Why Grow Lemon Grass?
I planted my first lemon grass clump on a whim, after tasting an incredible Thai soup prepared by a friend. One slurp of that vibrant broth, infused generously with fresh stalks, and I knew I had to cultivate my own source.
Lemon grass (Cymbopogon citratus) grows quickly, tastes amazing, and lends a citrusy sparkle to an otherwise average garden plot. If you've savored its aromatic touch in cooking, you'll find growing lemon grass at home deeply satisfying and straightforward.
Selecting and Preparing Lemon Grass for Planting
Start by grabbing a few fresh lemon grass stalks from your local farmer’s market or organic grocery store. Check to ensure stalks feel firm and fresh, the bases still intact.
Once home, trim the stalks to about 6 inches (15 cm) in length and remove all dead outer leaves. Place the stalks upright in a jar of water, allowing the lower half to submerge fully.
Within a week or two, white roots appear—this is your cue to pot them up.
Ideal Growing Conditions
Location Matters
Lemon grass thrives in full sun—think at least 6 to 8 hours of direct sunlight daily. Find the warmest, sunniest corner of your garden or balcony for best performance.
This plant loves heat; below 40°F (4°C), growth halts, and frost (below 32°F or 0°C) kills it outright. For those facing colder climates, planting in containers works wonders—just move your pots indoors around wintertime.
Soil Selection and Preparation
The easiest part about growing lemon grass—the soil isn't picky. Choose loose, loamy soil with excellent drainage.
I typically blend organic compost or worm castings into potting mix, giving lemon grass a nutrient-rich environment. Slightly acidic to neutral soil (pH level 6.0–7.0) helps the plant thrive, says the University of Florida Extension.
Planting and Care: Simple Steps to Flourishing Lemon Grass
- Transplant gently: After roots reach about 2 inches (5 cm), plant individual stalks 2 feet (60 cm) apart and an inch (2.5 cm) below soil level. Water thoroughly.
- Water routines: Lemon grass prefers soil consistently moist but never soggy. Keep an eye—you want lightly damp soil, watering whenever the top layer dries out.
- Feeding the growth: Every six weeks, feed with a balanced, organic fertilizer—preferably one low in phosphorus to encourage lush foliage rather than blooms.
- Pruning and harvesting: Once your lemon grass reaches a height of 12 to 24 inches (30–60 cm), harvesting fragrant stalks becomes easy. Snap off the outer stalks at ground level, preserving the inner growth.
According to the Clemson Cooperative Extension, regularly pruning your lemon grass keeps it tidy and stimulates healthy regrowth, ensuring a continuous supply year-round.
Common Challenges and Solutions
Watch Out for Pests
In my experience, lemon grass rarely attracts troublemakers—but aphids occasionally show interest. A simple stream of water or diluted neem oil spray sends these pests packing swiftly and effectively.
Preventing Diseases
Overwatering invites fungal diseases—particularly root rot. Keeping soil drainage sharp ensures these issues never visit your garden.
If planting in pots, choose ones with plenty of drainage holes and lay down gravel at the bottom for extra protection.
Expanding Your Lemon Grass Adventure
Once you've successfully grown this fragrant grass, propagation becomes addictive. Mature lemon grass crowns can be lifted and divided every few years—expanding your crop or gifting to gardening pals.
After all, the pleasure of cooking with your homegrown aromatic herbs multiplies immensely when shared around a great meal with good friends.
Common Questions About Growing Lemon Grass
What soil conditions coax lemon grass into thriving?
Lemon grass favors loamy, well-draining soils with a good dose of organic matter. To persuade vigorous growth, enrich your planting spot with compost or aged manure and sustain slight moisture without sogginess.
How often does lemon grass crave watering?
Regular hydration speaks volumes to lemon grass, especially during warm weather. Allow the soil surface to dry between watering sessions, watering deeply twice a week generally satisfies its thirst.
Can lemon grass withstand chilly climates outdoors?
Lemon grass tolerates warmth far better than cold. If you reside where frost bites deep, consider cultivating lemon grass in movable pots or containers. When temperatures dip, simply relocate your aromatic greenery indoors for safety.
What's the best way to propagate lemon grass?
Propagation unfolds naturally through division or stalks rooted in water. Snip sturdy stalks, place them into water-filled jars until roots emerge, then transplant them into rich, airy garden soil with ample sunlight.
Does lemon grass require special fertilization?
Nitrogen-rich organic fertilizers, such as diluted fish emulsion or compost tea, deliver optimal nourishment to lemon grass. Feed lightly every few weeks to inspire lush, aromatic growth.
Are pests particularly drawn to lemon grass?
Lemon grass repels more pests than it invites, yet occasional visits from aphids or spider mites might occur. Combat these invasions effectively with gentle insecticidal soap sprays or neem oil treatments.
When and how should lemon grass harvesting begin?
Harvesting begins once stalks reach about 12 inches tall and at least half an inch thick. Slice stalks cleanly at the base, leaving the root crown unharmed for continuous growth and subsequent harvests.
Growing Lemon Grass rewards patience and a little grit. Start with rich soil, keep the roots damp but never soggy, and don’t let the stalks get crowded—lemongrass hates a traffic jam. Plenty of sun keeps those blades sharp and fragrant, while regular trimming gives you fresh supply for the kitchen and encourages bushier growth. Watch for pests, but don’t lose sleep—this hardy plant usually shrugs off trouble.
If you’ve mastered growing lemon grass, consider adding more variety to your herb patch—try your hand at growing thyme or a punchy row of dill. Nothing beats the satisfaction of snipping your own herbs, straight from the source. Good soil, sun, and patience: that’s the real recipe.
The Homesteader's Guide to Lemon Grass Self-Sufficiency

- Long-Term Storage: Bundle harvested stalks, wrap in parchment paper, and refrigerate for freshness lasting up to 2 weeks.
- Efficient Drying: Air-dry leaves in shaded area at 70–90°F (21–32°C) until crisp; store in airtight containers for cooking or tea blends.
Propagation for Sustainability
- Root Division Method: Divide lemon grass clumps annually to expand your garden without buying new plants.
- Water Propagation: Soak stalk bases in water until roots emerge (usually 2–3 weeks), then transplant directly into garden soil.
Useful Productivity Stats
- One mature lemon grass plant provides enough stalks for weekly culinary use for an average family throughout the growing season.
- A single clump of lemon grass planted in optimal conditions expands to approximately 3 feet (90 cm) wide in one year.
