Palmarosa plant: information on amateur and income cultivation, properties, botanical species and essential oil production.
Therepalmarosait's aplantbelonging to the genusCymbopogon,the same as thelemongrass: it is no coincidence, therefore, that thepalmarosa plantsare similar to those oflemongrass, also known as lemon grass.
The botanical name of thepalmarosais Cymbopogon martinii while as seen in the article dedicated to the Properties of Citronella, the name lemon grass refers to the species Cymbopogon Nardus.
Therepalmarosa plantit is also known by the common names ofIndian geranium, Ginger grassisRosha. It's about a plant originally from India and Indochina but which is cultivated all over the world for its aromatic properties.
To make thePalmarosa plantis its essential oil. Since these are two not too distant relatives, it is no coincidence that the properties of the essential oil of Palmarosa are similar to those of the essential oil of lemongrass; unlike lemongrass essential oil, the one extracted frompalmarosa plantit has a more floral scent, similar to that of roses, which is why it is used in the cosmetics industry for the production of scented creams and soaps.
Palmarosa essential oil is rich ingeraniol, appreciated for its perfume and for its many uses in traditional medicine. The essential oil produced by palmarosa planthas proven to be an effective anti-insect repellent so much so that it is used as a natural remedy to ward off insects that feed on wheat, it also has strong antifungal properties (to eradicate fungal diseases). It is a good oneanthelminticagainst nematodes and like lemongrass it is a good natural repellent against mosquitoes. This essential oil is produced by a steam distillation process starting from the leaves of thepalmarosa plant.
Cultivation of the palmarosa plant
Therepalmarosait's aplantvery hardy that grows well at different altitudes or directly above sea level. It thrives best if grown in full sun, does not tolerate waterlogging and does not resist in full shade. Therepalmarosait prefers well-drained soils, with a neutral or alkaline reaction (soil pH around 7 or slightly higher). It can also be grown near the sea as it resists saline soil well. Among the best varieties we point out theTrishna, developed by cross-breeding of four elite varieties for the production of essential oil. Therepalmarosavar. Trishna has a geraniol content of 93% and a yield in terms of essential oil produced over 40% compared to other varieties.
The cultivation of palmarosa as a source of income
Who intendscultivate the palmarosain the home, it can start from the seed and transplant when the plant has reached a height of about 15 cm. For the cultivation of palmarosa on a farm (perhaps for the production of essential oils) it will be necessary to use 2.5 kg of seeds for each hectare to be cultivated.
The field must be prepared with a preliminary plowing. The furrows must be 90 cm away from each other and in the same row the distance of 60 cm between one plant and another must be respected.
For the production of palmarosa essential oil it is recommended to collect the leaves at the beginning of flowering. If it is harvested in full bloom, the yield in terms of essential oil produced will be greater but it will be at the expense of quality as the essential oil obtained will be less fragrant.
Within the company, one hectare of land cultivated withplants of palmarosaprovides from 15 to 20 tons of herb with an essential oil yield of 50 - 60 kg per year. The production of palmarosa essential oil starting from the steam distillation of the leaves would seem the most effective method of extraction. A plantation ofpalmarosait can be kept for about 8 - 10 years but the yield in terms of essential oil produced begins to decline from the fifth year. The residues of steam distillation are used as organic matter in the production of compost and fertilizers.
