Let’s get into the nittyn gritty of how to grow lemongrass from scratch, with real world tips, a personal story, and science backed info along the way.

What is Lemongrass?

Lemongrass (Cymbopogon citratus) is a tropical grass native to Southeast Asia. It’s famous for its aromatic lemon scent and flavor, which comes from citral, the main essential oil in the plant. This fast growing herb can reach up to 3–5 feet tall in ideal conditions and loves warmth, sun, and moisture.

There are over 50 species of lemongrass, but two main types are grown at home:

• East Indian Lemongrass (Cymbopogon flexuosus) – Commonly used in perfumes and soaps.
• West Indian Lemongrass (Cymbopogon citratus) – Preferred for cooking and herbal teas.

Why Grow Lemongrass at Home?

1. It’s practically foolproof

Even if you’ve killed every houseplant you’ve ever owned, lemongrass gives you a second chance. It grows well in pots or garden beds and bounces back with minimal care.

2. Culinary goodness

Fresh lemongrass elevates dishes like Thai curry, Tom Yum soup, and marinades. You can’t beat the flavor of home harvested stalks.

3. Mosquito repellent

Citronella, found in lemongrass, is a natural mosquito deterrent. It won’t completely eliminate them, but it definitely helps.

4. Herbal tea on tap

Fresh lemongrass tea is calming and supports digestion. A handful of leaves, some boiling water, and you’ve got a spa in a cup.

Real Life: How I Accidentally Became a Lemongrass Gardener

Back in 2020, during the lockdown, I was desperate for a new hobby. I grabbed a few lemongrass stalks from the local market—not to grow, but to cook! I used two in a curry, and on a whim, stuck the leftovers in a jar of water on my windowsill.

A week later, roots appeared.

Three years later, that same plant has become a thriving, waist high cluster that’s been split and shared with half my neighborhood.

How to Grow Lemongrass: What Does Lemongrass Need to Grow?

Lemongrass is low maintenance, but it does have a few preferences:

Step 1: How to Grow Lemongrass: Choose Your Lemongrass Type

Because even a fragrant herb like lemongrass has its own personality.

Let me tell you something I wish someone had told me when I first started gardening: not all lemongrass is the same. Seems obvious in hindsight, but back when I was just getting into herbal gardening, I didn’t even know there were different kinds. Lemongrass was lemongrass. Period.

Turns out, I was wrong. And that one small detail knowing the right type to grow , can shape how useful, flavorful, or even fragrant your plant turns out to be.

Meet the Two Main Types

So, here’s what I learned through trial, error, and a lot of digging around :

1. West Indian Lemongrass (Cymbopogon citratus) – The Kitchen Hero

If you’ve ever had a Thai soup with that clean citrus zing, chances are, this was the lemongrass behind it. West Indian lemongrass is the kind you want if you’re into cooking, brewing herbal tea, or just enjoy having a soft, lemony scent drift across your garden.

What makes it great?

• Flavor: Mild, sweet citrus notes, not overpowering.
• Texture: The base is tender enough to chop into meals when young.
• Scent: Clean and calming, not sharp or medicinal.
• Use: Best for culinary purposes, teas, and home remedies.

2. East Indian Lemongrass (Cymbopogon flexuosus) – The Oil Queen

This one is mostly grown for essential oils, soaps, candles, and anything that belongs in a spa. It has a more intense aroma, and while you can cook with it, the flavor isn’t quite as pleasant, more medicinal and grassy.

Why choose this type?

• High citral content: Perfect for distilling oils.
• Aroma: Stronger, deeper, more pungent.
• Use: Excellent for DIY bug sprays, perfumes, and potpourri.

Step 2: How to Grow Lemongrass: Find the Perfect Spot

Here’s the thing about lemongrass—it’s not a fussy plant, but it does have its preferences. If lemongrass were a person, it would be the type that books tropical holidays in the middle of winter and refuses to leave the beach. That’s how much it loves the sun.

The Golden Rule: Sun, Sun, and More Sun

Lemongrass needs at least 6 to 8 hours of direct sunlight every day. Not filtered light, not dappled shade, full sun. The more sun it gets, the taller and fatter those grassy stalks grow. Sunlight fuels its signature lemony oils, too. Ever noticed how lemongrass smells stronger in the heat? That’s no accident, heat and sun crank up the essential oil production inside the leaves and stems (Source: University of Florida IFAS Extension).

If you’re planting it outside, south facing gardens are usually a good bet. Avoid shaded corners or spots blocked by walls or fences. Lemongrass will grow in partial shade, but you’ll likely end up with weak, skinny stalks that just won’t cut it in your Thai curry.

