Choosing the Right Container and Soil
When growing lemongrass in containers, selecting the right container and soil is crucial to ensure healthy growth and prevent root bound issues. Choose wisely for optimal results!
Understanding Lemongrass Needs
When it comes to growing lemongrass in containers, one of the most critical factors is ensuring proper drainage. Lemongrass prefers well-draining soil that won’t retain too much moisture, which can lead to root rot and other problems.
Proper drainage is essential because it prevents waterlogged soil, a common issue with containers. Water can easily collect at the bottom of the pot, causing roots to sit in standing water. This can be detrimental to lemongrass growth, as its roots are sensitive to excessive moisture.
To avoid this problem, choose a container with good air circulation and a drainage hole or two. Make sure the soil has some organic matter added, such as compost or perlite, which will help it drain excess water. Also, consider repotting your lemongrass every 6-12 months to refresh the soil and ensure good drainage.
A well-draining potting mix can also make a big difference in your lemongrass’s health. Look for mixes specifically designed for tropical plants like lemongrass, which will have ingredients that help with moisture retention while still allowing excess water to drain away. By paying attention to these details, you’ll be able to create an ideal environment for your lemongrass to thrive in its container.
Selecting the Perfect Pot Size
When selecting a pot size for your lemongrass plant, it’s essential to consider its mature height and root depth. Lemongrass can grow quite tall, up to 3-4 feet (90-120 cm), so you’ll want a pot that’s deep enough to accommodate its long roots.
As a general rule of thumb, choose a container that is at least 6-8 inches (15-20 cm) deeper than the plant’s mature height. This will give your lemongrass room to grow without becoming waterlogged or developing root bound conditions.
For example, if you’re growing a compact variety like ‘Moor Park’, which typically reaches around 2 feet (60 cm) in height, a pot with a depth of around 6-8 inches would be suitable. However, if you’re growing the more vigorous ‘Silver Shadow’ variety, which can reach heights of up to 4 feet, you’ll need a deeper container – at least 10-12 inches deep.
Make sure your pot also has good drainage holes in the bottom to prevent waterlogged soil and root rot.
Soil Preparation: pH Levels and Mixtures
When it comes to growing lemongrass in containers, choosing the right soil mix is crucial for the plant’s health and productivity. Lemongrass prefers a slightly acidic to neutral soil pH, ranging from 6.0 to 7.0. This pH range allows for optimal nutrient uptake and water retention, which are essential for lemongrass growth.
To create an ideal soil mix for your container-grown lemongrass, start by combining a good quality potting mix with organic matter such as compost or well-rotted manure. A 1:1 ratio of potting mix to organic matter is a good starting point. Add in some perlite or vermiculite to improve drainage and prevent waterlogged soil.
When selecting an organic matter, look for products that are high in nitrogen, phosphorus, and potassium (NPK). These nutrients will promote healthy growth, root development, and fruiting. A 10-10-10 NPK ratio is a good starting point. Remember to mix the ingredients well to create a uniform blend.

When planting lemongrass in containers, it’s essential to choose a pot that is at least 6-8 inches deep and has good drainage holes to prevent waterlogged soil. Let’s dive into the specifics of container growing for this tropical beauty!
Propagation Methods: Stolons vs. Seeds
When it comes to propagating lemongrass in containers, you have two primary options: using stolons or sowing seeds. Both methods have their advantages and disadvantages, which we’ll explore below.
Propagating through stolons is a popular method for growing lemongrass, as it allows you to harvest multiple stems from the mother plant. To do this, simply cut off the stolon tips (the long, thin stems that grow horizontally) from your mature lemongrass plant and plant them in well-draining soil. Keep the soil consistently moist but not waterlogged, and within a few weeks, new shoots will emerge. This method has a relatively high success rate, with some growers reporting germination rates of up to 80%.
On the other hand, sowing seeds can be a more challenging process. Lemongrass seeds have a notoriously low germination rate (typically around 20-30%), and it may take several months for seedlings to mature. However, this method is beneficial if you’re looking to introduce new varieties or propagate lemongrass in areas where the plant hasn’t been grown before.
