Why Grow Lemongrass in Pots?
Lemongrass, with its distinctive citrusy aroma and flavor, is a staple in many cuisines, especially in Southeast Asia. But its benefits extend beyond the kitchen. It’s also known for its therapeutic properties, often used in herbal teas and aromatherapy. Growing it yourself offers unparalleled freshness and a continuous supply of this wonderful herb.
For those with limited garden space, container gardening is a fantastic solution. And lemongrass, thanks to its robust nature and preference for well-drained soil and sun, is an excellent candidate for pot cultivation. You can enjoy its culinary uses, its natural insect-repelling qualities, and the sheer joy of nurturing a plant from a simple stalk.
Choosing Your Lemongrass
You have a couple of ways to start your lemongrass growing journey:
- From Store-Bought Stalks: This is the most common and budget-friendly method for beginners. Look for fresh, firm stalks at your local grocery store or farmer’s market. They should have no bruised spots or wilting leaves. The bottom part, where the roots would have been, is key.
- From Seeds: While possible, starting lemongrass from seed can be more challenging and requires a longer growing season. It’s generally recommended for more experienced gardeners.
- From a Nursery Plant: You can also purchase a small lemongrass plant from a garden center. This gives you a head start and is a reliable way to begin.
Getting Started: Essential Supplies
Before you plant, gather these essentials for successful potted lemongrass:
- Lemongrass Stalks: Fresh and healthy from the grocery store, or a nursery plant.
- Pots: Choose pots that are at least 10-12 inches in diameter and depth. Lemongrass grows quite large, so giving it ample space is crucial. Ensure the pots have good drainage holes. Terracotta pots are great as they allow the soil to breathe.
- Potting Mix: A well-draining potting mix is vital. You can use a standard potting mix and amend it with perlite or coarse sand to improve drainage. A good quality organic potting mix is ideal.
- Watering Can: For gentle and consistent watering.
- Sunlight: Lemongrass thrives in full sun.
Starting Your Lemongrass from Store-Bought Stalks: A Step-by-Step Guide
This is where the magic begins! Let’s turn those grocery store stalks into fragrant, thriving plants. It’s a rewarding process that even the most novice gardener can master.
Step 1: Prepare the Stalks
Take your store-bought lemongrass stalks and carefully cut off the top leafy part, about two-thirds of the way up. You want to keep the bulbous bottom section, which is where the roots will emerge.
Discard the leafy tops for now, or save them to add to a stock or potpourri. You can also choose to root the leafy tops separately, but focusing on the bottom is usually more successful for establishing the main plant.
Step 2: Rooting the Stalks
There are two popular methods for rooting your lemongrass stalks:
Method A: Water Propagation
Place the prepared stalk bottoms in a glass or jar filled with water. Ensure the bulbous end is submerged, but the cut leaves are above the water line. Place the jar in a warm spot that receives bright, indirect sunlight. Change the water every few days to keep it fresh and prevent rot. You should start to see tiny white roots emerging from the base within a few weeks.
Method B: Direct Potting
Fill your chosen pot with well-draining potting mix. Make a small hole in the center of the soil and insert the bulbous end of the lemongrass stalk, burying it about an inch deep. Water gently. Keep the soil consistently moist but not waterlogged.
Whichever method you choose, patience is key. It might take a few weeks before you see significant root development or new leaf growth.
Step 3: Planting Your Rooted Lemongrass
Once your stalks have developed a good root system (about 1-2 inches long in water propagation) or have shown signs of new growth from direct potting, it’s time to plant them in their permanent pot. If you started in water, carefully transfer the rooted stalks into a pot filled with your well-draining potting mix.
Gently place the stalk, ensuring the roots are spread out, and cover with soil. Water thoroughly. If you’re planting multiple stalks in the same pot, space them about 6-8 inches apart, as they will grow to be bushy.
Essential Care for Your Potted Lemongrass
Now that your lemongrass is planted, providing the right care will ensure it thrives.
1. Sunlight Requirements
Lemongrass is a sun-worshipper! It needs at least 6-8 hours of direct sunlight per day. If you’re growing it indoors, a south-facing window is ideal. If you have a patio or balcony, choose the sunniest spot you have. Insufficient sunlight can lead to leggy growth and a less potent aroma.
