What are the cultivation methods and precautions of rosemary

Rosemary growth habits

Rosemary is a plant of the dicotyledonous class, Lamiaceae family, and Rosmarinus genus. Common methods of reproduction include seed propagation, cutting propagation, and layering propagation, with layering propagation being the most commonly used method.

The main varieties of rosemary are: upright white rosemary, creeping rosemary, Australian rosemary, coniferous rosemary, upright pink rosemary, variegated rosemary, rosemary, golden rosemary, upright narrow-leaf rosemary, upright broad-leaf Rex rosemary, blue boy rosemary, etc.

Rosemary cultivation method

Rosemary prefers a cool, dry and sunny environment. The choice of flower pots is very important. Unglazed clay pots have the best air permeability and drainage. The diameter of the flower pot can be about 20 cm. If it is too large, it will be difficult to control the amount of water. In addition, rosemary grows slowly, so the flower pot should not be too large.

Rosemary is a relatively cold-resistant plant that can tolerate an environment of minus 5 degrees Celsius. It can overwinter outdoors in the south, but in extremely cold areas, it is still necessary to take good warming measures. The temperature is high in summer, so ventilation and cooling are needed to promote its growth. It is suitable for planting in well-drained, organic-rich sandy soil, and can be placed in sufficient sunlight for maintenance all year round.

Watering method

Rosemary needs to be watered frequently in summer. Do not water it at noon, but once in the morning and evening. In other seasons, water it every 5-6 days. Generally, water it according to the dryness and wetness of the soil. If it is dry and white, it needs watering.

Fertilization method

Rosemary does not require much fertilizer. About two or three times a year is enough. Apply decomposed organic fertilizer along the edge of the flowerpot. Pay attention to applying thin fertilizers frequently. The amount used each time does not need to be too much, and the concentration should not be too high.

Pruning methods

Rosemary can be pruned every three months after planting. Each pruning should not exceed half of the branch length. During the growth period, dense and overlapping branches and leaves need to be pruned in time to increase the ventilation and light transmittance of the plant, which will also increase the overall ornamental value and prevent it from appearing messy.

Rosemary cultivation precautions

If you are growing rosemary for the first time, you should pay attention that water evaporates quickly in summer. Although you need to water it more often, you cannot water it too much. You can apply some dilute fertilizer to the plant after it blooms, but it is best not to use chemical fertilizer. If you are caring for it at home, you can also water it with some fermented rice water.
