I’ve grown lemongrass for over five years, and honestly, it’s one of the easiest and most rewarding herbs to cultivate. Whether you’re cooking Thai curries, brewing calming teas, or just love the fresh scent, growing your own lemongrass beats store-bought every time.
Preferences vary—some gardeners want towering clumps for privacy screens, others just need a few stalks for cooking. I started small, with a single stalk from the grocery store, and now I have a thriving patch that feeds my kitchen and my soul. If you’ve ever wondered how to grow lemongrass successfully, you’re in the right place.
In this guide, I’ll share everything I’ve learned—from planting tips to harvest tricks—so you can grow lemongrass with confidence. No fancy tools or greenhouse required. Just sunlight, water, and a little patience.
By the end, you’ll know exactly how to grow lemongrass that’s fragrant, flavorful, and ready when you need it. Let’s dig in.
Why I Love Growing Lemongrass (And You Will Too)
Lemongrass isn’t just a kitchen staple—it’s a garden workhorse. In my experience, it repels mosquitoes naturally, adds texture to garden beds, and grows like a weed once established. Plus, the entire plant is useful: stalks for cooking, leaves for tea, and even the roots for propagation.
I first tried growing lemongrass from a store-bought stalk placed in a glass of water. Within days, roots sprouted. In weeks, green shoots emerged. That’s when I knew this plant was special. It’s forgiving, fast-growing, and thrives in warm climates—but even cooler zones can grow it in containers.
Whether you’re in Florida, California, or somewhere in between, lemongrass adapts well. It loves full sun and well-drained soil, and once it takes off, it’ll reward you with lush, grassy clumps that smell like a tropical breeze.
How to Grow Lemongrass: Step-by-Step from My Garden
Starting from Stalks (My Favorite Method)
The easiest way I’ve found to grow lemongrass is from fresh stalks. Buy organic lemongrass from the grocery store—look for firm, green bases with no mold. Trim the tops, leaving about 4–5 inches of stalk, then place the base in a glass of water.
Change the water every 2–3 days. In 1–2 weeks, white roots will form. Once they’re 1–2 inches long, plant the stalk in a pot or garden bed with rich, well-draining soil. Keep it moist but not soggy.
Pro tip: I plant mine in a sunny corner of my herb garden, spacing them 12–18 inches apart. They grow into dense clumps, so give them room to breathe.
Growing from Seed (For the Patient Gardener)
If you’re up for a challenge, lemongrass seeds are available online. They’re slow to germinate—often taking 2–3 weeks—and need warmth (75–85°F) to sprout.
I sow seeds in seed trays with a light potting mix, keeping them under grow lights. Once seedlings have a few true leaves, I transplant them outdoors after the last frost. It’s slower than stalk propagation, but rewarding if you love the full journey.
Container Growing: Perfect for Small Spaces
Don’t have a yard? No problem. I grow lemongrass in 12-inch pots on my patio. Use a large container with drainage holes and fill it with a mix of potting soil and compost.
Containers dry out faster, so I water mine every 2–3 days in summer. In winter, I move the pots indoors near a sunny window. Lemongrass hates cold, so protect it below 50°F.
Lemongrass Care: What I’ve Learned Over the Years
Sunlight and Soil
Lemongrass craves sun—at least 6 hours of direct light daily. In my garden, I plant it where tomatoes and peppers grow, and it thrives alongside them.
Soil should be loose and fertile. I mix in compost and a bit of sand to improve drainage. Lemongrass hates “wet feet,” so avoid heavy clay or waterlogged spots.
Watering and Feeding
Keep the soil consistently moist, especially during dry spells. I water deeply once or twice a week, depending on the weather. Mulching with straw helps retain moisture and suppress weeds.
Every 4–6 weeks, I feed my lemongrass with a balanced organic fertilizer or compost tea. It responds well to nitrogen, which keeps the leaves lush and green.
Pruning and Maintenance
I harvest outer stalks regularly to encourage new growth. Cut stalks at the base with a sharp knife—don’t pull, or you might damage the clump.
In late fall, I trim the tops back by one-third to tidy the plant and prevent it from becoming too woody. In colder regions, I cut it back to the ground and mulch heavily for winter protection.
Harvesting Lemongrass: When and How
You can start harvesting lemongrass about 4–6 months after planting. Look for stalks that are at least ½ inch thick—these are mature enough to use.
I harvest in the morning when the plant is full of moisture. Cut stalks close to the soil, leaving the inner core to regrow. Each clump can produce multiple harvests per year.
Store fresh stalks in the fridge for up to 2 weeks, or freeze them for longer storage. I also dry the leaves for tea—just hang them in a cool, dry place.
Common Problems and How I Fix Them
Yellowing leaves? Usually a sign of overwatering or poor drainage. I check the soil and reduce watering if needed.
Pests like aphids or spider mites can appear, especially indoors. I spray with a mild soap solution or introduce ladybugs to my garden.
In cold climates, lemongrass may die back in winter. I treat it as a perennial by mulching heavily or bringing containers indoors.
Key Takeaways
- Grow lemongrass easily from store-bought stalks in water—no seeds needed.
- Plant in full sun with well-drained, fertile soil for best results.
- Water regularly but avoid soggy soil; containers need extra attention.
- Harvest outer stalks when they’re at least ½ inch thick.
- Protect from frost—bring potted plants indoors in winter.
FAQ: Your Lemongrass Questions Answered
Can I grow lemongrass indoors?
Yes! I grow mine in large pots near a south-facing window. Just ensure it gets 6+ hours of sunlight and keep the soil moist.
How long does it take to grow lemongrass from a stalk?
Roots appear in 1–2 weeks. You can harvest usable stalks in 4–6 months, depending on growing conditions.

Not really. It spreads slowly via clumps, not runners. I contain mine in pots or bordered garden beds to keep it tidy.
Final Thoughts: Grow Lemongrass and Taste the Difference
Growing lemongrass has transformed my cooking and my garden. There’s something deeply satisfying about snipping a fresh stalk, crushing it, and releasing that citrusy aroma right before adding it to a curry or tea.
