Expert tips
The key tip
Cymbopogon flexuosus in cold climates is grown as an annual or in pots overwintered at 10-15°C. Harvest stems before flowering for optimal lemony flavor (young leaves).
The common mistake
Pruning too late (September) weakens the plant before winter, resulting in poor harvest the following year.
The pro's trick
Continuous harvesting of outer leaves maintains vigor and flavor: pinch without exhausting the heart of the plant.
Care
Exposure
Place lemongrass in full sun for optimal development. It tolerates shade poorly and requires at least 6 hours of direct sunlight daily. In cooler climates, choose the sunniest location possible to enhance its essential oils.
Watering
Water regularly during the growing season to keep the soil slightly moist, without waterlogging. In winter or dry periods, reduce watering. Lemongrass appreciates some root moisture but dreads stagnant excess humidity.
Soil and substrate
Well-draining, fertile, and slightly acidic soil is ideal. Prepare the substrate with quality potting soil enriched with organic matter. For container growing, use a mix for perennials or grasses, with a drainage layer at the bottom.
Fertilizer and nutrition
Apply balanced fertilizer in spring and early summer to support growth. Moderate applications are sufficient; excess promotes less aromatic foliage. Organic mulch will gradually enrich the soil.
Pruning and harvest
Regularly harvest outer leaves to encourage branching and density. In late winter or early spring, cut the clump back to 10-15 cm from the ground. This rejuvenates the plant and promotes vigorous new growth.
Diseases and pests
Lemongrass is generally hardy. Watch for spider mites indoors or in very dry climates. Excess humidity can promote root rot. Ensure good air circulation and avoid watering the foliage.
Did you know?
Lemongrass (Cymbopogon flexuosus) has been a staple of traditional Indian and Asian medicine for centuries. Its essential oils, rich in citral, give it not only its characteristic lemon aroma but also recognized properties in aromatherapy. It is indeed one of the world's most cultivated grasses for its culinary, cosmetic, and natural insect-repelling applications.
Where to buy it
Plant in spring or early autumn, avoiding spells of intense heat. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, April, May, September.
