A smallholder crop
Both grasses suit farms of under two hectares: low input needs, perennial regrowth, and harvests every 60–90 days that produce regular cash flow rather than one risky annual payout.

The business behind the aromatic grasses
Behind every candle and curry paste sits a global trade in grass and steam. Who grows lemongrass and citronella, who profits along the way, and what makes this niche corner of agriculture tick.
Why it matters
A quiet but meaningful agricultural trade
Lemongrass and citronella never make commodity-market headlines like coffee or palm oil, yet together they support hundreds of thousands of smallholder livelihoods across the tropics.
An industrial feedstock
The distilled oil flows into flavor houses, fragrance labs, cosmetics lines, and pesticide formulators — industries that buy by the drum and care intensely about chemical consistency.
A price-volatile niche
Raw oil prices can swing dramatically between seasons as weather, synthetic substitutes, and fashion cycles collide. Understanding volatility is essential for anyone in the chain.
Global picture
Two oils, side by side in trade
Citronella is the bigger volume crop; lemongrass commands the more stable flavor-and-wellness following. Public estimates disagree on exact totals, so treat these as orientation figures.
| Metric | Lemongrass oil | Citronella oil |
|---|---|---|
| Estimated global output | Roughly 800–1,000 tonnes per year (India's CSIR-CIMAP cites ~1,000 t) | Historically estimated in the low thousands of tonnes per year; modern tallies vary widely by source |
| Indicative trade value | ~USD 55–60 million (2024 industry estimates), projected toward ~USD 140 million by mid-2030s | Estimates span ~USD 100 million (raw oil) to USD 500 million+ when formulated products are counted |
| Leading producers | India dominates (~70–80% of export shipments), with Guatemala, China, and several Southeast Asian suppliers | Indonesia leads (Java-type), followed by China, Vietnam, Guatemala, India, and Sri Lanka |
| Main destination markets | United States, United Kingdom, Germany, Japan, Australia, Netherlands | United States and Europe — largely fragrance and repellent-product manufacturers |
| Typical raw-oil price band | ~USD 20–40/kg in recent years, with spikes well beyond during shortage years | ~USD 12–35/kg historically, among the most price-cyclical of common essential oils |
| Primary demand engines | Natural personal care, aromatherapy, food & beverage flavoring, traditional-medicine markets | Insect-repellent consumer goods, perfumery intermediates, soaps and detergents |
| Reported growth trajectory | High single digits annually (~9–10% CAGR in recent forecasts) | Moderate single digits (~5–9% CAGR depending on scope and forecaster) |
A note on the numbers
No official exchange tracks these oils the way it does coffee or sugar. Figures above blend research-institute estimates (such as India's CSIR-CIMAP), customs-data aggregators, and commercial market-research reports, current as of 2024–2026 publications. Different firms draw the market's boundary differently — raw oil only versus finished candles and sprays — which explains wildly different headline values. Always verify against current trade data before making decisions.
Production geography
Who grows the world's supply
Production clusters where labor is affordable, climates stay humid and warm, and distillation infrastructure already exists.
Lemongrass № 1Citronella
India
The lemongrass powerhouse — East Indian lemongrass (C. flexuosus) grown across Kerala, Karnataka, Assam, and Uttar Pradesh feeds most of the world's lemongrass oil exports. India also produces citronella and, through CSIR-CIMAP, drives much of the published agronomy and yield research.
Citronella № 1Lemongrass
Indonesia
Home turf of Java citronella (C. winterianus) and the world's largest citronella oil supplier, centered in Java and Sumatra with a deep base of village-level stills and established exporters serving fragrance houses worldwide.
CitronellaLemongrass
China & Vietnam
Sizable citronella output and fast-growing lemongrass cultivation, often integrated with domestic herbal-industry processing. Vietnam has expanded steadily into both oils as regional demand grows.
LemongrassCitronella
Guatemala & Central America
A long-standing Western-hemisphere supplier of both oils, shipping into North American and European buyers seeking origins outside Asian monsoon risk.
Citronella
Sri Lanka
The birthplace of Ceylon citronella (C. nardus). Output today is modest compared with the Java-type giants, but the origin retains a reputation niche in specialty fragrance circles.
Fresh stalks
Fresh-market growers everywhere
Beyond the oil trade, fresh lemongrass for kitchens is grown commercially in Thailand, Vietnam, the Philippines, and increasingly in temperate-greenhouse operations near diaspora grocery markets.
Follow the money
The value chain: grass to shopping cart
Value multiplies at every step away from the field. A kilogram of oil bought from a farmer for tens of dollars may leave a factory as hundreds of dollars of candles, soap, or flavorings.
How the crop physically makes this journey → post-harvest guide- Grower
Typically a smallholder farming 0.5–2 ha. Sells cut grass to a local still, or distills cooperatively. Earns the thinnest slice of final retail value.
- Distiller
Village-scale or commercial units convert 100 kg of grass into roughly 0.5–1 kg of oil. Access to an efficient still dramatically changes farm income.
- Trader / exporter
Bulks drums from many villages, tests chemistry (citral or citronellal content via gas chromatography), grades, and ships in 180 kg steel drums.
