Lemongrass Plant Care

Lemongrass (Cymbopogon citratus) belongs to the Poaceae family within the Cymbopogon genus. Lemongrass is native to Maritime Southeast Asia. Lemongrass is also known as Cochin Lemongrass, West Indian Lemongrass, Lemon Grass.

Lemongrass displays a clumping, upright growth habit, reaching up to 3 inches tall with a spread of approximately 2 inches. Lemongrass produces greenish to yellow flowers on elongated, slender stalks.

Leaf size: approximately 1 inches.

Cymbopogon citratus requires watering every 3–7 days. Allow the top layer of soil to dry between waterings to prevent root rot. Reduce watering frequency during winter when growth slows.

Lemongrass thrives in full sun light conditions. The optimal light range is 2000–5000 lux. Avoid placing Lemongrass in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Cymbopogon citratus grows best at temperatures between 60°F and 90°F. Lemongrass prefers humidity levels of 50–70%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Well-draining soil mix. Good drainage is essential for Lemongrass to prevent waterlogging, which leads to root rot and fungal issues.

Repot every 1-2 years in early spring. Choose a pot one size larger than the current container, and ensure it has drainage holes to allow excess water to escape.

Lemongrass can be propagated through division or stem cuttings.

Lemongrass is susceptible to aphids, grasshoppers, spider mites. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Lemongrass grows outdoors in USDA Zone 9b – 12b. Native to Maritime Southeast Asia, Lemongrass is adapted to warm climates. In cooler regions, grow Lemongrass as a houseplant or bring it indoors before the first frost.
