  • Boil lemongrass leaves and use the infused water as a natural spray

4. Easy to Grow & Maintain

Lemongrass is low-maintenance, making it perfect for beginner gardeners. It thrives in warm climates but can also be grown in containers for easy overwintering in colder regions.

Growing Benefits:

  • Drought-resistant
  • Low maintenance
  • Grows quickly & produces year-round in warm climates
  • Can be grown in pots indoors or outdoors

How to Grow Lemongrass: Step-by-Step Guide

Lemongrass is a tropical plant, meaning it loves sun, warmth, and well-draining soil.

Whether you’re growing it from stalks, seeds, or transplants, follow these simple steps to ensure healthy growth.

1. Choosing the Right Lemongrass Variety

There are two common types of lemongrass:

  • Cymbopogon citratus – Best for culinary use (milder & tastier)
  • Cymbopogon flexuosus – Used mainly for essential oils

If you want edible lemongrass, go for Cymbopogon citratus!


2. Growing Lemongrass from Stalks (The Easiest Method!)

If you have fresh lemongrass stalks from a grocery store or market, you can propagate them in water.

Step-by-Step: Rooting Lemongrass in Water

  1. Buy fresh lemongrass stalks with intact bases
  2. Remove outer leaves & trim the tops
  3. Place stalks in a glass of water (covering the bottom 2 inches)
  4. Keep in a sunny window (6-8 hours of sunlight)
  5. Change the water every 2 days
  6. In 1-2 weeks, roots will start forming
  7. Once roots are at least 1 inch long, transplant into soil

3. Growing Lemongrass in Soil

Lemongrass grows best in warm, well-draining soil. If you’re planting directly in the garden, choose a sunny location.

Planting Instructions:

  • Soil: Light, well-draining soil (sandy or loamy)
  • Sunlight: Full sun (6-8 hours daily)
  • Watering: Keep soil slightly moist but not waterlogged
  • Temperature: Prefers 70°F+ (can tolerate 50°F but stops growing in cold)
  • Spacing: Plant 2-3 feet apart (they grow bushy!)

4. Growing Lemongrass in Containers

If you live in colder climates, you can grow lemongrass in pots and bring it indoors in winter.

Container Growing Tips:

  • Use a large pot (at least 12 inches deep & wide)
  •  Fill with well-draining potting mix
  • Keep in a sunny window or greenhouse in winter
  • Water once soil dries out slightly (but don’t overwater!)
  • Move back outside when temperatures are above 50°F

5. Caring for Your Lemongrass

Once your lemongrass is established, it’s very low maintenance. Here’s how to keep it thriving:

Watering – Water regularly, but avoid soggy soil
Fertilizing – Use a balanced fertilizer once a month during active growth
Pruning – Trim dead or dry leaves to keep the plant healthy
Dividing – Every 2-3 years, dig up and divide clumps to prevent overcrowding

Overwintering Tip: If you live in cold zones (below USDA Zone 9), bring your potted lemongrass indoors during winter. You can also cut it back and mulch heavily to protect the roots.


Harvesting & Storing Lemongrass

You can start harvesting lemongrass once it reaches 12 inches tall.

How to Harvest:

  • Use a sharp knife or shears to cut the thick stalks at the base
  • Leave at least 2 inches of the plant to keep it growing
  • Use fresh stalks immediately, or store them

How to Store Lemongrass:

  • Refrigerator – Store fresh stalks in a plastic bag (lasts up to 2 weeks)
  • Freezer – Chop stalks & freeze in airtight containers (lasts 6 months)
  • Drying – Hang stems to dry, then store in jars for teas & seasonings
