How to Grow Lemongrass

Lemongrass (Cymbopogon citratus) is a fragrant tropical grass valued for its citrus aroma, culinary uses, and ornamental appeal. It thrives in full sun, warm temperatures, and moist, well-drained soil. This guide explains planting, germination, care, harvesting, and climate considerations suitable for all regions.

Where Should You Plant Lemongrass?

  • Best location: Full sun; lemongrass produces the strongest stalks with ample light.
  • Soil: Moist, well-drained, fertile soil; pH 6.0–7.5.
  • Moisture: Consistent moisture supports vigorous growth; avoid waterlogging.

When Should You Plant Lemongrass?

  • Start indoors: Begin seeds or rooted stalks in warm conditions; lemongrass establishes quickly.
  • Transplanting: Move outdoors once temperatures remain warm and stable.
  • Direct planting: Suitable in consistently warm climates; plant when soil supports root development.

How Do You Plant Lemongrass?

  • Depth: Plant rooted stalks so the base sits just below the soil surface.
  • Spacing: Space plants 12–24 inches apart; lemongrass forms large clumps.
  • Quantity: One plant provides many stalks; multiple plants create a dense aromatic patch.

Which Plants Grow Well With Lemongrass?

  • Companions: Ginger, turmeric, basil, and other warm-season herbs.
  • Avoid: Plants requiring dry soil or heavy shade.
  • Best pairing: Moisture-loving herbs that thrive in similar conditions.

How Do You Water and Feed Lemongrass?

  • Watering: Keep soil evenly moist; lemongrass benefits from regular watering during hot seasons.
  • Feeding: Apply compost or a balanced organic fertilizer to support leaf and stalk production.

How Do You Care for Lemongrass?

  • Support: No staking required; plants form sturdy upright clumps.
  • Weeding: Maintain a clean planting area to reduce competition and preserve soil moisture.

Can You Grow Lemongrass in Containers?

  • Container size: Minimum 10–12 inches deep and wide; larger containers support long-term growth.
  • Winter growing: Grow indoors in warm, bright environments or under grow lights during cool seasons.

What Pests or Diseases Affect Lemongrass?

  • Pests: Aphids and spider mites; monitor foliage and use organic controls if needed.
  • Diseases: Root rot in overly wet conditions; ensure proper drainage and avoid overwatering.

How Do You Harvest Lemongrass?

  • Timing: Harvest stalks once they reach pencil thickness; flavor is strongest in mature stalk bases.
  • Leaves: Snip fresh leaves for tea or aromatic use.
  • Seeds: Lemongrass rarely produces viable seeds; propagation is typically done by division.
