Lemon Grass Nutrition Requirements

Nutrition required by Lemon Grass at each stage of its life cycle.

Soil Preparation

Soil preparation is crucial for growing healthy and productive lemon grass (Cymbopogon citratus) plants.

Here's a guide to soil preparation methods and nutrition requirements at the soil preparation stage for lemon grass:


Soil Preparation Method:


1. **Site Selection:**

Choose a well-drained location with full sunlight for planting lemon grass.


2. **Soil Testing:**

Conduct a soil test to assess soil pH and nutrient levels. Lemon grass prefers slightly acidic to neutral soil with a pH of 6.0 to 7.5.


3. **Weed Removal:**

Remove any weeds or vegetation from the planting area to reduce competition for nutrients and water.


4. **Soil Aeration:**

Use a garden fork or tiller to loosen the soil to a depth of about 8 to 10 inches. This helps improve soil aeration and drainage.


5. **Soil Amendments:**

Incorporate organic matter such as compost or well-rotted manure into the soil to improve soil structure, fertility, and water retention.


6. **Leveling:**

Level the soil surface using a rake to create a smooth planting bed.


Nutrition Requirement at Soil Preparation Stage:


1. **Nitrogen (N):**

Lemon grass requires nitrogen for vegetative growth and leaf development. Incorporate nitrogen-rich organic amendments such as compost or aged manure into the soil.


2. **Phosphorus (P):**

Phosphorus promotes root development and overall plant growth. If the soil test indicates low phosphorus levels, add a phosphorus-rich fertilizer according to the recommended application rate.


3. **Potassium (K):**

Potassium is essential for plant vigor and stress tolerance. Incorporate potassium-rich organic amendments such as wood ash or potassium sulfate into the soil if needed.


4. **Micronutrients:**

Lemon grass may benefit from micronutrient supplementation if the soil test reveals deficiencies. Consider adding a balanced micronutrient fertilizer or foliar spray containing iron, manganese, zinc, and other trace elements.


It's essential to maintain soil fertility and nutrient levels throughout the growing season by applying additional fertilizers or organic amendments as needed. Regular soil testing and monitoring plant health can help determine specific nutrient requirements and adjust fertilization practices accordingly. Additionally, mulching the soil surface with organic materials can help conserve moisture, suppress weeds, and provide slow-release nutrients as the mulch decomposes. With proper soil preparation and nutrient management, lemon grass can thrive and produce abundant foliage for culinary and medicinal purposes.