Frost? Forget It

Now, if you live somewhere that gets frosty in winter (looking at you, USDA Zone 8 and below), lemongrass won’t survive outdoors once the temperatures dip below 40°F (4°C). It’s a tropical grass, native to Southeast Asia and parts of India, and that means it thrives in warmth. Even a light frost can damage it beyond repair.

If you’re up north, you’ve got two options:

• Option 1: Grow lemongrass in a pot that you can move indoors during the cold months.
• Option 2: Treat it like an annual and start fresh every spring. Just don’t expect it to bounce back from a snowy backyard.

Real Life Note: My cousin Jenna in Vermont grows lemongrass in large terracotta pots. She drags them into her sunroom every October like clockwork. “It’s a bit of a workout,” she told me, “but it’s worth it for fresh lemongrass tea all winter.” She places it near a sunny window, waters sparingly, and it pretty much goes dormant until spring.

Soil Matters Too

Even if you’ve got the perfect sunny corner, don’t forget that soil plays a role too, but we’ll dig into that in the next step. For now, just focus on finding a spot with plenty of sun, warmth, and shelter from harsh winds.

Quick Checklist:

• Protect from cold drafts or wind

• At least 6–8 hours of direct sunlight daily

• No frost exposure—bring indoors if needed

• Indoors? Choose a south facing window

Step 3: How to Grow Lemongrass: Prep the Soil

Let’s get one thing straight: lemongrass might look like a low maintenance plant, but when it comes to soil, it’s got standards. If your soil is heavy, soggy, or lifeless, lemongrass is going to sulk. You won’t get those thick, juicy stalks that make it so popular in curries and teas.

Think of the soil like the mattress your plant sleeps on. Too hard? It gets stressed. Too soggy? Root rot. Just right? Growth party .

What Kind of Soil Does Lemongrass Like?

1. Well Draining Is Non Negotiable

Lemongrass hates waterlogged soil. It’s not a swamp plant, it likes moisture, sure, but it doesn’t want to sit in a puddle. If you’re planting it in the ground, make sure the soil drains well after watering. Standing water = root rot = dead lemongrass.

If your soil is clay heavy which is common in many gardens, amend it with sand, compost, or aged manure. That helps loosen things up and improves drainage.

Real life story: My friend Naeem in Chittagong tried growing lemongrass directly in his backyard garden, but it was heavy clay. He said, “It looked fine for two weeks and then just turned yellow.” Once he mixed in compost and a bit of river sand, the new planting took off. Moral of the story? Don’t underestimate bad drainage.

2. Slightly Acidic to Neutral pH (6.0–7.5)

Lemongrass prefers soil that’s slightly acidic to neutral, ideally between 6.0 and 7.5 pH. You don’t need a fancy lab test, but if you’ve got a pH meter or test strip , easily found at garden centers or online, use it. If your soil is too alkaline, you can bring the pH down with peat moss or sulfur. If it’s too acidic, add some wood ash or lime to balance it.

Enrich the Soil: Feed It Right

Plain dirt is a good start, but enriched soil is where things really shine. Lemongrass loves a bit of pampering:

• Compost: Homemade compost or well rotted organic compost adds structure and nutrients.
• Organic matter: Coconut husk, leaf mulch, or aged cow dung helps keep the soil loose and alive.
• Worm castings: If you can find them, worm castings add a microbial punch that helps roots absorb nutrients better.

Adding these to the soil 2–3 weeks before planting gives time for the microbes to get active and the soil to “settle.” It’s like preheating the oven before baking.

Fact Check: According to the University of Illinois Extension, adding compost not only improves drainage and aeration but also boosts beneficial microbial activity especially helpful for herbs like lemongrass that are grown for their oils and flavor .

Step 4: How to Grow Lemongrass: Planting Lemongrass

You’ve got your spot. The soil’s ready. Now it’s time for the fun part: actually planting the lemongrass. This step can feel a bit like gardening meets kitchen magic. Whether you start with seeds, stalks, or ready made nursery plants, lemongrass is surprisingly forgiving just give it some attention, warmth, and room to stretch.

Option 1: Growing from Seeds for the Patient Gardener

Let’s be honest, growing lemongrass from seed isn’t for the impatient. Seeds take time to germinate about 14–21 days, and they’re a bit slow to start. But the upside? You get loads of plants for the price of one packet.

How to do it:

• Start seeds indoors about 6–8 weeks before your last expected frost.
• Use seed starting mix in trays or small pots.
• Keep the temperature around 70–75°F (21–24°C).
• Mist lightly and cover with plastic wrap until germination.
• Once the seedlings have at least 2–3 inches of growth and the weather is warm, transplant them outdoors.

