- Sustainable Living: Growing your own herbs reduces your carbon footprint by cutting down on transportation and packaging. It’s a wonderful step towards an eco-friendlier lifestyle.
- Aromatic Delight: Even if you primarily grow it for tea, the plant itself is beautiful and smells amazing, adding a lovely scent to your garden or home.
- Versatile Ingredient: Beyond tea, fresh lemongrass is a fantastic addition to marinades, soups, curries, and even homemade cleaning solutions.
Getting Started: What You Need to Grow Lemongrass
Fear not, budding gardeners! You don’t need a complex setup to start growing lemongrass. Here’s a simple checklist to get you rolling:
Outdoor Gardening Essentials:
- Sunlight: Lemongrass absolutely craves sun. Aim for a spot that gets at least 6-8 hours of direct sunlight daily.
- Soil: It prefers well-draining soil. If your soil is heavy or clay-like, consider amending it with compost or sand to improve drainage. Raised beds or containers are also excellent options for ensuring good drainage.
- Space: Lemongrass can grow into a substantial clump, so give it a bit of room to spread. A spacing of about 2-3 feet between plants is ideal for outdoor beds.
- Water: While established plants are somewhat drought-tolerant, they grow best with consistent moisture. Water deeply when the top inch of soil feels dry.
Indoor Gardening Essentials:
- A Sunny Window: Just like outdoors, indoor lemongrass needs plenty of light. A south-facing window is usually best. If you don’t have one, consider using a grow light.
- Pot: Choose a pot that is at least 8-10 inches in diameter and has good drainage holes. Lemongrass has extensive roots, so a larger pot is better for long-term growth.
- Potting Mix: Use a good quality, well-draining potting mix. You can enhance drainage further by adding perlite or coarse sand.
- Watering Can: For regular watering.
How to Plant Lemongrass: From Store-Bought Stalks to Garden Gold
Did you know you can often start lemongrass directly from the stalks you buy at the grocery store? It’s a fantastic and economical way to begin your lemongrass-growing adventure!
Method 1: Starting from Grocery Store Stalks (The Easiest Way!)
This is a crowd-pleaser for a reason – it’s incredibly simple and budget-friendly!
- Select Your Stalks: Head to the produce aisle and pick out a few fresh-looking stalks of lemongrass. Look for ones that are firm and have a light, creamy base. Avoid any that are wilted or have brown spots. Ideally, find stalks that still have some root fibrousness at the base.
- Prepare the Stalks: Trim off the top leafy green parts by about an inch. You can also trim off the very bottom tough end, but be careful not to cut into the root area.
- Root in Water: Place the prepared stalks in a glass or jar filled with a few inches of water. Make sure the root end is submerged, but the cut top is not.
- Find a Sunny Spot: Place the jar in a warm, bright location, like a sunny windowsill.
- Change the Water: Change the water every few days to keep it fresh and prevent bacteria from growing.
- Watch for Roots: Within a week or two, you should start to see small white roots emerging from the base of the stalks. The leafy tops might also start to sprout new green growth.
- Planting Time: Once the roots are about an inch long and you see new growth, your lemongrass is ready to be planted!
Method 2: Planting from Seedlings or Divisions
If you’ve purchased lemongrass seedlings from a nursery or have a mature plant you want to divide, the process is straightforward:
- Choose Your Location: Select a sunny spot outdoors, or a large pot indoors with good drainage.
- Prepare the Soil: Amend your garden soil with compost for nutrients and ensure it drains well. For pots, use a quality potting mix.
- Dig a Hole: Dig a hole large enough to comfortably accommodate the root ball of your seedling or division.
- Plant: Gently place the lemongrass plant in the hole, ensuring the top of the root ball is level with the soil surface. If planting multiple, space them about 2-3 feet apart for outdoor growth.
- Backfill and Water: Fill the hole with soil, pat down gently, and water thoroughly.
Essential Lemongrass Care: Sunshine, Water, and a Little Love
Once your lemongrass is planted, it’s time to give it the TLC it needs to thrive. Luckily, it’s a pretty forgiving plant!
