Growing lemongrass from seeds is easy and requires minimal effort. 

  1. Fill a seed tray with a moistened, well-draining medium mixture of equal parts compost, cocopeat, or coconut fiber fine.
  2. Sow lemongrass seeds 1 inch apart and 1/4 inch deep. Cover with a layer of the medium.

Requirements for Growing Lemongrass from Seeds

How to Grow Lemongrass from Seed 2


Lemongrass needs a minimum of 7-8 hours of bright, direct sunlight to grow well. Plants grown in the shade will show unhealthy growth and are prone to pests and diseases.


For best growth, use fertile, well-drained soil with a pH of 6.5-7. Rich, loamy soil amended with a handful of aged manure will provide all the essential nutrients.


The tender seedlings need considerably moist soil to grow well. However, as the plant matures, it can tolerate short periods of drought. The best option is to water the plant whenever the top inch feels dry to touch.

Temperature & Humidity

Lemongrass thrives in warm, humid climates and needs a temperature range of 68-86 F or 20-30 C. The plant can take hotter climates but is not resistant to temperatures below 50 F or 10 C.

Also, the plant needs 70-80% humidity to grow well. Keep a humidifier handy for drier days.

Lemongrass Plant Care



The plant loves an occasional nitrogen boost for lusher leaf growth. You can also add a layer of aged manure, well-rotten cow dung, or manure tea at the onset of its growing season.


Snip the overgrown shoots to maintain the desired shape of the plant. Also, remove the dead and dried leaves after the winter.

Pests and Diseases

Lemongrass is prone to diseases like Leaf Blight, Leaf Spot, and Rust that can be dealt with by spraying insecticidal neem solution on the plant.

Keep the plant in full sunlight and avoid overwatering to keep potential diseases at bay.