To achieve success with either method, make sure to choose high-quality planting material (either stolon tips or seeds) and provide your plants with optimal growing conditions. This includes plenty of sunlight, well-draining soil, and regular watering.
Preparing the Container for Planting
When it comes to growing lemongrass in containers, proper container preparation is crucial for the plant’s success. Before planting your lemongrass, make sure the container is ready with a fresh potting mix and adequate drainage.
Start by selecting a well-draining potting mix specifically designed for tropical plants like lemongrass. Avoid using regular garden soil, as it can compact and prevent proper water absorption. You can also repurpose an old pot or create your own mix using perlite, vermiculite, and compost.
Ensure the container has enough drainage holes to prevent waterlogged roots. If you’re reusing a container, check if it already has holes; if not, drill some 1-2 inches from the bottom for optimal drainage. You can also use a pot with built-in drainage channels or add a layer of small rocks at the bottom to further improve drainage.
Fill the container about 1/3 to 1/2 with fresh potting mix, leaving enough space for your lemongrass plant and any additional soil that may be needed during watering. This will provide a solid foundation for your lemongrass to grow strong and healthy roots.
Planting Lemongrass Stolons or Seeds
When planting lemongrass in containers, you have two options: using stolons or seeds. Both methods have their own advantages and disadvantages, but with the right guidance, you can successfully grow lemongrass in a container.
To plant lemongrass stolons, start by trimming the stolon into sections of about 6-8 inches long. This will help encourage new roots to form and make it easier for your lemongrass plant to establish itself in its pot. Next, prepare a well-draining container with a mix of potting soil and perlite or vermiculite. Plant the stolon section about 1 inch deep, making sure the base of the leaves is above the soil level.
When using seeds, sow them directly into the prepared container about ¼ inch deep. Keep the soil consistently moist during the first few weeks after planting. Regardless of whether you’re starting with stolons or seeds, make sure to water your lemongrass plant thoroughly and keep the potting mix moist but not waterlogged. This will give your lemongrass a strong start in its container home.
Remember, it’s essential to choose healthy lemongrass plants or seeds for optimal growth. Check for any signs of pests or diseases before planting, and disinfect your tools regularly to prevent cross-contamination. By following these simple steps, you’ll be on your way to successfully growing lemongrass in a container.
Care and Maintenance Tips
To keep your lemongrass container garden thriving, be sure to water regularly, fertilize occasionally, and prune back overgrown stalks as needed. With proper care, you’ll enjoy a lush and fragrant harvest all season long.
Watering Habits: Frequency and Moisture Levels
When it comes to growing lemongrass in containers, watering habits play a crucial role in determining its success. Lemongrass prefers well-draining soil and adequate moisture, but overwatering can be detrimental to its health.
Water your lemongrass plant when the top 1-2 inches of soil feel dry to the touch, which is usually every 2-3 days during the spring and summer months. However, during the fall and winter, reduce watering frequency to once a week as the plant requires less moisture in cooler temperatures.
To check the moisture level, stick your finger into the soil up to the knuckle, and if it feels dry, it’s time to water. Water thoroughly until you see water coming out of the drainage holes, making sure not to let the pot sit in water.
Aim for a slightly moist but not soggy consistency, as lemongrass is susceptible to root rot when the soil is consistently waterlogged. By following this watering schedule and monitoring moisture levels, your container-grown lemongrass will thrive, producing fragrant stalks and leaves year-round.
Fertilization Schedule: Organic vs. Synthetic Options
When it comes to fertilizing your container-grown lemongrass, you have two main options: organic and synthetic fertilizers. Understanding the difference between these two types is crucial to providing your plant with the necessary nutrients for healthy growth.
Organic fertilizers are made from natural ingredients such as fish bone meal, alfalfa meal, or compost. These fertilizers release their nutrients slowly over time, promoting a steady supply of nutrients for your lemongrass. For example, you can use compost tea by steeping 1 cup of compost in 5 gallons of water for 24 hours, then watering your plant with the liquid. This method is easy to implement and promotes beneficial microbial growth.
