The rosemary is considered as a potentially invasive species in some parts of the world. The seeds are often difficult to germinate. The seeds have very low germination rate and the seedlings generally grow slowly. But the plants can live for many years, as long as 30 years.

Leaves of the rosemary plants are evergreen, 2-4 cm long and 2-5 mm broad. The leaves are green above and white below with dense, short and wooly hair.

Propagation of the rosemary plants is done in many different ways. Generally the plants are propagated through seeds, cuttings and layering of roots.

Cutting Propagation

The best and most efficient way to propagate rosemary plant is cuttings from growing stem tips. Collect cuttings of 12 to 15 cm length and the bottom 2/3 should be stripped from leaves.

And then insert the cuttings in a growing medium. Roots will start forming after 3 to 4 weeks. Use a mist bed with a heated floor for better root formation.

Layer Propagation

Layer 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.

Seed Propagation

Seed propagation is not recommended for commercial rosemary farming business. Because the seeds are very slow to germinate and the growth rate of the seedlings is also very slow.

And growing true-to-type plants from seed is not a good practice as there is a problem of cross pollination.

Purchase Plants

If you want to avoid the hassle of propagation of rosemary, then you can purchase ready seedlings from any of the nurseries in your area.


The rosemary plants generally require full sun for better growth. Space of the beds should be 1-2 meter and raw space should be 40 to 50 cm. This spacing is very effective for machine cutting.

A total of 50,000 to 60,000 plants is required per hectare. Water the plants immediately after planting in the main field.


The rosemary plants are very strong and hardy. So, they generally require less caring and other management. Although, taking additional care will help the plants to grow well and stay healthy.


Add adequate organic fertilizers during preparing the soil for rosemary farming. And additional application of fertilizers should be done depending on soil test.


Rosemary plants generally grow well in dry-lands. Although, irrigation is required for commercial rosemary production until the roots are well established in the soil.

Don’t allow the plants to dry out and at the same time the plants should not be over irrigated. The plants don’t require any irrigation if the annual rainfall is more than 450 mm.


Mulching is very important for rosemary farming. Mulching not only helps to retain moisture into the soil but also helps to prevent weeds. You can use organic materials for mulching.

Controlling Weeds

Controlling weeds is also very important, because weeds consume nutrients from soil and the rosemary will suffer. Regular hand weeding and hoeing will help you to reduce most of the weeds.

Pests & Diseases

Like many other commercial crops the rosemary plants are also susceptible to some common pests and diseases.

Spider mites, mealy bugs thrips and whiteflies are common pests of the rosemary plants. Applying of insecticidal soap with lightweight horticultural oil will help to control these pests.

Powdery mildew, root rot and fungal problems are the common diseases of the rosemary plants. Contact your local horticulture department for diseases identification and control measures.


Rosemary crop can be harvested once or twice a year depending on whether it is cultivated for plant material or essential oil.

Rosemary leaves are harvested with the onset of flowering. The flowering tops are harvested with a sickle (30-35 cm long with leaves).

Mechanical harvesting is preferred and a first cutting can be done in the seeding year. However, it should be delayed until 18 months after seeding.

The yield will be more after first cutting from re-growth of the crop. The highest quality flowering tops should be harvested for distillation purpose if you want to produce essential oil.

The rosemary herb should be harvested frequently at a young stage for marketing fresh rosemary. The fresh shoots are generally used in culinary preparations.

Post-Harvesting Tasks

Rosemary should be dried at temperatures lower than 39° C to reduce loss of flavor of essential oil and also to maintain a good green color. And then the leaves should be separated from the stems and graded after drying.


Telling the exact amount is very tough, because it depends on numerous factors. It depends on common factors like soil, cultivar, climate and also cultivation practices. But you can expect an average yield of 30 to 80 kg of essential oil per hectare and 2000 to 2200 kg of dried leaves.


For marketing, you can either target your local market or consider exporting to international buyers. You should determine your marketing strategies first before starting this business.

These are the common steps and ways for starting and operating a successful rosemary farming business. Hope this guide has helped you! Good luck and may God bless you!