Sunlight: The More, The Merrier!
Lemongrass is a sun-worshipper. For the best growth and flavour development, ensure your plant receives at least 6 to 8 hours of direct sunlight daily. In cooler climates, south-facing locations are ideal. If growing indoors, a very bright window is crucial. Insufficient light can lead to leggy, weak growth and reduced flavour. If you’re struggling to get enough natural light, consider supplementing with a grow light, especially during winter months. The reputable Oregon State University Extension Service offers excellent advice on optimizing plant light exposure: Understanding Grow Lights for Indoor Plants.
Watering Wisely: Keep it Consistently Moist
Lemongrass loves consistent moisture, especially during its active growing season (spring and summer). Aim to water when the top inch of soil feels dry to the touch. Avoid letting the soil dry out completely, as this can stress the plant. Water deeply until you see it draining from the pot’s holes. In very hot weather, you might need to water more frequently. Reduce watering in cooler months or if growing indoors during winter, but don’t let it become bone dry.
Feeding Your Lemongrass: A Gentle Boost
Lemongrass isn’t a heavy feeder, but it does appreciate a little nourishment, particularly when grown in pots, where nutrients can leach out quicker.
- Outdoor Plants: In spring, you can amend the soil with a layer of compost. A light feeding with a balanced, slow-release organic fertilizer once in spring and again in mid-summer is usually sufficient.
- Indoor Plants: Feed your potted lemongrass with a balanced liquid fertilizer diluted to half strength every 4-6 weeks during the growing season (spring and summer).
Avoid over-fertilizing, as this can lead to excessive leafy growth at the expense of stalk development and flavour.
Temperature and Humidity: Tropical Preferences
Lemongrass is a tropical grass, so it thrives in warmth. It performs best in temperatures between 65°F and 85°F (18°C to 30°C). It can tolerate short periods of cooler weather, but prolonged exposure to temperatures below 50°F (10°C) can cause damage. If you live in a region with cold winters, you’ll need to bring your lemongrass indoors or treat it as an annual.
In terms of humidity, lemongrass appreciates higher levels. If your indoor environment is particularly dry, especially during winter when heating systems are running, you can increase humidity by placing the pot on a pebble tray filled with water (make sure the pot isn’t sitting directly in the water) or by misting the leaves occasionally.
Pruning and Maintenance: Keeping it Tidy
Lemongrass can grow into a dense clump. You can prune it back to maintain its shape and encourage new growth. In late winter or early spring, before new growth really kicks in, you can trim back the old, dried-out leaves. This also makes it easier to harvest. If the clump becomes too large or overcrowded, you can divide it. This is also a good time to check for any signs of pests or diseases.
Harvesting Your Bountiful Lemongrass
The most exciting part! Harvesting your homegrown lemongrass is incredibly satisfying. You can start harvesting once the plant is well-established and has developed thick stalks, typically a few months after planting.
When to Harvest:
- Look for thick, firm stalks that are at least ½ inch in diameter.
- The base of the stalks should be a pale yellow or creamy white.
- Harvesting is best done in the morning after the dew has dried.
How to harvest:
- For Individual Stalks: Use a sharp knife or gardening shears to cut a stalk at its base, as close to the ground as possible. Twist and pull gently if you can’t get a clean cut. Be careful not to damage the main plant.
- For Divisions/Rejuvenation: You can cut back the entire plant by about a third, which will encourage new growth and make it easier to harvest individual stalks.
What to Harvest: You’re primarily interested in the lower, thicker portion of the stalk, from where it emerges from the soil up to where the leaves start to divide. The tender, bulbous base is where most of the flavour resides.
Storing Your Harvest
Freshly harvested lemongrass is best used immediately, but you can store it for later use:
- Refrigeration: Wrap the harvested stalks tightly in plastic wrap or place them in an airtight bag. They can last in the refrigerator for 1-2 weeks.
