I. The Benefits of Rosemary

1. Culinary use

The tender leaves of rosemary can be used directly in cold dishes, and as a seasoning for stews, soups, and meat. It can also be used for grilling meat. It is an important component of mixed spices. It is commonly used in Italian cuisine and French cuisine.

2. Medicinal use

Rosemary is a medicinal plant of the Lamiaceae family, with the whole herb used as medicine. Traditional Chinese medicine holds that rosemary is warm in nature and pungent in taste, with effects such as aromatic stomach-strengthening and calming the nerves, and is commonly used to treat various headaches, neurasthenia, and so on. In recent years, research at home and abroad has proven that rosemary also has many medical and health functions, such as a strong inhibitory and killing effect on Staphylococcus aureus, Escherichia coli, and so on; treating oligomenorrhea, amenorrhea, or irregular menstruation caused by neurological and hormonal disorders in menopausal women, promoting menstruation or regulating menstruation; strengthening the inhibition process of the cerebral cortex, with good sedative, hypnotic, and anticonvulsant effects; regulating blood pressure, restoring low blood pressure to normal; reducing capillary permeability, promoting hair regrowth and preventing early hair loss; relieving asthma and coughing, treating asthma attacks and chronic bronchitis; as a cardiotonic, used for cardiac neurosis such as palpitations; used to treat intestinal infections and diarrhea; promoting blood circulation, reducing muscle pain, and refreshing the mind and enhancing memory. However, rosemary is not suitable for patients with high blood pressure or pregnant women.

3. Industrial use

Rosemary essential oil is a traditional European spice with high economic value. Its characteristic aroma is a blended aroma of components such as borneol, bornyl acetate, camphor, and 1,8-cineole. It is widely used in perfumes, bath lotions, cosmetics, aftershaves, soaps, and air fresheners. In addition, it has a strong insect-repellent and bactericidal effect, and is also a good natural preservative.

4. In landscaping

In the south it can be used as a hedge. It can also grow on dry rocky beaches, and is a landscaping plant with strong resistance.

II. Propagation Methods of Rosemary

1. Seed propagation

Seedlings are generally raised in a greenhouse in early spring. Both traditional soil seedling raising and plug tray seedling raising can be used. Traditional soil seedling raising requires preparing the seedbed first. The seedbed can be a flat bed or a small raised bed. The bed soil should be broken up and leveled, with sufficient fermented base fertilizer applied and sufficient bottom water watered. Broadcasting or drilling can both be used. However, the seeds should be sown as thinly as possible, or mixed evenly with fine dry soil, sown on the seedbed, and lightly watered so that the seeds make full contact with the soil. The seeds are light-loving, so sow the seeds directly on the medium without covering, and build a small arched shed over the bed, which both ensures ground temperature and keeps the soil surface from easily crusting. The seeds develop relying on the bottom water of the seedbed, but the soil surface must always be kept moist. Wait until the sprouts emerge from the soil, then water, following the principle of frequent light watering. The suitable temperature for seed germination is 15-20°C, and germination takes about 2-3 weeks. When the seedlings grow to about 10 cm, about 70 days, they can be planted out. For plug tray seedling raising, mix peat and vermiculite in a 3:1 ratio, and then sow. Cover with a thin layer of vermiculite and water thoroughly once. Build a small arched shed on top, and the subsequent management is the same as traditional soil seedling raising. The difference is that after rosemary seedlings emerge, the plug trays must be moved frequently, to prevent the roots from following the holes at the bottom of the plug tray and piercing into the ground, damaging the roots at planting time. If the plug trays are placed on shelves, there is no such need. The germination rate of rosemary is very low, generally only 10%-20%, and in the first year, rosemary grows extremely slowly. Even by autumn, the plant size is not much larger than at the time of planting out, and it takes 2-3 years to form a large yield, which is very slow. Therefore, vegetative propagation methods are generally used in production. However, plants grown from seed have a more fragrant scent, so which propagation method to use depends on the need.

