Orchids, known as "gentlemen among flowers", have been loved by people since ancient times. In the northern part of China, although the climate is cold, beautiful potted orchids can still be cultivated. This article will introduce you to the breeding skills of potted orchids in the north, helping you to enjoy the beauty of these flowers in cold regions.
Choose the right orchid varietyThe choice of potted orchids in the north is crucial. Due to the cold climate in the north, it is necessary to choose varieties that are more cold-tolerant, such as black orchids and spring orchids. These varieties have strong adaptability and can grow in the cold climate conditions of the north.
Suitable breeding environment1. Light: Potted orchids in the north require plenty of light, but direct sunlight should be avoided. They can be grown on indoor balconies or rooms with sufficient sunlight.
2. Temperature: It is cold in the north in winter, so orchids should be placed in warm indoor areas, with a temperature maintained between 15-25℃.
3. Humidity: Orchids prefer a humid environment. Since the air in the north is dry in winter, a humidifier or spraying water can be used to increase indoor humidity.
Soil selection and watering1. Soil: The soil for potted orchids in the north should have good breathability and strong drainage, such as leaf mold and coarse sand, with a slightly acidic pH value.
2. Watering: The temperature in the north is low in winter, and the water requirement of orchids decreases. When watering, avoid waterlogging and keep the soil slightly moist.
Fertilizing and pruning1. Fertilizing: Potted orchids in the north can be fertilized with a small amount of compound fertilizer during the growing season (spring and autumn), once a month. In winter, fertilization should be reduced to prevent the plants from growing too tall.
2. Pruning: During the growth of orchids, withered and yellow leaves and weak branches should be pruned in time to keep the plants ventilated and well-lit.
Pest and disease controlPotted orchids in the north are prone to pest and disease attacks, such as leaf spot disease and aphids. The prevention and control methods are as follows:
1. Keep the plants ventilated and well-lit to reduce the occurrence of diseases and pests.
2. Regularly spray pesticides, such as carbendazim and pymetrozine.
3. When pests and diseases are found, clear away the weak and diseased leaves in time to prevent them from spreading.
Although breeding potted orchids in the north has certain difficulties, as long as you master the correct breeding techniques, you can grow beautiful flowers in cold regions. I hope this article is helpful to you and wish you success in breeding!
