How to Grow Lemongrass: A Beginner’s Guide


Lemongrass is a delicious and versatile herb that’s easy to grow at home. It’s a great addition to any garden, and it can be used in a variety of dishes.

Growing Lemongrass

There are two main ways to grow lemongrass: from seed or from a supermarket stalk.

Growing Lemongrass from Seed

  • Sow seeds in spring in moist compost.
  • Keep the pot covered in a warm place to aid germination.
  • When the seedlings are large enough to handle, transplant them into larger pots.
  • Once the roots are showing through the bottom, transplant into a larger pot.

Growing Lemongrass from a Stalk

  • Take a whole lemongrass stalk and slice off a sliver from the base.
  • Remove any leaves and place the stalk in a glass of water.
  • Put it in a warm, sunny spot and refresh the water every day.
  • It should take a couple of weeks for roots to appear.
  • Plant the rooted stalk in a pot of compost.

Caring for Lemongrass

  • Lemongrass prefers well-drained soil and plenty of sunlight.
  • Water regularly, especially during hot weather.
  • Fertilize monthly with a balanced fertilizer.
  • Cut back the stems to 10cm in fall.

Harvesting Lemongrass

  • Once your lemongrass plant is mature, you can start harvesting the stems.
  • Cut stems just below the base, leaving plenty on the plant to allow it to produce new growth.


  • Brown, red, or yellow marks on leaves could be lemongrass rust. Keep the plant healthy with regular watering and avoid watering from above.
  • Yellow or brown spots on leaves could be a sign of the yellow sugarcane aphid. Wash the aphids off the lemongrass with water.


Growing lemongrass is a rewarding experience. With a little care and attention, you can enjoy fresh, homegrown lemongrass all season long.
