Lemongrass Cultivation: Slips Planting, Distillation, and Market Reality

Lemongrass cultivation has gained significant traction across dryland areas in India due to its ability to thrive on marginal soils with minimal water. This aromatic grass produces an essential oil rich in citral, which is widely used in perfumes, soaps, detergents, cosmetics, and insect repellents. For farmers with underutilized land or limited water resources, lemongrass represents a reliable cash crop that offers steady income for several years. However, unlike common field crops, lemongrass cannot be harvested and sold directly in the local mandi. The real product is the essential oil, which must be extracted on or near the farm through steam distillation. This makes it an agro-industrial venture rather than a simple farming activity. To succeed, you need to understand the plantation process, the operation of distillation units, and how to access genuine buyers while avoiding common promotional traps.

Suitable Climate and Soil for Lemongrass

Lemongrass is a sturdy perennial grass that grows best in tropical and subtropical regions. It requires warm temperatures ranging from twenty-five to thirty-eight degrees Celsius and abundant sunlight. If grown in shady areas, the grass will grow tall but the concentration of citral in the leaves will drop significantly. It can survive in areas with low rainfall, but regular watering is needed to achieve multiple grass cuts per year. The plant is highly resilient to dry spells, making it suitable for regions prone to erratic monsoons.

In terms of soil, lemongrass is highly adaptable and can grow on poor, marginal soils where other crops fail. However, for commercial success, well-drained sandy loam soil with a pH between five point five and seven point five is ideal. The plant is sensitive to waterlogging. High clay soil that stays saturated will rot the roots and kill the clumps. If you have clay soil, planting on ridges or raised beds with clear drainage paths is highly recommended.

Why Slips are Preferred Over Seeds for Planting

Although lemongrass can produce seeds, commercial farmers rarely use them. Lemongrass seeds have low germination rates and tend to produce genetically variable plants. Many seed-grown plants end up having low oil content or low citral levels. Therefore, vegetative propagation using slips is the industry standard. A slip is a shoot separated from a mature lemongrass clump, with its roots trimmed and top leaves cut back.

Sourcing slips from a high-yielding, verified variety like Krishna, Cauvery, or Praman is essential. You need about twenty-five thousand to thirty thousand slips to plant one hectare of land. Using slips guarantees that every plant in your field is genetically identical to the parent plant, ensuring consistent oil quality and yield. It also speeds up the establishment of the crop compared to nursery seedlings.

Field Preparation and Planting Slips

Prepare the field by plowing it twice or thrice to clear weeds and loosen the soil. Incorporate about ten tonnes of compost per hectare during the final plowing. Planting is best done during the onset of the monsoon in June or July. Dig small holes at a spacing of sixty centimeters by forty-five centimeters or sixty centimeters by sixty centimeters, depending on soil fertility and machinery access.

Insert one or two slips into each hole, pressing the soil firmly around the base to hold them upright. Plant the slips at a depth of five to eight centimeters. Irrigation should be applied immediately after planting if there is no rain. The slips will establish new roots and start shooting new leaves within ten to fifteen days. Ensure the soil remains moist but not waterlogged during this initial rooting phase.

Irrigation Methods and Water Management

While lemongrass is drought-tolerant, its oil yield is directly linked to soil moisture. During the dry summer months, irrigate the field every ten to twelve days. In winter, water every fifteen to twenty days. If you rely entirely on rain, the grass will only yield two cuts a year, whereas irrigated fields can yield four to five cuts annually.

Drip irrigation is highly effective as it delivers water directly to the root zone, reducing weed growth in the inter-row spaces. It also optimizes water use efficiency in dry regions. Check your irrigation needs using the irrigation calculator. Regular moisture monitoring prevents the crop from entering dormant states during peak summer, ensuring continuous leaf growth.

Nutrient Management for High Biomass

Lemongrass is a heavy feeder because you remove the entire foliage during every harvest. Soil nutrients must be replenished to maintain high yields. Apply a balanced fertilizer dose of one hundred kilograms of Nitrogen, fifty kilograms of Phosphorus, and fifty kilograms of Potassium per hectare per year. Apply all the Phosphorus and Potassium as a basal dose during planting.

Apply the Nitrogen in four to five split doses, ideally after each grass cut. This stimulates rapid regrowth of new shoots. For organic farms, apply fifteen tonnes of farmyard manure or five tonnes of vermicompost per year. You can compute the exact nutrient requirement using the fertilizer calculator. Regular soil testing helps prevent micro-nutrient deficiencies.

Weed Management and Canopy Development

Weeds are a major problem in the first three months after planting before the lemongrass clumps grow large enough to shade the ground. Perform the first weeding and hoeing thirty days after planting, and a second one at sixty days. Once the clumps form a dense canopy, they will smother most weeds, reducing labor costs in subsequent years.

Do not use chemical herbicides, as residues can contaminate the essential oil and lead to rejection by buyers. Instead, rely on manual weeding or light tractor-drawn weeding implements between the rows. Keeping the early field clean allows the slips to establish their root system without competing for soil nutrients.

Pest and Disease Management in Lemongrass

Lemongrass is relatively free from major pests because of its strong oil odor, which acts as a natural deterrent. However, stem borers occasionally attack the base of the stalks, causing the central leaf to dry up. You can manage stem borers by spraying neem seed kernel extract or removing affected clumps. Fungal leaf blight and rust can occur during warm, humid monsoon weeks.

