The rosemary plant is very adaptable and can be grown in almost all areas. Basically, rosemary can be grown under dry-land conditions. However, if it is cultivated under irrigated conditions, make sure the plants are not over irrigated. During initial planting stage, this crop requires irrigation and subsequent light irrigations should be given until the crop is well-established. After establishment with strong root system, this can yield very well if  the annual rainfall is above 550 mm.

Soil Requirement for Rosemary Cultivation:- Rosemary plants thrive best in well-drained sandy loam soils. However, it can also be grown in clay loam soil which has less than 25 % of clay. The required soil pH for best yield is 5.5 to 8.9. It can’t tolerate the soils having heavy clay percentage (not more than 25%).

Land/Soil Preparation in Rosemary Cultivation:-  If you are planning for commercial large scale cultivation, it is recommended to go for soil test from which soil health can be found. Full fill all the required nutrients according to the soil test results. Adding well-decomposed organic matter will result in good yield. Avoid waterlogged and heavy clay soils as these plants cannot tolerate. Prepare the land by giving 3 to 4  deep ploughings to get the soil to fine tilth stage. Remove any weeds from previous crops. Based on the type of cultivation, fertilizers should be planned. For organic crop growing, natural remedies should be adopted where as in-organic cultivation, appropriate chemical fertilizers should be applied in the soil.

Propagation in Rosemary Cultivation:- Rosemary crop is propagated through seeds, cuttings and layering of roots.

  • Seed propagation: This type of propagation is not recommended due to slow germination of rosemary seeds and growing true-to-type plants from seed is not a good practice as there is always a problem of cross pollination.
  • Cutting Propagation: The best and efficient way to propagate rosemary plant is cuttings from growing stem tips. 12 to 15 cm length of cuttings should be collected and bottom 2/3 should be stripped from leaves then these cuttings ( 1/2 to 2/3 of length) should be inserted in a growing medium. Roots start farming after 3 to 4 weeks. For better root formation, a mist bed with a heated floor should be used.
  • Layer Propagation: This type of propagation can be achieved in summer season by pegging of some of the lower branches under a sandy soil. The plants can be served from the parent plant once roots have been formed.

Plantation in Rosemary Cultivation:- Rosemary plants require full sun light so it is advised  to have rows in east-west direction. When it comes to field spacing, beds of 1 to 2 meter and row space of 40 cm to 50 cm is more effective for machine cutting. Plants should be established at 25 cm to 50 cm within the rows so that the soil is covered quickly. When it comes to plant density, a total of 50,000 to 60,000 plants/ha is required. The rosemary cuttings can be prepared in the greenhouse or nursery and be transplanted to the main field in spring to midsummer.

Irrigation in Rosemary Cultivation:- Usually, rosemary is grown in dry-lands. However, it requires irrigation until the roots are wee-established in the soil. Don’t allow the plants to dry out and at the same times they should not be over irrigated. If the annual rainfall is more than 450 mm. it does not require any irrigation. In rainy season, make sure  the water  will not stagnate in the field and should be drained out as early as possible.

Manures and Fertilizers in Rosemary Cultivation:- Manures and fertilizers should be applied according to result of soil test.

Weed Control in Rosemary Cultivation:-  Weed control is very important in rosemary cultivation as it affects the quality and yield of  essential oil. Hand weeding and hoeing should be carried out during the weed growth. Usually 3 to 4 weedings should be required during the year. Use hand hoe for inter-row cultivation. Care must be taken not to damage the root system . Effective rosemary plant density & canopy will check the weeds growth.

Pests and Diseases in Rosemary Cultivation:- The following are the pests and diseases found in Rosemary cultivation.

  • Pests found in Rosemary Cultivation: This crop is vulnerable to spider mites, mealy bugs, whiteflies and thrips.
    • Control Measures: Careful and thorough monitoring, crop rotation as well as applying insecticidal soap with lightweight horticultural oil will help to control these pests.

    • Control Measures: Early detection and management of disease can prevent major problems in rosemary cultivation. Contact your local horticulture department for diseases identification and control measures.

Harvest in Rosemary Cultivation:-  Rosemary crop can be harvested once or twice a year depending on whether it is cultivated for plant material or essential oil. Mechanical harvesting is preferred and a fist cutting can be done in the seeding year. However it should be delayed until 18 months after seeding. The yield would be more from re-growth of the crop. If the purpose of the crop is for essential oil, the highest quality, plants should be in bloom and only the flowering tops should be harvested for distillation purpose. For the fresh market, the  rosemary herb should be harvested frequently at a young stage as young, fresh shoots are used in culinary preparations. Note that woody stems will lower the price. Fresh rosemary should be harvested early in the morning and kept cooled at 6°C before packaging for the market.

Post-Harvest in Rosemary Cultivation:Rosemary should be dried at temperatures lower than 39°C to reduce loss of flavour of essential oil and to maintain a good green colour. After drying, the leaves should be separated from the stems and graded.

Yield in Rosemary Cultivation:- Yield depends on many factors like soil, cultivar (variety) climate and cultivation practices. On an average the yield of 30 to 80 kg of essential oil can be obtained. Dried leaves of 2000 to 2200 kg/ha can be expected.

Marketing in Rosemary Cultivation:- The market for essential oils in India is divided into local buyers and international (export) buyers. Usually the local buyers include marketing agents and  chemical and pharmaceutical companies, as well as food and flavouring industries.