Tip from an urban gardener :

“I started my seeds on a sunny windowsill in March. They looked like wispy grass for weeks, but by June, they took off like crazy. It was slow at first, but worth the wait”

Option 2: Propagating from Stalks : The No Fuss Method

This one’s for the grocery store adventurers. Next time you pick up lemongrass for a stir fry, save a few extra stalks. If they’ve got a bit of a bulb at the base and aren’t too dried out, you can root them at home.

Here’s how:

1. Choose 3–5 fresh stalks with a thick base.
2. Trim the top leafy parts off, leaving about 6 inches.
3. Place the base in a glass of clean water near a sunny window.
4. Change the water every 2–3 days.
5. In about a week, roots – tiny white threads will appear.
6. Once the roots are 2 inches long, transplant into well draining soil outdoors or in pots.

Real life win:

“I rooted lemongrass from my local Asian grocery store. It sat on my windowsill in a mason jar for two weeks. Once it hit the garden, it exploded. Who knew kitchen scraps could be so productive?” Rina, Portland,

Option 3: Buying Nursery Plants

If you’re just not into playing the waiting game, go for nursery plants. These are already established and ready to thrive. Just pop them in the ground or a large container once the risk of frost has passed.

Spacing Matters: Avoid the Jungle

Lemongrass might look like a clump of grass now, but give it time, it can reach up to 4–6 feet tall and 3 feet wide if it’s happy. Keep about 24 inches (2 feet) between each plant to allow proper air circulation and root spread.

Crowded plants aren’t just messy, they’re more likely to develop fungal issues, especially in humid climates.

A Backyard Story

My friend Sara, who lives in a warm zone in Texas, planted five lemongrass stalks about a foot apart thinking they’d “fill in” her herb bed. Within three months, her little patch looked like a scene from The Jungle Book. The lemongrass choked out her basil and tried climbing the fence. Moral of the story? Respect the space. These plants grow fast and wide. plant. Lemongrass grows bushy, and you don’t want it turning your garden into a jungle.

Step 5: Watering – Keep It Moist, Not Mushy

Lemongrass drinks water like it’s prepping for a marathon. Water frequently, especially during the hot months, but avoid waterlogging. A soggy lemongrass plant is a sad lemongrass plant. Mulching around the base can help retain moisture while preventing weeds.

Step 6: Feed Me, Seymour

Let’s talk straight. Lemongrass might look like a laid back kind of plant, but don’t be fooled, it loves its food. If you want thick, flavorful stalks that actually taste like lemongrass and not just green grass, you’ll need to feed it regularly.

I learned this the hard way.

A couple of years ago, I planted a row of lemongrass in a sunny corner of my backyard. The first few weeks, it grew fast, just like the seed packet promised. Then it slowed down. Leaves turned a little pale, and the stalks looked thin and sad. I thought it was just the heat. Turns out, I’d been skipping the most important step: feeding.

Once I started feeding it the right way, it perked up fast, thicker stalks, greener leaves, and that strong lemony smell I’d been missing.

What Lemongrass Really Wants

Lemongrass is a leafy herb, and that means it craves nitrogen. Nitrogen helps plants grow lush and green. Without it, they look weak, yellowish, and just… tired.

Here’s what I now use to feed my lemongrass:

• Compost: I add a handful around the base every 6 weeks.
• Fish emulsion: This stuff stinks, but plants love it. I dilute it in water and pour it right onto the soil.
• Compost tea: If you’ve got some old compost sitting around, soak it in water overnight. Use that liquid to water the plant, it’s like giving it a natural energy drink.
• Banana peel water : Chop up a banana peel, soak it in water for 2 days, and pour the water onto your lemongrass. It’s not magic, but it does help, especially during the summer.

How Often Should You Feed?

Here’s a simple rule:
Feed lemongrass every 6 to 8 weeks during the growing season spring through early fall . That’s it. No complicated schedule.

If you’re planting in spring, mix a bit of slow release organic fertilizer into the soil when you first transplant. Then just keep up with your compost or fish emulsion feedings every month or two.

My Backyard Mistake

I once skipped feeding for almost 3 months. The lemongrass kept growing, but it lost all its flavor. When I finally cut a stalk for tea, it tasted like hot water with a hint of grass. No citrus. No punch.

Lesson learned: if you don’t feed lemongrass, it might still grow, but it won’t taste the way it should. And let’s be honest, what’s the point of growing lemongrass if it doesn’t have that strong, zesty smell and flavor?

A Few Simple Tips

• Mulch helps. If you add a layer of mulch around the plant, it keeps the soil moist and slowly breaks down to feed the roots.
• Don’t overdo it. A little food often is better than dumping a ton at once.
• Avoid chemical fertilizers if you can. Lemongrass is easygoing, and it doesn’t need anything fancy.

