What are the cultivation methods and precautions for rosemary
Rosemary prefers a cool, dry environment with plenty of sunlight, can tolerate temperatures as low as minus 5 degrees, and can overwinter outdoors in the south. However, in extremely cold regions, measures must be taken to keep warm. In the summer, with higher temperatures, it is necessary to ventilate and cool down. It is suitable to plant in well-drained, organic-rich sandy soil and can be placed in a sunny location for maintenance throughout the year. After flowering, a dilute fertilizer can be applied.
Growth habits of rosemary
Rosemary belongs to the dicotyledonous plants, the Labiatae family, and the rosemary genus. Common propagation methods include seed propagation, cutting propagation, and layering propagation, with layering propagation being the most commonly used.
The main varieties of rosemary include: upright white flower rosemary, creeping rosemary, Australian rosemary, needle-like rosemary, upright pink flower rosemary, spotted leaf rosemary, report tree rosemary, golden rosemary, narrow-leaf upright rosemary, upright broad-leaf rex rosemary, and blue child rosemary.
Cultivation methods for rosemary
Rosemary prefers a cool, dry environment with plenty of sunlight. The choice of flower pot is important, with unglazed clay pots being the best for breathability and drainage. A pot diameter of about 20 centimeters is sufficient. If too large, it is difficult to control the amount of watering, and since rosemary grows slowly, the pot should not be too large.
Rosemary is relatively cold-tolerant and can endure temperatures as low as minus 5 degrees. It can overwinter outdoors in the south, but in extremely cold regions, measures must be taken to keep warm. In the summer, with high temperatures, it is necessary to ventilate and cool down to promote growth. It is suitable to plant in well-drained, organic-rich sandy soil and can be placed in a sunny location for maintenance throughout the year.
Watering method
Rosemary requires frequent watering in the summer, avoiding midday, with watering in the morning and evening. In other seasons, watering can be done every 5-6 days, generally depending on the dryness of the soil. If the soil is dry and white, it needs watering.
Fertilization method
Rosemary does not require much fertilizer, with 2-3 applications per year being sufficient. Fertilize along the edge of the pot with decomposed organic fertilizer, taking care to apply a thin layer of fertilizer frequently, with no need for too much of each application and the concentration should not be too high.
Pruning method
Pruning can be done every 3 months after planting rosemary. When pruning, do not exceed half the length of the branches. During the growing period, it is necessary to prune dense and overlapping branches to increase ventilation and light penetration, which will also enhance the overall ornamental value and prevent a cluttered appearance.
Precautions for rosemary cultivation
For those growing rosemary for the first time, it is important to note that although more watering is needed in the summer due to rapid evaporation of water, it is not advisable to water excessively. After flowering, a dilute fertilizer can be applied, but chemical fertilizers should be avoided. For home care, a small amount of fermented rice water can also be used.
