Fertilizing
Lemongrass benefits from regular fertilization, especially during the growing season. Use a balanced fertilizer, such as a 10-10-10 formula, every 4-6 weeks.
Mulching
Mulching around lemongrass plants helps retain moisture, suppress weeds, and moderate soil temperature. Use organic mulch, such as shredded bark or compost.
Harvesting
Lemongrass can be harvested throughout the growing season. You can harvest the entire stalk or just the lower portion of the stalk, where the flavor is most concentrated.
Winterizing Lemongrass
Lemongrass is a tropical plant that is not cold-hardy. In colder climates, you’ll need to protect it during the winter months.
Bring plants indoors: If you live in a region with cold winters, bring your lemongrass plants indoors before the first frost. Place them in a sunny location and continue to water them regularly.
Cut back plants: If you’re growing lemongrass outdoors, cut back the plants to about 6 inches tall before the first frost. This will help protect the plant from winter damage.
Mulch heavily: Apply a thick layer of mulch around the base of the plants to help insulate the roots.
Lemongrass: Beyond the Garden