Quick Feeding Guide:

Step 7: Pruning – Trim for Zen and Flavor

Lemongrass grows fast, and if you don’t keep an eye on it, it can get wild pretty quick. Think of pruning like giving your plant a little haircut, nothing fancy, just a quick tidy up to keep it healthy and happy.

Why Prune at All?

If you let lemongrass go without trimming, a few things happen:

• Old, dry leaves hang around and make the plant look scruffy.
• The middle gets crowded, blocking air and sunlight.
• It can spread out and take over more space than you want.

Cutting back encourages the plant to put energy into fresh, strong growth and that means tastier stalks and a nicer smelling plant.

When and How to Prune

• Snip off any yellow or brown leaves whenever you spot them.
• When harvesting, cut the stalks near the base but leave a bit so the plant can regrow.
• Once a year, usually in early spring, you can chop the whole clump back to about 4 to 6 inches above the ground. It might look bare, but trust me, it’ll bounce back.

A Quick Story

My friend Jamal ignored his lemongrass for a whole season. By fall, it looked scraggly, and the stalks were thin. After a good prune and clearing out dead bits, the lemongrass came back thicker and greener the next spring.

His takeaway?

“Sometimes plants just need a reset.”

A Few Simple Tips

After pruning, give it some water and maybe a bit of compost.

Use sharp scissors or garden shears so you don’t crush the stalks.

Don’t cut the plant down to the dirt—leave a little green so it can grow.

Step 8: Pest & Disease Control

Lemongrass is one of those plants that mostly minds its own business and doesn’t demand much. In fact, it kind of keeps other troublemakers at bay. I remember when I planted a few clumps near my porch, the mosquitoes that used to love that area suddenly disappeared. I didn’t even plan it that way. The smell alone sends them running.

That’s one of the nicest perks of lemongrass. Its strong lemony aroma is more than pleasant, it acts like a natural bodyguard against common pests like mosquitoes, aphids, and even whiteflies. That being said, lemongrass isn’t bulletproof. I found that out the hard way one rainy season.

The First Sign of Trouble

It started with the tips of the leaves turning brown. At first, I thought maybe the sun had scorched them. But then I flipped a leaf over and saw these dusty, orange like patches , classic signs of rust. Another time, it was leaf blight, with ugly brown streaks crawling across the blades. Both are fungal diseases, and both are pretty sneaky if you’re not paying attention.

Fungi love wet, crowded conditions. So if your lemongrass is too bunched up or the leaves stay damp too long, they’ll invite all the wrong guests.

How I Keep It in Check

1. Space and Airflow:
   I started giving each lemongrass clump a bit more breathing room. At least 2 feet apart. It feels like a small thing, but airflow really matters. Crowding is a recipe for fungus.
2. Morning Watering Only:
   No more late evening watering for me. Damp leaves overnight are a fungal dream. Now, I water the base of the plant in the morning, and that’s it.
3. Trimming and Cleaning:
   Dead leaves? I snip them off. Any leaf that looks funny , discolored, spotty, curling , I remove and toss it far away from the garden. Don’t compost diseased leaves, just to be safe.
4. A Little Neem Oil:
   I spray a very mild neem oil solution around 1 teaspoon per liter of water every couple of weeks when the weather is wet. It’s natural, doesn’t harm the plant, and does the job quietly.

A Neighbor’s Tip That Stuck With Me

One of my neighbors, Shafiq Bhai, has been growing lemongrass behind his kitchen for over a decade. He told me, “If the plant starts looking tired, it’s usually because something’s bothering the roots or the leaves are too wet. Trim it like you would your own hair when it gets scruffy.”

That advice stuck. Keeping it tidy really helps. After pruning, the plant looks fresh, smells stronger, and problems seem to back off.

What Science Says

A 2020 field study from the Bangladesh Agricultural Research Institute showed that lemongrass treated with neem extract had significantly lower fungal infection rates compared to untreated plants, especially during monsoon months. And guess what the key advice was? Good spacing, leaf hygiene, and early intervention , just like what most home gardeners naturally figure out with experience.

Step 9: Harvesting Lemongrass

When your lemongrass stalks are about half an inch thick, they’re ready for the big leagues.

• Using a sharp knife or scissors, cut the stem at ground level.
• Peel away the outer layers to reveal the tender core.

Want to keep the zing going? Dry leftover stalks for tea or freeze them for future soups and curries.

Step 10: Overwintering Lemongrass

If Jack Frost comes knocking, bring your lemongrass indoors. Repot it in a container and place it near a sunny window. No sun? No problem use a grow light. Just don’t forget to water sparingly; lemongrass doesn’t need a tropical vacation in winter.
