Creating the Ideal Growing Conditions

Proper care is essential when growing lemongrass plants, and creating the ideal growing conditions is key to their success. Here are some tips to ensure your plants thrive:


Lemongrass plants need ample sunlight to grow, so choose a location that receives at least six hours of direct sunlight each day. If grown indoors, make sure they’re placed near a sunny window or under grow lights.


Lemongrass plants prefer well-draining soil that is slightly acidic with a pH range between 6.0 and 7.5. You can make your own soil mix by combining equal parts sand, potting soil, and compost.


Lemongrass plants require consistent moisture, but not too much water. Water them deeply once or twice a week, depending on the weather and humidity levels. Allow the soil to dry out slightly between watering, but never let it completely dry out.


Lemongrass plants benefit from regular fertilization during their growing season, which is typically from spring to fall. Use a balanced fertilizer with equal parts nitrogen, phosphorus, and potassium, applying it every two to three weeks.

Following these tips can help ensure your lemongrass plants thrive and produce an abundant harvest.

Planting Lemongrass from Seeds or Transplants

Once you have chosen the right lemongrass plant variety and created the ideal growing conditions, it’s time to plant your lemongrass. There are two methods for planting lemongrass: from seeds or transplants.

Planting Lemongrass from Seeds

If you choose to plant lemongrass from seeds, start by soaking the seeds in water for 24 hours to help soften the outer coating. After soaking, plant the seeds in a seed-starting mix and keep them moist in a warm, sunny area. It may take up to three weeks for the seeds to germinate. Once the plants have grown to a few inches tall, you can transplant them to a larger container or your garden.

Planting Lemongrass from Transplants

If you prefer to plant lemongrass from transplants, purchase healthy plants from a reputable nursery or garden center. Make sure the plants are at least six inches tall and have strong roots. When planting the transplants, dig a hole that is slightly larger than the root ball and fill the hole with soil, pressing down gently to secure the plant in place. Water the plant immediately after planting and keep the soil moist in the following weeks.

Regardless of the planting method you choose, it’s important to space the plants at least 18-24 inches apart to ensure enough room for growth. Also, make sure you plant the lemongrass in well-draining soil so the roots don’t become waterlogged.

It’s best to plant lemongrass in the spring or early summer when temperatures are warmer. This will give the plants enough time to grow and mature before the weather cools down in the fall.

Once your lemongrass is planted, continue to care for it by following the proper maintenance tasks, such as watering, fertilizing, and pest control, which will be covered in the next section.

How to Grow Lemongrass Plants: Proper Lemongrass Plant Maintenance

Caring for your lemongrass plants is essential to maintain their health and productivity. Here are some tips on how to care for your plants:

  • Watering: Lemongrass plants need regular watering, especially during the growing season. Water the plants deeply once or twice a week, making sure the soil is moist but not waterlogged.
  • Fertilizing: Apply a balanced fertilizer every four to six weeks during the growing season to promote healthy growth.
  • Pest control: Check your plants regularly for pests, such as aphids, spider mites, and mealybugs. If you notice any, treat the plants with an insecticidal soap or neem oil solution.
  • Pruning: Prune your lemongrass plants regularly to promote healthy growth and shape. Cut back the leaves to about 6-8 inches from the ground once or twice a year.

Lemongrass Plant Maintenance Tips

Here are some additional tips for maintaining healthy lemongrass plants:

“Mulch your lemongrass plants with a layer of organic material, such as straw or leaves, to help retain moisture and control weeds.”

By following these simple lemongrass plant care suggestions, you can enjoy a bountiful harvest of fresh and flavorful lemongrass for years to come.

Harvesting Lemongrass for Culinary Use

Lemongrass is a popular herb in Asian cuisine, often used to add a refreshing lemony flavor to dishes. Harvesting lemongrass is easy and can be done throughout the growing season. Here’s what you need to know:

When to Harvest:

  • Wait until the plant is at least 12 inches tall before harvesting.
  • Harvest in the morning when the leaves are dry.
  • Harvest before the plant produces flowers or seed heads.

