Rosemary is a common vanilla plant that is loved by people for its unique aroma and medicinal properties. It is not difficult to breed rosemary, and the following will introduce the cultivation methods and precautions of rosemary.
1. Soil. Rosemary prefers well-drained, loose, breathable, fertile soil. It is recommended to use humus, garden soil and vermiculite and other materials to mix according to the ratio of 1:1:1, and then add an appropriate amount of well-decomposed organic fertilizer as a substrate.
2. Illumination. Rosemary needs plenty of sunlight and should be kept in a sunny place during growth and receive at least 4 hours of direct sunlight per day. If there is not enough light, it will cause the growth and aroma to fade.
3. Temperature. The suitable growth temperature for rosemary is 15 -25 . In the summer heat, pay attention to shade and cool down to avoid damage to the plants. In winter, rosemary should be kept indoors in a warm and sunny place, and the temperature should be kept above 5 to avoid frost damage.
Fourth, moisture. Rosemary prefers moist environments but is afraid of waterlogging. When watering, the principle of "seeing dry and wet" should be followed, that is, waiting for the soil surface to dry slightly before watering, so as to avoid excessive watering and water accumulation. During the growing period, the plants can be sprayed with water frequently to keep the air humidity above 60%.
5. Fertilization. Rosemary requires adequate nutrients and should be fertilized regularly during growth. It is recommended to sprinkle an appropriate amount of compound fertilizer or well-rotted organic fertilizer on the surface of the potting soil, and then water it to dissolve it to promote the growth of the plant. In the vigorous growth period, nitrogen, phosphorus and potassium compound fertilizer can be applied every half month.
6. Pruning. Rosemary grows faster and needs to be pruned and shaped. When pruning, excessively long branches should be cut short to promote plant branching and increase density. At the same time, you can also cut off the yellowed leaves and residual flowers to keep the beauty and health of the plant.
7. Reproduction. Rosemary can be propagated by cuttings or seeding. The cuttings method is to cut the young branches on the robust mother plant, about 8-10 cm long, and insert them into the prepared substrate to keep the temperature and humidity appropriate, and generally take root and survive in about half a month. The sowing method involves sprinkling the seeds on the surface of the prepared potting soil, then covering them with a thin layer of soil, gently compacting them, and placing them in a warm and moist environment to wait for germination.
8. Pest control.
Rosemary has fewer pests and diseases, but it can also have some problems if it is not properly maintained. Common pests and diseases are anthracnose, aphids, etc. When pests and diseases occur, measures should be taken in time to prevent and control them, such as spraying plants and potting soil surfaces with corresponding drugs.
In conclusion, the cultivation of rosemary needs to pay attention to the problems of soil, light, temperature, moisture, fertilization, pruning and propagation. Only with the right cultivation methods and careful care can rosemary thrive and exude its unique aroma and medicinal properties.