Avoid planting too close together, as good air circulation is the best way to prevent fungal diseases. If you observe rust spots on the leaves, harvest the crop early to prevent the disease from spreading and to save the foliage biomass. Never apply synthetic chemical fungicides close to the harvest window.

Harvesting Cycles and Cutting Schedules

The first harvest of lemongrass is ready about ninety to one hundred and twenty days after planting. Subsequent harvests can be taken every sixty to seventy-five days. Cut the grass ten to fifteen centimeters above the ground level using sharp sickles. Do not cut too close to the ground, as this can damage the growing buds and delay regrowth.

A single lemongrass plantation can remain productive for four to five years, after which the oil yield begins to decline, and the field needs to be replanted. After cutting the grass, let it wilt in the shade for twenty-four hours to reduce moisture. Wilting prevents mold and reduces the volume of grass, making distillation more efficient.

Setting Up an On-Farm Distillation Unit

You cannot sell raw lemongrass in local vegetable mandis. To make a profit, you must extract the essential oil using a steam distillation unit. A basic unit consists of a distillation vessel, a condenser, and a separator. The wilted grass is packed tightly into the vessel, and steam is passed through it to extract the oil.

Setting up a stainless steel distillation unit with a capacity of one tonne per batch costs approximately three to four lakh rupees. If you have a small farm, you can rent a nearby distillation unit or share the cost with a group of local farmers. The oil yield is about zero point eight to one percent of the fresh grass weight, meaning one tonne of grass yields eight to ten kilograms of oil.

The Reality of Contract Farming and Buyback Scams

Many promoters lure farmers into lemongrass cultivation by promising high oil prices and offering buyback contracts. They often charge exorbitant prices for planting slips and seedling materials, claiming they are special hybrid varieties. Once the farmer harvests the grass and distills the oil, the promoter often refuses to buy the oil, citing poor quality, or vanishes entirely.

Never rely on verbal buyback promises. Before buying slips, find verified chemical manufacturers or aroma houses and sign direct supply contracts with them. Consult your local agriculture officer or Krishi Vigyan Kendra to verify the credentials of any contract farming promoter. Keep your financial dealings transparent and avoid paying large registration fees.

Project Economics and Realistic Returns

The cost of establishing one hectare of lemongrass, including slips, land preparation, fertilizers, and labor, is about fifty thousand to sixty thousand rupees in the first year. Maintenance costs in the second, third, and fourth years are lower, around twenty thousand rupees per year. A well-managed hectare yields about eighty to one hundred and twenty kilograms of lemongrass oil per year.

At a market price of one thousand to fifteen hundred rupees per kilogram of oil, the gross annual revenue is eighty thousand to one lakh eighty thousand rupees. After deducting operational costs, the net profit is sixty thousand to one lakh twenty thousand rupees per year. However, if you must pay for your own distillation unit, the payback period will be longer. All figures are indicative.

Marketing Channels for Lemongrass Oil

Lemongrass oil is widely used in soaps, detergents, cosmetics, and insect repellents. Major buyers include fragrance manufacturers, chemical companies, and cosmetic brands. You can find buyers through online trade portals or by contacting perfume manufacturers in cities like Kannauj, Mumbai, or Delhi. Always get a sample of your oil tested for citral content, as oil with more than eighty percent citral commands a premium price.

If you are based in West Bengal, note that the state offers the premium-free Bangla Shasya Bima scheme for specific crops. While this covers food and oilseeds, check local district updates to see if aromatic crops have been included. For other states, look for central insurance schemes or cooperative structures to safeguard your aromatic plantation.

Investing in a high-efficiency steam distillation unit can also increase your profit margin. Standard direct-fired units often burn the grass or yield low-quality oil with lower citral content. Modern boiler-operated steam distillation plants extract a higher percentage of oil and preserve the light yellow color that premium buyers look for. Sharing the cost of a distillation unit with neighboring farmers through an FPO is an excellent way to reduce individual capital investment.

Before harvesting, ensure that the cutting tools are sharp to make clean cuts. Cutting the grass about 10 to 15 centimeters above the ground encourages rapid shoots regrowth for the next cutting. Avoid harvesting during cloudy or rainy days, as the essential oil concentration in the grass drops during wet weather, resulting in lower oil yields at the distillation plant.

In addition, allow the cut grass to wilt in the shade for 24 hours to reduce its moisture content. This simple step decreases the weight of the grass by twenty percent, making it easier to transport and allowing for more grass to be packed into the distillation tub, which improves the extraction efficiency and saves fuel costs during the heating process.

To maintain soil fertility over the five-year plantation life, return the spent grass (distilled waste) to the field as compost. Spent lemongrass grass is rich in silica and organic carbon, and applying it between the rows improves the soil moisture retention and organic matter content, helping the clump regenerate faster after each harvest. This recycling of organic biomass reduces your dependence on chemical fertilisers.

For transport, ensure the essential oil is stored in clean, airtight containers made of food-grade aluminum or galvanized iron. Exposure to air, light, or rust will oxidize the oil and lower its citral content, which severely decreases its market value and could lead to rejection by exporters.