2. Watering Needs
Consistent moisture is important, especially when your plant is young and establishing itself. Water your lemongrass thoroughly whenever the top inch of soil feels dry to the touch. Overwatering can lead to root rot, so ensure your pot has excellent drainage. In hot, dry weather, you might need to water more frequently. Tropical plants like lemongrass enjoy humidity, so misting occasionally can be beneficial, especially if you live in an arid climate.
3. Soil and Potting Mix
As mentioned, well-draining soil is non-negotiable. A good quality potting mix amended with perlite or coarse sand works wonders. You can also incorporate a bit of compost for added nutrients. Ensure the pot has drainage holes to prevent waterlogging. For a more sustainable approach, consider researching homemade compost recipes.
4. Temperature and Climate
Lemongrass is a tropical plant and thrives in warm temperatures, ideally between 65°F and 85°F (18°C – 29°C). It generally doesn’t tolerate frost well. If you live in a region with cold winters, you’ll need to bring your potted lemongrass indoors when temperatures start to drop.
5. Fertilizing
Lemongrass is a relatively heavy feeder. During its active growing season (spring and summer), feed it with a balanced, water-soluble fertilizer every 4-6 weeks. Alternatively, you can incorporate some slow-release organic fertilizer into the soil at the beginning of the growing season. Avoid over-fertilizing, which can harm the plant.
When and How to Harvest Your Lemongrass
The best part – harvesting your homegrown bounty! You can begin harvesting once the stalks are about ½ to ¾ inch in diameter at the base. This usually takes about 6-8 months after planting, but can vary.
- Harvesting Technique: To harvest, simply cut the stalks at the base, about 1-2 inches above the soil line. This encourages the plant to regrow. Alternatively, you can pull out an entire stalk by the roots if you need a larger amount.
- What to Use: The lower, bulbous part of the stalk is the most tender and flavorful. The outer layers can be tough and fibrous, so peel these away to reveal the tender inner core. The leaves can also be used for flavoring stock or for making tea, adding a lighter, more subtle aroma.
- Frequency: You can harvest individual stalks as needed to maintain a steady supply without depleting the plant. With proper care, your potted lemongrass can be harvested multiple times a year.
Common Pests and Problems (and How to Solve Them)
While generally resilient, potted lemongrass can sometimes encounter issues. Here are a few common ones:
- Root Rot: Caused by overwatering and poor drainage. Ensure your pot has drainage holes and let the soil dry out slightly between waterings.
- Yellowing Leaves: This can be a sign of insufficient sunlight, overwatering, or nutrient deficiency. Assess your watering schedule and light exposure. If those are adequate, consider fertilizing.
- Aphids and Spider Mites: These tiny pests can sometimes infest lemongrass. A strong blast of water from your hose can often dislodge them. For more persistent infestations, use insecticidal soap or neem oil, following product instructions carefully. For more natural pest control options, explore resources from organizations like the University of California Master Gardener Program.
Overwintering Potted Lemongrass
If you live in a climate that experiences frost or freezing temperatures, you’ll need to protect your lemongrass during the winter months.
Option 1: Bring Indoors
As soon as temperatures consistently drop below 50°F (10°C), bring your potted lemongrass inside. Place it in your sunniest window and continue to care for it, though watering needs will decrease significantly in lower light and cooler indoor conditions.
Option 2: Prune and Protect Outdoors (for milder climates)
In climates that rarely freeze but get cooler, you can significantly prune back the plant (leaving about 6-8 inches of growth) and cover the pot with mulch or burlap to insulate the roots. This is less reliable than bringing it indoors and might not be suitable for areas with hard freezes.
Lemongrass Varieties for Pots
While the common lemongrass (Cymbopogon citratus) is widely available and suitable for pots, there are variations. However, for beginner container gardeners, sticking to the readily available Cymbopogon citratus is your best bet. It’s hardy, forgiving, and widely recognized for its culinary uses. Other varieties might exist but are less common in typical grocery stores.