Synthetic fertilizers, on the other hand, are made from chemical compounds that release their nutrients quickly. These fertilizers can be more convenient but may require frequent applications to prevent over-fertilization. A general rule of thumb for container-grown lemongrass is to apply synthetic fertilizers once a month during the growing season (spring and summer), following the recommended dosage on the package label.
Some examples of organic fertilizer schedules for lemongrass include:
* Fish bone meal: Apply 1-2 tablespoons per gallon of water every 4-6 weeks
* Alfalfa meal: Mix 1 tablespoon with 10 gallons of water and apply every 2-3 weeks
Remember to always follow the recommended application rates for synthetic fertilizers, as over-fertilization can harm your plant. It’s also essential to balance these applications with regular watering and pruning practices.
Pruning Techniques: Encouraging New Growth
Pruning lemongrass plants is an essential part of their care and maintenance. Not only does it encourage healthy growth, but it also helps control the plant’s size and promotes new stems to grow. To prune your lemongrass effectively, start by identifying the oldest leaves at the base of the plant. These are usually thicker and more woody than the newer leaves.
Remove these older leaves as close to the soil line as possible, using a sharp pair of scissors or pruning shears. This will help direct the plant’s energy towards producing new growth rather than supporting weak and dying foliage. Next, use your fingers or a blunt instrument to gently pinch off any tips that are flowering or becoming too leggy.
By regularly pinching and trimming lemongrass plants, you’ll encourage bushy growth and prevent them from becoming too tall and difficult to manage in containers. Remember to prune your lemongrass during the growing season when it’s actively producing new leaves. This will help keep the plant healthy, vigorous, and producing plenty of fresh leaves for cooking.

Harvesting Lemongrass in Containers
Now that you’ve successfully grown your lemongrass in a container, it’s time to harvest it – and we’ll walk you through how to do so without damaging the plant. We’ll cover the ideal timing and techniques for harvesting.
Timing and Frequency of Harvests
When it comes to harvesting lemongrass grown in containers, timing and frequency are crucial to encourage continued growth and prevent the plant from flowering. Generally, you should start harvesting when your lemongrass plants have reached a height of about 12-18 inches (30-45 cm). This is usually around 3-4 months after planting, depending on factors like soil quality, temperature, and humidity.
Harvesting too early can stress the plant and lead to reduced growth. Conversely, waiting too long may cause the plant to flower, which reduces its potency and flavor. To avoid this, harvest individual stalks when they reach a suitable size, typically 6-8 inches (15-20 cm) above the node from where new growth begins.
Harvesting frequency also plays a significant role. For optimal results, consider harvesting every 2-3 weeks, leaving about one-third of the plant intact to allow for continued growth. This way, you can enjoy fresh lemongrass throughout the growing season while still allowing your plants to recover and thrive. By striking this balance, you’ll be able to reap the benefits of your container-grown lemongrass while promoting a healthy, sustainable harvest cycle.
Proper Cutting Techniques: Stems and Leaves
When harvesting lemongrass from containers, it’s essential to use proper cutting techniques to promote healthy growth and prevent damage to the plant. Start by identifying the mature stalks, which are typically thicker than the younger ones. Cut these stems at a 45-degree angle using clean, sharp scissors or pruning shears. Make the cut just above a node – the joint where a leaf meets the stem.
This technique encourages new growth and helps prevent the plant from becoming leggy. When cutting lemongrass leaves, use the same clean and sharp tools to avoid spreading any potential diseases. Cut off any dead or damaged leaves, as these can weaken the plant over time. To prevent the cut ends from drying out, you can apply a thin layer of water or a gentle fertilizer. Be cautious not to damage the rhizome – the underground stem that produces new growth – when cutting lemongrass in containers. This will help ensure your lemongrass plant continues to thrive and produce plenty of stalks for future harvests.