2. Cutting propagation

Mostly carried out from winter to early spring. Select fresh, healthy stems that have not yet fully lignified as cuttings, cut from about 10-15 cm from the top, remove about 1/3 of the leaves from the lower part of the branch, and insert directly into the medium. Keep the medium moist. Roots will form in about 3-4 weeks, and after 7 weeks they can be planted out in the open field. The minimum night temperature for cuttings is 13°C.

3. Layering propagation

Taking advantage of the characteristic that rosemary stems can produce adventitious roots, bend branches close to the ground of the plant, cover them with soil, and leave the top in the air. Wait until new roots grow, then cut from the parent plant to form a new individual, and plant it out in the open field.

The benefits of rosemary can be said to be very broad. Growing a pot of rosemary at home not only beautifies the environment and purifies the air, but can also be used in cooking to help enrich dishes. Its uses can be said to be very broad. If you have the time and energy and are also interested, you might as well grow a pot of rosemary at home to add some enjoyment to life.

How to Grow Rosemary, Rosemary Cultivation and Propagation Methods

Rosemary likes a warm and humid environment. When the temperature is relatively high, it grows slowly, and in winter when the weather is clear and there is no cold wave, it grows relatively fast. Rosemary has many leaves, which are leathery, so it is relatively drought-tolerant, and keeping the soil slightly moist can meet its water needs. However, the soil for planting should be chosen with good drainage, which is more conducive to its growth.

Rosemary is a type of herb, likes a cool and dry environment, and the flower pot is very important for its growth. Unglazed clay pots have the best breathability and can be given priority consideration. As for the size of the flower pot, one about 20 cm in diameter is enough. If it is too large, the amount of watering is hard to control, and since rosemary grows slowly, it does not need too much growing space.

As for soil, ordinary garden soil is enough. Before planting, add a small amount of fertilizer to the soil.

Fertilizing two or three times a year is enough. Use fully decomposed organic fertilizer and place it in the soil at the edge of the flower pot. Light fertilizer applied frequently is also fine, and the amount of fertilizer used at one time does not need to be too much. Specifically, fertilize appropriately according to the growth condition of the plant.

As for watering, more watering is needed in summer. Generally, when the temperature is high in summer, do not water at noon; water once each in the morning and evening. In other seasons, generally water once a week. During maintenance, water according to the condition of the potting soil; if it is dry and whitish, it needs watering.

Rosemary is a relatively cold-tolerant plant. In winter it can be placed on a semi-enclosed balcony to overwinter, and around -5°C is no problem. So in winter there is no need to take warming measures and it still will not freeze to death. But if the winter temperature in your area is below -10°C, it is still recommended to move it indoors! In summer, when the temperature is relatively high, ventilate and cool it down in time to promote its growth.

Actually, flower lovers all water based on experience. Beginners growing rosemary need to note that in summer high temperatures, although more watering is needed, you cannot water heavily, as the plant easily wilts and its growth slows. In addition, perennial plants can also show such conditions with improper watering.

After rosemary blooms, a sufficient amount of fertilizer needs to be applied to promote long-lasting blooming, but it is best not to use chemical fertilizers, to avoid the phenomenon of burning the seedlings. For ordinary home growing, you can also water with a little fermented rice-washing water.

In humid environments, root rot, gray mold, and so on are common diseases of rosemary. If the rosemary plant wilts while the growing medium is still moist, the plant needs to be moved out of the greenhouse immediately. The most common pests are red spider mites and whiteflies. At present, the most ideal method is to use biological control.

Propagation methods suitable for rosemary include sowing, cuttings, layering, and so on. Rosemary seeds germinate slowly and have a low germination rate, so they are usually only used when introducing new varieties. During the rooting period, the suitable temperature in the greenhouse is 22°C, and the cuttings need to be misted frequently, but excessive moisture will cause the tops of the cuttings to rot, and the roots produced will not be robust enough. In the first 10 to 14 days, the cuttings begin to root, and special attention must be paid to preventing the cuttings from wilting.
