Let’s dive into everything you need to know about cultivating this amazing plant!
Understanding the Lemongrass Plant: Varieties and Basics
Two Main Varieties
When you start growing lemongrass plant, you’ll primarily encounter two varieties. West Indian lemongrass (Cymbopogon citratus) is the culinary favorite, widely used in Asian cooking. East Indian lemongogon citratus) is the culinary favorite, widely used in Asian cooking. East Indian lemongrass (Cymbopogon flexuosus) is more commonly grown for oil production. For home gardens, stick with West Indian variety for the best cooking results.
What Makes Lemongrass Special
Lemongrass belongs to the grass family, similar to lawn grass but much more useful! It forms dense clumps with tall, arching stalks that have a distinctive lemony aroma when crushed. The edible portion is the lower stalk, which is pale and slightly bulbous at the base. Unlike many herbs, lemongrass grows quite large, so plan your garden space accordingly. Much like the citronella plant, lemongrass offers both practical and aesthetic benefits to your garden.
How to Start Growing Lemongrass Plant: Three Methods
Method 1: From Grocery Store Stalks (Easiest!)
This is my favorite method because it’s practically free! Next time you’re at the store, pick up a bundle of fresh lemongrass stalks. Look for stalks with intact root bases—those flat bottoms are where new roots will emerge. Trim the tops down to about 4-5 inches, then place the stalks in a jar of water. Set them on a sunny windowsill and change the water every few days. Within 2-3 weeks, you’ll see white roots sprouting from the base. Once roots are about 2 inches long, transplant into soil.
Method 2: From Seeds
If you want to start from scratch, lemongrass seeds work well too. Start seeds indoors 8-10 weeks before the last frost. Sprinkle seeds on top of moist seed-starting mix and press lightly—they need light to germinate. Keep the soil warm (around 70-75°F) and consistently moist. Germination takes 10-14 days. Once seedlings have a few true leaves, transplant them into larger pots or directly outdoors.
Method 3: From Nursery Plants
For the quickest results, buy established lemongrass plants from your local nursery. This method skips the waiting game entirely. Choose plants with healthy green foliage and no signs of pests or disease. Nursery plants are typically ready to harvest within a few weeks of transplanting.
Planting and Care: Creating the Perfect Environment
Sunlight Requirements
Lemongrass is a sun worshipper! It needs a minimum of 6-8 hours of direct sunlight daily. If you’re growing it indoors, place it in your sunniest window—south-facing is ideal. Without enough light, your plant will become leggy and produce less flavorful stalks.
Soil and Container Selection
Use well-draining, nutrient-rich soil with a slightly acidic to neutral pH (6.0-7.0). For container growing, choose pots at least 12 inches deep and wide—lemongrass develops extensive root systems. Make sure containers have drainage holes to prevent root rot. A quality potting mix with added compost works perfectly.
Watering Schedule
Consistency is key when watering lemongrass. Keep the soil evenly moist, especially during hot summer months. Check the top inch of soil—if it feels dry, it’s time to water. Outdoor plants may need daily watering in peak summer, while indoor plants typically need water every 2-3 days. Mulching around the base helps retain moisture.
Fertilizing Tips
Feed your lemongrass plant monthly during the growing season with a balanced liquid fertilizer. Nitrogen-rich fertilizers promote lush, leafy growth. Organic options like fish emulsion or compost tea work wonderfully. Reduce feeding in fall and winter when growth naturally slows.
Harvesting Your Lemongrass Plant
When to Harvest
Your lemongrass plant will be ready for its first harvest about 3-4 months after planting. Look for stalks that are at least half an inch thick at the base. Thinner stalks need more time to develop their full flavor.
How to Harvest Properly
Grab a stalk near the base and twist it firmly, or use a sharp knife to cut at soil level. Always harvest outer stalks first, leaving the inner ones to continue growing. Never harvest more than one-third of the plant at once. The white lower portion is the most flavorful part—use it fresh, dried, or frozen.
Storing Your Harvest
Fresh lemongrass stalks last about 2-3 weeks in the refrigerator wrapped in a damp paper towel. For longer storage, chop stalks and freeze them in airtight bags for up to six months. You can also dry lemongrass by hanging stalks in a warm, dry place for two weeks.
Winter Care and Common Problems
Overwintering Lemongrass
Since lemongrass is tropical, it cannot survive freezing temperatures. If you live in zones 9-11, it may survive winter outdoors with heavy mulching. For everyone else, bring potted plants indoors before the first frost. Place them in a sunny window and reduce watering. The plant may go semi-dormant but will bounce back in spring. Alternatively, dig up a few stalks, trim them, and grow in water on a windowsill for fresh harvest through winter.
Pests and Diseases
Fortunately, lemongrass has few pest problems—its strong scent naturally repels many insects! However, watch for spider mites on indoor plants, especially in dry conditions. Increase humidity by misting leaves regularly. Rust fungus can appear in overly wet conditions; ensure good air circulation and avoid overhead watering.
Conclusion
Growing lemongrass plant at home is a simple, satisfying endeavor that rewards you with fresh flavor and natural beauty.

Frequently Asked Questions
How long does it take to grow a lemongrass plant?
From stalk propagation, lemongrass typically takes 3-4 months to reach harvestable size. Starting from seeds adds about 2-3 weeks for germination, making the total timeline closer to 4-5 months before your first harvest.
Can I grow lemongrass indoors year-round?
Yes, lemongrass grows well indoors as long as it receives 6-8 hours of bright, direct sunlight daily. Place it near a south-facing window and maintain consistent watering. Indoor plants may grow slightly slower but will produce stalks continuously.
Does lemongrass come back every year?
In warm climates (USDA zones 9-11), leongrass acts as a perennial and returns each year. In colder regions, treat it as an annual or bring it indoors for overwintering. With proper care, a single plant can produce for multiple seasons.
How often should I water lemongrass?
Water lemongrass when the top inch of soil feels dry, typically every 1-2 days during hot weather and every 3-4 days for indoor plants. The key is keeping soil consistently moist without becoming waterlogged to prevent root rot.
What can I plant near lemongrass?
Lemongrass grows well alongside tomatoes, peppers, and basil. Its strong scent helps repel certain garden pests, making it an excellent companion plant. Avoid planting it near moisture-sensitive herbs that prefer drier conditions.
Why is my lemongrass turning brown?
Brown leaves usually indicate underwatering, low humidity, or too much direct hot sun without adequate moisture. Check your watering schedule and ensure the plant isn’t sitting in waterlogged soil. Trim brown leaves to encourage fresh growth.