- Flavor & fragrance house
Purifies, fractionates, and blends. Citronella oil becomes isolated citronellal and geraniol building blocks for dozens of downstream aroma chemicals.
- Consumer brands & retailers
Candles, sprays, teas, shampoos, cleaners. Here a few grams of oil inside a single retail item can outprice the entire kilogram cost of the raw material.
Farm-level view
What one hectare can earn
An illustrative budget for a managed hectare of lemongrass or citronella in the humid tropics. Real outcomes vary enormously with region, prices, and whether the farmer controls a still.
| Item | Illustrative figure | Notes |
|---|---|---|
| Establishment | Slips/divisions for ~1 ha, planted at the rains' start | Mainly a first-year cost; clumps remain productive 4–6 years |
| Harvest cycle | First cuts from month 6–8; then every 60–90 days | 3–5 cuts per year depending on climate and vigor |
| Annual grass yield | ~10–20 tonnes fresh grass | Citronella often yields more biomass than culinary lemongrass |
| Oil recovery | 0.5–1% of fresh weight → roughly 60–120 kg oil | Efficiency hinges on still quality, wilting, and cut timing |
| Selling as grass | Lowest margin; buyer bears distillation upside | Common where farmers lack capital for stills |
| Selling as oil | Tens of dollars per kg × 60–120 kg — the real income lever | Cooperative stills let villages keep this step's margin locally |
| Premium niches | Organic certification adds ~20–50% price premiums | Offset by certification cost and 2–3 year transition period |
Why distillation access decides incomes
The spread between selling wet grass and selling distilled oil is frequently the difference between marginal and decent returns. Wherever development agencies fund village stills, farmer incomes rise without planting a single extra slip.
Not investment advice
This table teaches structure, not guarantees. Yields collapse under drought; prices crash when synthetics undercut naturals; and local factors dominate. Anyone considering commercial planting should model costs against current, verified local prices.

Reading the market
What moves prices & where the industry is heading
Four forces set the tone in any given year — and two long-term currents shape the decade.
Typical export price bands, USD per kg (FOB)
FOB mid-range prices, 2019–2025 (USD per kg)
Short-term price drivers
- Monsoon & cyclone luck: drought or floods in Java or Kerala ripple straight into global quotes
- Synthetic citral & citronellal: cheap petro-derived substitutes cap how high natural oil can climb
- Chemistry grading: buyers pay by GC profile, so a high-citral lot earns a premium over average grass from the same region
- Demand shocks: the pandemic-era disinfectant surge briefly sent both oils soaring; fashion cycles repeat
- Currency swings: rupee, rupiah, and dollar movements reshape exporter margins overnight
- What does not move prices much: garden-center "citronella plant" hype, home-distillation trends, social-media wellness waves
Tailwind: natural everything
Clean-label food, botanical personal care, and biopesticide-friendly regulation all favor plant-derived actives. Organic-certified lots routinely command 20–50% premiums, and traceable fair-trade sourcing programs are spreading from coffee into essential oils.
Headwind: synthetics & consolidation
Laboratory-made linalool, citronellal, and citral keep improving while getting cheaper, squeezing the floor under natural oil. Meanwhile, buying consolidates into fewer multinational flavor-fragrance houses with stronger bargaining power over dispersed smallholders.
Watchlist for the next decade
Climate stress on monsoon-dependent growing belts; certification and traceability tech reaching village level; new origin countries (East Africa, Latin America) courting buyers; and continued double-digit growth in aromatherapy-driven lemongrass demand versus steadier citronella volumes tied to repellent seasons.
Market FAQ
Economics questions, answered plainly
Why do market-size figures for these oils differ so much between reports?
Boundary definitions. Some analysts count only bulk raw oil traded in drums — a market measured in the tens to low hundreds of millions of dollars. Others roll in finished candles, sprays, soaps, and teas that contain the oil, multiplying the headline severalfold. Neither is wrong; they're measuring different things. Compare figures only when the scope matches.
Is citronella or lemongrass the bigger business?
By volume, citronella: it's been the workhorse of the insect-repellent and soap industries for a century, with output historically several times larger than lemongrass oil. By growth rate and price stability, lemongrass currently has the edge thanks to booming natural-personal-care and food-flavoring demand.
Can a small farmer realistically profit from these crops?
Many thousands already do — the crop suits smallholders precisely because inputs are low and harvests recur. Profitability usually hinges on two things: proximity to an efficient distillery, and timing sales against price cycles. Farmers who organize into cooperatives to control distillation and aggregate drums consistently capture more of the chain's value.
Where does the biggest markup happen?
Downstream. Formulators and retailers transform dollars-per-kilogram oil into dollars-per-unit retail goods. A citronella candle holding perhaps ten grams of oil sells for more than a farmer received for the entire kilogram of oil inside a batch. That asymmetry is exactly why origin-country processors try to move up the chain into semi-finished aroma chemicals.
Do organic premiums apply to these oils?
Yes — industry sourcing guides report certified-organic essential oils earning roughly 20–50% over conventional equivalents. The catch is the transition: two to three years of certification during which yields and prices don't yet reflect the effort, plus audit costs that bite hardest at small scale. Group certification schemes soften the burden.
