It is important to understand how to grow, harvest, divide, and use lemongrass to get the most out of this versatile plant. Let’s take a look at the best practices for caring for it so that you can make the most of this herb.

Watering and irrigation needs

Watering Frequency: It requires adequate watering, but avoid overwatering. In general, watering 2-3 times a week will ensure healthy growth.

Irrigation: Drip Irrigation or soaker hoses are the most effective irrigation methods for lemongrass. They provide consistent moisture to the roots without causing excess moisture on the foliage.

Soil Drainage: It grows best in well-draining soil. Poor drainage can lead to root rot and stunted growth. Consider amending the soil with compost to improve drainage.

Mulching: Mulching around the lemongrass plant can help retain moisture in the soil and reduce watering needs.

Fertilization requirements

  • Nitrogen: Lemongrass thrives in soil that is rich in nitrogen, a mineral that promotes the growth of leaves, stems, and roots. Adding nitrogen-rich fertilizers like blood meal, fish emulsion, or alfalfa meal to the soil can help boost its growth.
  • Phosphorus and Potassium: Along with nitrogen, it requires a steady supply of phosphorus and potassium to grow healthy and produce maximum yield. Phosphorus promotes the growth of roots and flowers, while potassium helps build plant resistance against pests and diseases. Adding bone meal or rock phosphate for phosphorus and potash for potassium to the soil can be beneficial for the plant.
  • Organic fertilizers: Organic fertilizers like compost or worm castings can also be used to provide the necessary nutrients to it. These fertilizers are rich in essential minerals and create a healthy soil environment for the plant to grow.

Here are some tips for caring for your lemongrass and keeping pests and diseases at bay:

  • Preventing Diseases: It is susceptible to fungal and bacterial infections, especially when grown in damp conditions. To prevent diseases, make sure you plant your lemongrass in well-drained soil, avoid overwatering, and provide good air circulation around the plants.
  • Controlling Pests: Common pests that can attack lemongrass include aphids, spider mites, and mealybugs. These can be controlled by regularly spraying the plants with a neem oil solution or insecticidal soap.
  • Harvesting Practices: Always harvest it with clean and sanitized tools, as a plant can become infected through open wounds. Following these simple tips can keep your lemongrass plants healthy and productive for years.

  • Look for clumps that are too large for their pot or planting area or if the center of the clump looks dead, dry, or unhealthy.
  • Use a sharp, clean pair of shears to clip off any dead, damaged, or dried-up leaves from the bottom of the clump.
  • Gently remove the entire clump from its pot or planting spot and divide it into two to four smaller clumps using a clean, sharp knife or pruning shears.
  • Replant the smaller clumps in a new pot or planting area and keep them well-watered and in a partially shaded area for the first week after transplant.

Pro tip – You can use a rooting hormone powder on the cut parts to help the new plants establish more quickly.

How to divide and transplant lemongrass

Dividing and transplanting lemongrass is a straightforward process that can help control the plant’s size and increase your yield. Here are the steps to follow:

  • Start by digging up the clump, being careful not to damage the roots. Use a sharp knife or garden shears to cut the clump into smaller sections, each with at least one healthy root system and a few stalks of leaves.
  • Fill a container with well-draining soil mixed with compost and water until the soil is moist but not waterlogged.
  • Plant each lemongrass section in the container, ensuring that the plant’s base is at the same level as the soil surface.
  • Water the plants thoroughly, and place them in a sunny area with partial shade. Water regularly and fertilize every few weeks for the best results.

Pro tip: Harvest it by cutting the outer stalks close to the base, leaving the inner stalks to continue growing.

Caring for newly transplanted lemongrass

This is crucial to ensure its successful growth and development. Here are some tips to follow:

  • Watering: Water newly transplanted lemongrass immediately after planting to help settle the soil. Then, water every few days to keep the soil consistently moist, but not waterlogged.
  • Sunlight: It requires full sunlight to grow, so plant it in a spot where it will receive at least 6 hours of direct sunlight daily.
  • Fertilization: Use nitrogen-rich fertilizer to help your lemongrass thrive. Apply it a few weeks after planting and once a month thereafter.
  • Mulching: Add a layer of organic mulch around the base of the plant to help retain moisture, suppress weeds, and regulate soil temperature.
  • Pruning: Remove any dead or damaged leaves, and cut back the young shoots by half to encourage growth.

With good care, your newly transplanted lemongrass will thrive and reward you with its fragrant leaves and tasty stalks.
