- Soil should be porous. Water should not stagnate.
- Water retention of soil should be low, clay soil is not suitable.
- Rains should be around 150-200cm per year.
- Grows best in alkaline soil.
2. Sowing period
- Take 1kg of seeds for 1 acre i.e 2.5kg for 1 hectare.
- 1kg of seeds with the best variety costs around 3000 rupees. ($40)
- Make a raised bed to sow the seeds.
- Sow the seeds in the month of April-May.
- After 45 days of sowing, the plants would be around 15 cm in height. ( in the month of June-July)
- Transplant the plants to the mainland at a distance of 45*30 cm
- Once transplanted, water the plants to avoid drying up.
- If you are dependent on rains for the water, then sow the plants +during the rainy season. Plan accordingly.
- If you are sowing seeds directly to the mainland, then sow them during June-August.
- Around 30,000 slips required to cover 1 acre of land.
3. Irrigation for Palmarosa cultivation
- Water the plants once in 10-15 days.
- It requires a low amount of water.
- Suitable for dry areas and water shortage areas.
- It requires a lot of sunshine, and less rain around 150-200cm per year.
4. Weeding procedure in Palmarosa cultivation
- Initially after transplanting once or twice before the first harvest.
- Later weeding should be done, after every harvest.
5. Harvesting Palmarosa
- The complete crop above the ground can be used to extract the essential oil.
- The percentage of Geraniol will be high in flowers. The quality of Palmarosa oil is determined by the percentage of Geraniol.
- Harvest the crop from 10 to 15 cm above the ground. Leaving the plant to regrow.
- The first harvest is after 5months (During the flowering time before seed creation)
- Successive harvests will be after every 2.5 months for the next 5 years.
- Harvesting to be done only if you see the flowering. Geraniol content will be high during flowering.
- Before flowering and after flowering is complete, the Geraniol content will drop.
- 4-ton herbage from an acre per harvest can be expected. (4 ton/acre/harvest)
- There are 4 harvests per year.
- In total 16 ton per acre in a year.
6. Palmarosa’s Essential Oil extraction

- So per acre in a year around 60 – 80 kg of essential Palmarosa oil can be extracted.
Palmarosa plant varieties
There are varieties of Palmarosa plant which differs in herbage quantity and Geraniol content, some are developed by research centers in India. Here are the best varieties available in the market.
|Palmarosa Varieties||Oil extracted (kg/acre/year)||Geraniol(%)|
GC report for Palmarosa Essential Oil
Gas chromatography (GC) is a common type of chromatography used in analytical chemistry for separating and analyzing compounds that can be vaporized without decomposition. There should be a peak for Geraniol, this determines the quality of Palmarosa Oil quality. The purity oil determines the rate in the market. After every oil extraction process, the GC certificate is a must for that batch, to command a better price.