- Freezing: Cut the stalks into smaller pieces (about 2-3 inches long) and freeze them in an airtight container or freezer bag. Frozen lemongrass is excellent for teas and slow-cooked dishes.
-
Drying: While not as potent as fresh or frozen, you can dry chopped lemongrass. Spread the chopped pieces on a screen or baking sheet in a warm, dry place, or use a dehydrator on a low setting until completely dry. Store in an airtight container.

Troubleshooting Common Lemongrass Puzzles
Even experienced gardeners encounter a hiccup now and then. Here are some common lemongrass issues and how to solve them:
Problem: Yellowing Leaves
Cause: This can be due to several factors:
- Underwatering: Soil is too dry.
- Overwatering: Soil is waterlogged, leading to root rot.
- Nutrient Deficiency: Lack of nitrogen or other essential nutrients.
- Cold Temperatures: Exposure to chill can cause yellowing.
Solution: Check your watering habits, ensure good drainage, feed with a balanced fertilizer if needed, and protect from cold. For indoor plants, ensure they are not sitting in a draft.
Problem: Leggy Growth (Tall and Sparse)
Cause: Insufficient sunlight. Lemongrass needs at least 6-8 hours of direct sun per day.
Solution: Move the plant to a sunnier location. If growing indoors, consider using a grow light. Prune back leggy stems to encourage bushier growth.
Problem: No Aroma or Flavour
Cause: The plant may be too young, not receiving enough sun, or harvested too early. Older, tougher stalks can also have diminished flavour if not harvested correctly.
Solution: Ensure adequate sunlight and warmth. Harvest stalks when they are thick and fragrant. For optimum flavour, harvest from established plants, focusing on the lower, tender portions of the stalk.
Problem: Pests (Spittlebugs, Aphids, Spider Mites)
Cause: Common garden and houseplant pests can sometimes find lemongrass.
Solution: Often, a strong spray of water can dislodge many common pests like aphids and spittlebugs. For more persistent infestations, use organic insecticidal soap or neem oil, following product instructions carefully. Healthy plants are less susceptible, so good care is your best defense.
Companion Planting: A Garden’s Best Friends
Lemongrass can be a fantastic neighbour in your garden! Its strong scent can help deter certain pests, making it a useful companion for many vegetables and herbs.
Ideal Companions:
- Tomatoes: Lemongrass can help deter tomato hornworms and whiteflies.
- Peppers: Similar pest deterrence benefits.
- Beans and Peas: Can help ward off bean beetles.
- Roses: Its citrusy aroma can deter aphids.
- Herbs like Basil and Mint: They generally coexist well and can benefit from shared pest resistance.
Plants to Keep Apart (Generally):
- Some gardeners find that lemongrass doesn’t perform as well near larger, more aggressive plants that might shade it out or compete heavily for resources.
Lemongrass Varieties and Their Uses
While Cymbopogon citratus is the most common for culinary and tea purposes, there are other related species and cultivars you might encounter:
Common Lemongrass (Cymbopogon citratus)
- Characteristics: This is the workhorse for most home growers. It has sturdy stalks and a strong, refreshing citrus aroma.
- Uses: Excellent for teas, marinades, stir-fries, soups (like Tom Yum), and infused oils. It’s the go-to for its classic lemony flavour.
East Indian Lemongrass (Cymbopogon flexuosus)
- Characteristics: Often has a more delicate, rosier scent and a slightly sharper flavour profile. The stalks might be thinner.
- Uses: Popular in traditional Ayurvedic medicine and in certain Asian cuisines. It’s also used in perfumery and aromatherapy.
Java Lemongrass (Cymbopogon nardus)
- Characteristics: Known more commonly as Citronella. It has a very strong, distinct aroma.
- Uses: Primarily used for its insect-repelling properties (hence the name Citronella). Its flavour is generally too strong and less pleasant for direct culinary use or regular tea compared to C. citratus.
When growing for tea, Cymbopogon citratus is your best bet for that familiar, soothing citrus flavour.
