Lemongrass. Sounds like a fancy spa treatment, but it’s actually a seriously versatile plant. If you’ve never tasted it, lemongrass is like a citrusy breeze with a little zing, a perfect balance of fresh, bright flavor without being too sharp. It’s one of those plants that makes you feel like you’ve got your life together—herby, aromatic, and great for everything from teas to soups to stir-fries.
It thrives in warm climates (like most things that love the sun), and, here’s the kicker—it’s practically impossible to kill. I mean, you might forget to water it for a week and it’ll still come back like nothing happened. It grows best in full sun, but don’t expect it to do well in pots unless you’re super dedicated to giving it the space it craves. Lemongrass loves to spread out, so plant it in the ground, and you’ll be rewarded with a lovely, fragrant grass that can grow over 3 feet tall.
If you’re new to growing it, give it a little love in the early stages—regular watering, and a little mulch to keep the roots cool. Once it’s established, it’s low maintenance. Plus, you can snip off stalks as needed and use them in cooking or even make a soothing lemongrass tea that’ll make you feel like you’re on vacation.
And the best part? It’s practically a miracle worker when it comes to warding off pests. Talk about earning your keep!
How to Grow Lemongrass
Growing lemongrass is a rewarding process, especially for those who enjoy its fresh, citrusy flavor in cooking. Below is a comprehensive guide.
Planting Lemongrass
- Choose the Right Location: Lemongrass thrives in warm, sunny locations with well-draining soil. It prefers a spot that gets at least 6-8 hours of sunlight per day.
- Prepare the Soil: Lemongrass prefers rich, loamy soil. If your soil is heavy or clay-like, amend it with compost or organic matter to improve drainage.
- Planting:
- From Stalks: If you’re planting from store-bought stalks, choose healthy ones with a firm base. Place the stalks in water until roots begin to form, usually within a few weeks. Then, transplant them into the soil.
- From Seeds: If planting from seeds, sow them directly into the soil after the last frost or start them indoors 6-8 weeks before the last frost. Plant seeds about 1/4 inch deep in the soil.
- Spacing: Plant lemongrass stalks or seedlings 24 inches apart to allow enough space for the plant to grow and spread.
Growing Lemongrass
- Watering: Lemongrass likes moist soil, so water it regularly, especially during dry spells. However, avoid waterlogging the soil.
- Fertilizing: Feed lemongrass with a balanced organic fertilizer every 4-6 weeks during the growing season to encourage healthy growth.
- Mulching: Apply a layer of mulch around the base of the plants to help retain moisture and suppress weeds.
- Pruning: Trim the tops of the plant regularly to encourage bushier growth. Removing old or dead stalks also helps the plant stay healthy.
Harvesting Lemongrass
- When to Harvest: You can start harvesting lemongrass once the stalks are at least 12 inches tall and about 1/2 inch thick. The best time to harvest is when the plant is fully mature, usually in late summer or early fall.
- How to Harvest:
- Cut the stalks close to the ground using a sharp knife or garden shears.
- For a continuous harvest, only remove a few stalks at a time, allowing the rest to continue growing.
- Use the lower, white part of the stalks for cooking, and save the leaves for teas or infusions.
- Storage: Fresh lemongrass stalks can be stored in the refrigerator for up to two weeks. You can also freeze them for longer storage by chopping the stalks into pieces and placing them in an airtight container.
Lemongrass Growing Zone
Lemongrass (Cymbopogon citratus) thrives in warm, tropical climates and is best suited for USDA hardiness zones 9 through 11.
In these zones, it can be grown outdoors year-round as it is a tender perennial in warmer climates.
- Zone 9: Lemongrass may need some protection during cold snaps, as it can be damaged by frost.
- Zones 10-11: Ideal for lemongrass, where it can grow vigorously without the risk of frost damage.
In cooler climates outside of these zones, lemongrass can be grown as an annual, or it can be brought indoors during the winter to protect it from freezing temperatures.
Growing Lemongrass FAQ
Yes, lemongrass grows well in containers. Choose a large pot with good drainage, and ensure the plant gets plenty of sunlight. Container-grown lemongrass can be moved indoors during colder months.
Plant lemongrass in the spring, after the last frost. If planting from stalks, choose fresh, firm ones with a bit of the base intact. Plant the stalks about 1 inch deep in moist soil and space them about 24 inches apart.
Yes, lemongrass can be grown indoors if it gets plenty of sunlight. Place the plant near a sunny window, and consider using grow lights if natural light is insufficient.
You can start harvesting lemongrass when the stalks are about 12 inches tall and at least 1/2 inch thick. Cut the stalks at ground level, or harvest the outer stalks first and leave the inner ones to continue growing.
Lemongrass can be propagated by division or by rooting stalks. To divide, dig up the clump and separate the individual stalks with roots attached. Replant immediately. For rooting, place stalks in water until roots form, then plant in soil.
Lemongrass typically takes about 4-8 months to reach full maturity, depending on the growing conditions. However, you can start harvesting earlier if the stalks are large enough.
While lemongrass can tolerate short periods of drought, it grows best with consistent moisture. During dry spells, make sure to water it regularly to keep the soil evenly moist.