How to Harvest:

  1. Use a sharp knife or scissors to cut the stalks close to the ground.
  2. Remove the tough outer leaves and the upper portion of the stalk, leaving only the tender bottom portion.
  3. Rinse the stalks thoroughly to remove any dirt or debris.

Lemongrass can be used fresh or dried. To dry lemongrass, tie the stalks together and hang them upside down in a dry, well-ventilated area for about a week. Once dry, remove the leaves and store the stalks in an airtight container.

Tip: Lemongrass can also be stored in the freezer for later use. Slice the stalks into small pieces and store in an airtight container or plastic bag.

Lemongrass is a versatile herb that can be used in a variety of dishes, including soups, curries, and marinades. It can also be used to make tea or infused into oils for aromatherapy purposes. So, once you have harvested your lemongrass, start experimenting with different recipes and uses!

Pruning and Trimming Lemongrass Plants

Pruning and trimming lemongrass plants is an essential part of their maintenance and care, promoting healthy growth and shaping.

When pruning, it is crucial to remove any yellow or damaged leaves, stems, and flowers. This step will not only improve the plant’s appearance but also prevent pests and diseases from spreading.

Trimming, on the other hand, involves cutting the leaves and stems to the desired height, depending on the plant’s purpose. If you intend to use lemongrass for cooking, trim the leaves when they are about six inches tall to encourage more growth. If you are using lemongrass for ornamental purposes, you can let it grow as tall as five feet before trimming it.

It is best to trim lemongrass in the spring or early summer, as this gives the plant enough time to grow back before winter.

Common Pests and Diseases of Lemongrass Plants

While lemongrass plants are relatively easy to grow, they can fall victim to pests and diseases if not properly cared for. Understanding the common issues that can affect your lemongrass plants is essential for maintaining their health and productivity.


One of the most common pests that affect lemongrass plants is the red spider mite. These tiny arachnids feed on the sap of the leaves, causing them to turn yellow and eventually die. To prevent red spider mites, ensure that your lemongrass plants are properly watered and the humidity level is not too low. You can also use natural insecticides like neem oil to control their population.

Another pest you may encounter is the lemongrass psyllid. These pests are small, winged insects that feed on the sap of the leaves and cause them to curl and turn yellow. To control their population, prune any affected leaves and apply natural insecticides like insecticidal soap or neem oil.


One of the most common diseases of lemongrass plants is fungal leaf blight. This disease causes yellow spots on the leaves, which eventually turn brown and die. To prevent fungal leaf blight, ensure that your plants are not overcrowded, and there is enough space between them for proper air circulation. You can also apply natural fungicides like copper sulfate or Bordeaux mixture to prevent and treat fungal infections.

Lemongrass rust is another disease that affects lemongrass plants. This fungal infection causes orange-brown pustules to form on the leaves, which eventually turn black and die. To prevent lemongrass rust, make sure that your plants are not overcrowded and are well-spaced. You can also apply natural fungicides like neem oil or garlic oil to control fungal infections.

Propagating Lemongrass through Division

How to Grow Lemongrass Plants

One of the easiest ways to propagate lemongrass plants is through division. This method involves separating mature plants into smaller sections, each with their own roots and shoots, which can be transplanted into new pots or outdoor spaces.

To successfully propagate lemongrass through division, follow these steps:

  1. Water the plant thoroughly a day or two before division to ensure the soil is adequately moist.
  2. Gently remove the lemongrass plant from its pot or outdoor location, being careful not to damage the roots.
  3. Separate the clump of plants into smaller sections using a sharp, clean knife or garden shears. Each section should have at least one root system and several shoots.
  4. Plant each section into a new pot or outdoor location, making sure to bury the roots and base of the shoots in moist soil. Water thoroughly and place in a sunny location.

With proper care and regular watering, newly propagated lemongrass plants should begin to grow within a few weeks.
